-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, religion, or sexual identity
-and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-* Demonstrating empathy and kindness toward other people
-* Being respectful of differing opinions, viewpoints, and experiences
-* Giving and gracefully accepting constructive feedback
-* Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
-* Focusing on what is best not just for us as individuals, but for the
-  overall community
-
-Examples of unacceptable behavior include:
-
-* The use of sexualized language or imagery, and sexual attention or
-  advances of any kind
-* Trolling, insulting or derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or email
-  address, without their explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-support@sftpgo.com.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series
-of actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or
-permanent ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior,  harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within
-the community.

+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
 
   When we speak of free software, we are referring to freedom, not

 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 
-  Developers that use our General Public Licenses protect your rights
-with two steps: (1) assert copyright on the software, and (2) offer
-you this License which gives you legal permission to copy, distribute
-and/or modify the software.
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
 
-  A secondary benefit of defending all users' freedom is that
-improvements made in alternate versions of the program, if they
-receive widespread use, become available for other developers to
-incorporate.  Many developers of free software are heartened and
-encouraged by the resulting cooperation.  However, in the case of
-software used on network servers, this result may fail to come about.
-The GNU General Public License permits making a modified version and
-letting the public access it on a server without ever releasing its
-source code to the public.
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
 
-  The GNU Affero General Public License is designed specifically to
-ensure that, in such cases, the modified source code becomes available
-to the community.  It requires the operator of a network server to
-provide the source code of the modified version running there to the
-users of that server.  Therefore, public use of a modified version, on
-a publicly accessible server, gives the public access to the source
-code of the modified version.
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
 
-  An older license, called the Affero General Public License and
-published by Affero, was designed to accomplish similar goals.  This is
-a different license, not a version of the Affero GPL, but Affero has
-released a new version of the Affero GPL which permits relicensing under
-this license.
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.

-SFTPGo is an open-source project with a sustainable business model. We offer two editions to suit different requirements, ensuring the project remains healthy and maintained for everyone.
+## Platforms
 
-### Open Source (Community)
+SFTPGo is developed and tested on Linux. After each commit, the code is automatically built and tested on Linux, macOS and Windows using a [GitHub Action](./.github/workflows/development.yml). Other UNIX variants such as \*BSD should work too.
 
-Free, Copyleft (AGPLv3), Community Supported. The Community edition is a fully functional, production-ready solution widely adopted worldwide. It includes all the core protocols, storage backends, and the WebAdmin/WebClient UIs. It is ideal for:
+## Requirements
 
-- Standard file transfer needs.
-- Integrating storage backends (S3, GCS, Azure Blob) with legacy protocols.
-- Projects that are comfortable with AGPLv3 licensing.
+- Go 1.13 or higher as build only dependency.
+- A suitable SQL server or key/value store to use as data provider: PostgreSQL 9.4+ or MySQL 5.6+ or SQLite 3.x or bbolt 1.3.x
 
-### SFTPGo Enterprise
+## Installation
 
-Commercial License, Professional Support, ISO 27001 Vendor. The Enterprise edition is built on the same core but extends it for mission-critical environments, compliance-heavy industries, and advanced workflows. It is a drop-in replacement (seamless upgrade).

+### Data provider initialization
 
-## Documentation
+Before starting the SFTPGo server, please ensure that the configured data provider is properly initialized.
 
-You can explore all supported features and configuration options at [docs.sftpgo.com](https://docs.sftpgo.com/latest/).
+SQL based data providers (SQLite, MySQL, PostgreSQL) require the creation of a database containing the required tables. Memory and bolt data providers do not require an initialization.
 
-**Note:** The link above refers to the **Community Edition**.
-For details on **Enterprise Edition**, please refer to the [Enterprise Documentation](https://docs.sftpgo.com/enterprise/).
+After configuring the data provider using the configuration file, you can create the required database structure using the `initprovider` command.
+For SQLite provider, the `initprovider` command will auto create the database file, if missing, and the required tables.
+For PostgreSQL and MySQL providers, you need to create the configured database, and the `initprovider` command will create the required tables.
 
-## Support
+For example, you can simply execute the following command from the configuration directory:
 
-- **Community Support**: use [GitHub Discussions](https://github.com/drakkan/sftpgo/discussions) to ask questions, share feedback, and engage with other users.
-- **Commercial Support**: If you require guaranteed SLAs, expert guidance, or the advanced features listed above, check out [SFTPGo Enterprise](https://sftpgo.com).
+```bash
+sftpgo initprovider
+```
 
-SFTPGo Enterprise is available as:
+Take a look at the CLI usage to learn how to specify a different configuration file:
 
-- On-premises: Full control on your infrastructure. More details: [sftpgo.com/on-premises](https://sftpgo.com/on-premises)
-- Fully managed SaaS: We handle the infrastructure. More details: [sftpgo.com/saas](https://sftpgo.com/saas)
+```bash
+sftpgo initprovider --help
+```
 
-## Internationalization
+The `initprovider` command is enough for new installations. From now on, the database structure will be automatically checked and updated, if required, at startup.
 
-The translations are available via [Crowdin](https://crowdin.com/project/sftpgo), who have granted us an open source license.
+#### Upgrading
 
-Before translating please take a look at our contribution [guidelines](https://docs.sftpgo.com/latest/web-interfaces/#internationalization).
+If you are upgrading from version 0.9.5 or before, you have to manually execute the SQL scripts to create the required database structure. These scripts can be found inside the source tree [sql](./sql "sql") directory. The SQL scripts filename is, by convention, the date as `YYYYMMDD` and the suffix `.sql`. You need to apply all the SQL scripts for your database ordered by name. For example, `20190828.sql` must be applied before `20191112.sql`, and so on.
+Example for SQLite: `find sql/sqlite/ -type f -iname '*.sql' -print | sort -n | xargs cat | sqlite3 sftpgo.db`.
+After applying these scripts, your database structure is the same as the one obtained using `initprovider` for new installations, so from now on, you don't have to manually upgrade your database anymore.
 
-## Release Cadence
+## Authentication options
 
-SFTPGo follows a feature-driven release cycle.
+### External Authentication
 
-- Enterprise Edition: Receives major new features first and follows a faster [release cadence](https://docs.sftpgo.com/enterprise/changelog/).
-- Community Edition: Remains maintained, receiving bug fixes, security updates, and updates to core features.
+Custom authentication methods can easily be added. SFTPGo supports external authentication modules, and writing a new backend can be as simple as a few lines of shell script. More information can be found [here](./docs/external-auth.md).
+
+### Keyboard Interactive Authentication
+
+Keyboard interactive authentication is, in general, a series of questions asked by the server with responses provided by the client.
+This authentication method is typically used for multi-factor authentication.
+
+More information can be found [here](./docs/keyboard-interactive.md).
+
+## Dynamic user creation or modification
+
+A user can be created or modified by an external program just before the login. More information about this can be found [here](./docs/dynamic-user-mod.md).
+
+## Custom Actions
+
+SFTPGo allows to configure custom commands and/or HTTP notifications on file upload, download, delete, rename, on SSH commands and on user add, update and delete.
+
+More information about custom actions can be found [here](./docs/custom-actions.md).
+
+## Virtual folders
+
+Directories outside the user home directory can be exposed as virtual folders, more information [here](./docs/virtual-folders.md).
+
+## Storage backends
+
+### S3 Compabible Object Storage backends
+
+Each user can be mapped to whole bucket or to a bucket virtual folder. This way, the mapped bucket/virtual folder is exposed over SFTP/SCP. More information about S3 integration can be found [here](./docs/s3.md).
+
+### Google Cloud Storage backend
+
+Each user can be mapped with a Google Cloud Storage bucket or a bucket virtual folder. This way, the mapped bucket/virtual folder is exposed over SFTP/SCP. More information about Google Cloud Storage integration can be found [here](./docs/google-cloud-storage.md).
+
+### Other Storage backends
+
+Adding new storage backends is quite easy:
+
+- implement the [Fs interface](./vfs/vfs.go#L18 "interface for filesystem backends").
+- update the user method `GetFilesystem` to return the new backend
+- update the web interface and the REST API CLI
+- add the flags for the new storage backed to the `portable` mode
+
+Anyway, some backends require a pay per use account (or they offer free account for a limited time period only). To be able to add support for such backends or to review pull requests, please provide a test account. The test account must be available for enough time to be able to maintain the backend and do basic tests before each new release.
+
+## Brute force protection
+
+The [connection failed logs](./docs/logs.md) can be used for integration in tools such as [Fail2ban](http://www.fail2ban.org/). Example of [jails](./fail2ban/jails) and [filters](./fail2ban/filters) working with `systemd`/`journald` are available in fail2ban directory.
+
+## Account's configuration properties
+
+Details information about account configuration properties can be found [here](./docs/account.md).
+
+## Performance
+
+SFTPGo can easily saturate a Gigabit connection on low end hardware with no special configuration, this is generally enough for most use cases.
+
+More in-depth analysis of performance can be found [here](./docs/performance.md).

-# Security Policy
-
-## Supported Versions
-
-We actively maintain the latest stable release of SFTPGo. While we strive to keep the Open Source version secure and up-to-date, maintenance is performed on a best-effort basis by the community and contributors.
-
-## Scope and Dependency Policy
-
-Our security advisories focus on vulnerabilities found within the **SFTPGo codebase itself**.
-
-To ensure the long-term sustainability of the project, we handle upstream dependencies (like the Go standard library, external packages, or Docker base images) as follows:
-
-- Community Updates: For the Open Source version, vulnerabilities in upstream components (such as the Go standard library or third-party packages) are addressed during our **regular release cycles**. We generally do not provide immediate, out-of-band or ad-hoc releases to address dependency-only CVEs.
-- Empowering Users: One of the strengths of SFTPGo being open-source is that you have full control. If your security scanners require an immediate fix, you can always rebuild the project using the latest patched Go toolchain or updated dependencies.
-- Compatibility: We are committed to keeping SFTPGo compatible with the latest stable Go compiler. If an upstream fix breaks SFTPGo, fixing that becomes a priority for us.
-- Professional Needs: We understand that some organizations have strict compliance requirements or internal SLAs that require guaranteed, immediate response times and out-of-band patches. For these cases, we offer [SFTPGo Enterprise](https://sftpgo.com/on-premises) to cover the additional maintenance and support overhead.
-
-## Reporting a Vulnerability
-
-To report (possible) security issues in SFTPGo, please either send a mail to the [SFTPGo Team](mailto:support@sftpgo.com) or use Github's [private reporting feature](https://github.com/drakkan/sftpgo/security/advisories/new).

+# Dockerfile based on Debian stable
+
+Please read the comments inside the `Dockerfile` to learn how to customize things for your setup.
+
+You can build the container image using `docker build`, for example:
+
+```bash
+docker build -t="drakkan/sftpgo" .
+```
+
+This will build master of github.com/drakkan/sftpgo.
+
+To build the latest tag you can add `--build-arg TAG=LATEST` and to build a specific tag/commit you can use for example `TAG=0.9.6`, like this:
+
+```bash
+docker build -t="drakkan/sftpgo" --build-arg TAG=0.9.6 .
+```
+
+To specify the features to build you can add `--build-arg FEATURES=<build features comma separated>`. For example you can disable SQLite and S3 support like this:
+
+```bash
+docker build -t="drakkan/sftpgo" --build-arg FEATURES=nosqlite,nos3 .
+```
+
+Please take a look at the [build from source](./../../../docs/build-from-source.md) documentation for the complete list of the features that can be disabled.
+
+Now create the required folders on the host system, for example:
+
+```bash
+sudo mkdir -p /srv/sftpgo/data /srv/sftpgo/config /srv/sftpgo/backups
+```
+
+and give write access to them to the UID/GID defined inside the `Dockerfile`. You can choose to create a new user, on the host system, with a matching UID/GID pair, or simply do something like this:
+
+```bash
+sudo chown -R <UID>:<GID> /srv/sftpgo/data /srv/sftpgo/config /srv/sftpgo/backups
+```
+
+Download the default configuration file and edit it as you need:
+
+```bash
+sudo curl https://raw.githubusercontent.com/drakkan/sftpgo/master/sftpgo.json -o /srv/sftpgo/config/sftpgo.json
+```
+
+Initialize the configured provider. For PostgreSQL and MySQL providers you need to create the configured database and the `initprovider` command will create the required tables:
+
+```bash
+docker run --name sftpgo --mount type=bind,source=/srv/sftpgo/config,target=/app/config drakkan/sftpgo initprovider -c /app/config
+```
+
+and finally you can run the image using something like this:
+
+```bash
+docker rm sftpgo && docker run --name sftpgo -p 8080:8080 -p 2022:2022 --mount type=bind,source=/srv/sftpgo/data,target=/app/data --mount type=bind,source=/srv/sftpgo/config,target=/app/config --mount type=bind,source=/srv/sftpgo/backups,target=/app/backups drakkan/sftpgo

+# Account's configuration properties
+
+For each account, the following properties can be configured:
+
+- `username`
+- `password` used for password authentication. For users created using SFTPGo REST API, if the password has no known hashing algo prefix, it will be stored using argon2id. SFTPGo supports checking passwords stored with bcrypt, pbkdf2, md5crypt and sha512crypt too. For pbkdf2 the supported format is `$<algo>$<iterations>$<salt>$<hashed pwd base64 encoded>`, where algo is `pbkdf2-sha1` or `pbkdf2-sha256` or `pbkdf2-sha512` or `$pbkdf2-b64salt-sha256$`. For example the `pbkdf2-sha256` of the word `password` using 150000 iterations and `E86a9YMX3zC7` as salt must be stored as `$pbkdf2-sha256$150000$E86a9YMX3zC7$R5J62hsSq+pYw00hLLPKBbcGXmq7fj5+/M0IFoYtZbo=`. In pbkdf2 variant with `b64salt` the salt is base64 encoded. For bcrypt the format must be the one supported by golang's [crypto/bcrypt](https://godoc.org/golang.org/x/crypto/bcrypt) package, for example the password `secret` with cost `14` must be stored as `$2a$14$ajq8Q7fbtFRQvXpdCq7Jcuy.Rx1h/L4J60Otx.gyNLbAYctGMJ9tK`. For md5crypt and sha512crypt we support the format used in `/etc/shadow` with the `$1$` and `$6$` prefix, this is useful if you are migrating from Unix system user accounts. We support Apache md5crypt (`$apr1$` prefix) too. Using the REST API you can send a password hashed as bcrypt, pbkdf2, md5crypt or sha512crypt and it will be stored as is.
+- `public_keys` array of public keys. At least one public key or the password is mandatory.
+- `status` 1 means "active", 0 "inactive". An inactive account cannot login.
+- `expiration_date` expiration date as unix timestamp in milliseconds. An expired account cannot login. 0 means no expiration.
+- `home_dir` the user cannot upload or download files outside this directory. Must be an absolute path. A local home directory is required for Cloud Storage Backends too: in this case it will store temporary files.
+- `virtual_folders` list of mappings between virtual SFTP/SCP paths and local filesystem paths outside the user home directory. More information can be found [here](./virtual-folders.md)
+- `uid`, `gid`. If SFTPGo runs as root system user then the created files and directories will be assigned to this system uid/gid. Ignored on windows or if SFTPGo runs as non root user: in this case files and directories for all SFTP users will be owned by the system user that runs SFTPGo.
+- `max_sessions` maximum concurrent sessions. 0 means unlimited.
+- `quota_size` maximum size allowed as bytes. 0 means unlimited.
+- `quota_files` maximum number of files allowed. 0 means unlimited.
+- `permissions` for SFTP paths. The following per directory permissions are supported:
+  - `*` all permissions are granted
+  - `list` list items is allowed
+  - `download` download files is allowed
+  - `upload` upload files is allowed
+  - `overwrite` overwrite an existing file, while uploading, is allowed. `upload` permission is required to allow file overwrite
+  - `delete` delete files or directories is allowed
+  - `rename` rename a file or a directory is allowed if this permission is granted on source and target path. You can enable rename in a more controlled way granting `delete` permission on source directory and `upload`/`create_dirs`/`create_symlinks` permissions on target directory
+  - `create_dirs` create directories is allowed
+  - `create_symlinks` create symbolic links is allowed
+  - `chmod` changing file or directory permissions is allowed. On Windows, only the 0200 bit (owner writable) of mode is used; it controls whether the file's read-only attribute is set or cleared. The other bits are currently unused. Use mode 0400 for a read-only file and 0600 for a readable+writable file.
+  - `chown` changing file or directory owner and group is allowed. Changing owner and group is not supported on Windows.
+  - `chtimes` changing file or directory access and modification time is allowed
+- `upload_bandwidth` maximum upload bandwidth as KB/s, 0 means unlimited.
+- `download_bandwidth` maximum download bandwidth as KB/s, 0 means unlimited.
+- `allowed_ip`, List of IP/Mask allowed to login. Any IP address not contained in this list cannot login. IP/Mask must be in CIDR notation as defined in RFC 4632 and RFC 4291, for example "192.0.2.0/24" or "2001:db8::/32"
+- `denied_ip`, List of IP/Mask not allowed to login. If an IP address is both allowed and denied then login will be denied
+- `denied_login_methods`, List of login methods not allowed. To enable multi-step authentication you have to allow only multi-step login methods. The following login methods are supported:
+  - `publickey`
+  - `password`
+  - `keyboard-interactive`
+  - `publickey+password`
+  - `publickey+keyboard-interactive`
+- `file_extensions`, list of struct. These restrictions do not apply to files listing for performance reasons, so a denied file cannot be downloaded/overwritten/renamed but it will still be listed in the list of files. Please note that these restrictions can be easily bypassed. Each struct contains the following fields:
+  - `allowed_extensions`, list of, case insensitive, allowed files extension. Shell like expansion is not supported so you have to specify `.jpg` and not `*.jpg`. Any file that does not end with this suffix will be denied
+  - `denied_extensions`, list of, case insensitive, denied files extension. Denied file extensions are evaluated before the allowed ones
+  - `path`, SFTP/SCP path, if no other specific filter is defined, the filter apply for sub directories too. For example if filters are defined for the paths `/` and `/sub` then the filters for `/` are applied for any file outside the `/sub` directory
+- `fs_provider`, filesystem to serve via SFTP. Local filesystem and S3 Compatible Object Storage are supported
+- `s3_bucket`, required for S3 filesystem
+- `s3_region`, required for S3 filesystem. Must match the region for your bucket. You can find here the list of available [AWS regions](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html#concepts-available-regions). For example if your bucket is at `Frankfurt` you have to set the region to `eu-central-1`
+- `s3_access_key`
+- `s3_access_secret`, if provided it is stored encrypted (AES-256-GCM). You can leave access key and access secret blank to use credentials from environment
+- `s3_endpoint`, specifies a S3 endpoint (server) different from AWS. It is not required if you are connecting to AWS
+- `s3_storage_class`, leave blank to use the default or specify a valid AWS [storage class](https://docs.aws.amazon.com/AmazonS3/latest/dev/storage-class-intro.html)
+- `s3_key_prefix`, allows to restrict access to the folder identified by this prefix and its contents
+- `s3_upload_part_size`, the buffer size for multipart uploads (MB). Zero means the default (5 MB). Minimum is 5
+- `s3_upload_concurrency` how many parts are uploaded in parallel
+- `gcs_bucket`, required for GCS filesystem
+- `gcs_credentials`, Google Cloud Storage JSON credentials base64 encoded
+- `gcs_automatic_credentials`, integer. Set to 1 to use Application Default Credentials strategy or set to 0 to use explicit credentials via `gcs_credentials`
+- `gcs_storage_class`
+- `gcs_key_prefix`, allows to restrict access to the folder identified by this prefix and its contents
+
+These properties are stored inside the data provider.
+
+If you want to use your existing accounts, you have these options:
+
+- If your accounts are aleady stored inside a supported database, you can create a database view. Since a view is read only, you have to disable user management and quota tracking so SFTPGo will never try to write to the view
+- you can import your users inside SFTPGo. Take a look at [sftpgo_api_cli.py](../examples/rest-api-cli#convert-users-from-other-stores "SFTPGo API CLI example"), it can convert and import users from Linux system users and Pure-FTPd/ProFTPD virtual users
+- you can use an external authentication program

+# Build SFTPGo from source
+
+You can install the package to your [\$GOPATH](https://github.com/golang/go/wiki/GOPATH "GOPATH") with the [go tool](https://golang.org/cmd/go/ "go command") from shell:
+
+```bash
+go get -u github.com/drakkan/sftpgo
+```
+
+Or you can download the sources and use `go build`.
+
+Make sure [Git](https://git-scm.com/downloads) is installed on your machine and in your system's `PATH`.
+
+The following build tags are available:
+
+- `nogcs`, disable Google Cloud Storage backend, default enabled
+- `nos3`, disable S3 Compabible Object Storage backends, default enabled
+- `nobolt`, disable Bolt data provider, default enabled
+- `nomysql`, disable MySQL data provider, default enabled
+- `nopgsql`, disable PostgreSQL data provider, default enabled
+- `nosqlite`, disable SQLite data provider, default enabled
+- `noportable`, disable portable mode, default enabled
+- `nometrics`, disable Prometheus metrics, default enabled
+
+If no build tag is specified the build will include the default features.
+
+The optional [SQLite driver](https://github.com/mattn/go-sqlite3 "go-sqlite3") is a `CGO` package and so it requires a `C` compiler at build time.
+On Linux and macOS, a compiler is easy to install or already installed. On Windows, you need to download [MinGW-w64](https://sourceforge.net/projects/mingw-w64/files/) and build SFTPGo from its command prompt.
+
+The compiler is a build time only dependency. It is not required at runtime.
+
+Version info, such as git commit and build date, can be embedded setting the following string variables at build time:
+
+- `github.com/drakkan/sftpgo/version.commit`
+- `github.com/drakkan/sftpgo/version.date`
+
+For example, you can build using the following command:
+
+```bash
+go build -i -tags nogcs,nos3,nosqlite -ldflags "-s -w -X github.com/drakkan/sftpgo/version.commit=`git describe --always --dirty` -X github.com/drakkan/sftpgo/version.date=`date -u +%FT%TZ`" -o sftpgo
+```
+
+You should get a version that includes git commit, build date and available features like this one:
+
+```bash
+$ ./sftpgo -v
+SFTPGo 0.9.6-dev-b30614e-dirty-2020-06-19T11:04:56Z +metrics -gcs -s3 +bolt +mysql +pgsql -sqlite +portable

+# Custom Actions
+
+The `actions` struct inside the "sftpd" configuration section allows to configure the actions for file operations and SSH commands.
+The `hook` can be defined as the absolute path of your program or an HTTP URL.
+
+The `upload` condition includes both uploads to new files and overwrite of existing files. If an upload is aborted for quota limits SFTPGo tries to remove the partial file, so if the notification reports a zero size file and a quota exceeded error the file has been deleted. The `ssh_cmd` condition will be triggered after a command is successfully executed via SSH. `scp` will trigger the `download` and `upload` conditions and not `ssh_cmd`.
+The notification will indicate if an error is detected and so, for example, a partial file is uploaded.
+The `pre-delete` action, if defined, will be called just before files deletion. If the external command completes with a zero exit status or the HTTP notification response code is `200` then SFTPGo will assume that the file was already deleted/moved and so it will not try to remove the file and it will not execute the hook defined for the `delete` action.
+
+If the `hook` defines a path to an external program, then this program is invoked with the following arguments:
+
+- `action`, string, possible values are: `download`, `upload`, `pre-delete`,`delete`, `rename`, `ssh_cmd`
+- `username`
+- `path` is the full filesystem path, can be empty for some ssh commands
+- `target_path`, non-empty for `rename` action and for `sftpgo-copy` SSH command
+- `ssh_cmd`, non-empty for `ssh_cmd` action
+
+The external program can also read the following environment variables:
+
+- `SFTPGO_ACTION`
+- `SFTPGO_ACTION_USERNAME`
+- `SFTPGO_ACTION_PATH`
+- `SFTPGO_ACTION_TARGET`, non-empty for `rename` `SFTPGO_ACTION`
+- `SFTPGO_ACTION_SSH_CMD`, non-empty for `ssh_cmd` `SFTPGO_ACTION`
+- `SFTPGO_ACTION_FILE_SIZE`, non-empty for `upload`, `download` and `delete` `SFTPGO_ACTION`
+- `SFTPGO_ACTION_FS_PROVIDER`, `0` for local filesystem, `1` for S3 backend, `2` for Google Cloud Storage (GCS) backend
+- `SFTPGO_ACTION_BUCKET`, non-empty for S3 and GCS backends
+- `SFTPGO_ACTION_ENDPOINT`, non-empty for S3 backend if configured
+- `SFTPGO_ACTION_STATUS`, integer. 0 means a generic error occurred. 1 means no error, 2 means quota exceeded error
+
+Previous global environment variables aren't cleared when the script is called.
+The program must finish within 30 seconds.
+
+If the `hook` defines an HTTP URL then this URL will be invoked as HTTP POST. The request body will contain a JSON serialized struct with the following fields:
+
+- `action`
+- `username`
+- `path`
+- `target_path`, not null for `rename` action
+- `ssh_cmd`, not null for `ssh_cmd` action
+- `file_size`, not null for `upload`, `download`, `delete` actions
+- `fs_provider`, `0` for local filesystem, `1` for S3 backend, `2` for Google Cloud Storage (GCS) backend
+- `bucket`, not null for S3 and GCS backends
+- `endpoint`, not null for S3 backend if configured
+- `status`, integer. 0 means a generic error occurred. 1 means no error, 2 means quota exceeded error
+
+The HTTP request will use the global configuration for HTTP clients.
+
+The `actions` struct inside the "data_provider" configuration section allows you to configure actions on user add, update, delete.
+
+Actions will not be fired for internal updates, such as the last login or the user quota fields, or after external authentication.
+

+# Dynamic user creation or modification
+
+Dynamic user creation or modification is supported via an external program or an HTTP URL that can be invoked just before the user login.
+To enable dynamic user modification, you must set the absolute path of your program or an HTTP URL using the `pre_login_hook` key in your configuration file.
+
+The external program can read the following environment variables to get info about the user trying to login:
+
+- `SFTPGO_LOGIND_USER`, it contains the user trying to login serialized as JSON. A JSON serialized user id equal to zero means the user does not exists inside SFTPGo
+- `SFTPGO_LOGIND_METHOD`, possible values are: `password`, `publickey` and `keyboard-interactive`
+
+The program must write, on its the standard output:
+
+- an empty string (or no response at all) if the user should not be created/updated
+- or the SFTPGo user, JSON serialized, if you want create or update the given user
+
+If the hook is an HTTP URL then it will be invoked as HTTP POST. The login method is added to the query string, for example `<http_url>?login_method=password`.
+The request body will contain the user trying to login serialized as JSON. If no modification is needed the HTTP response code must be 204, otherwise the response code must be 200 and the response body a valid SFTPGo user serialized as JSON.
+
+Actions defined for user's updates will not be executed in this case.
+
+The JSON response can include only the fields to update instead of the full user. For example, if you want to disable the user, you can return a response like this:
+
+```json
+{"status": 0}
+```
+
+Please note that if you want to create a new user, the pre-login hook response must include all the mandatory user fields.
+
+The program hook must finish within 30 seconds, the HTTP hook will use the global configuration for HTTP clients.
+
+If an error happens while executing the hook then login will be denied.
+
+"Dynamic user creation or modification" and "External Authentication" are mutally exclusive, they are quite similar, the difference is that "External Authentication" returns an already authenticated user while using "Dynamic users modification" you simply create or update a user. The authentication will be checked inside SFTPGo.
+In other words while using "External Authentication" the external program receives the credentials of the user trying to login (for example the clear text password) and it need to validate them. While using "Dynamic users modification" the pre-login program receives the user stored inside the dataprovider (it includes the hashed password if any) and it can modify it, after the modification SFTPGo will check the credentials of the user trying to login.
+
+Let's see a very basic example. Our sample program will grant access to the existing user `test_user` only in the time range 10:00-18:00. Other users will not be modified since the program will terminate with no output.
+
+```shell
+#!/bin/bash
+
+CURRENT_TIME=`date +%H:%M`
+if [[ "$SFTPGO_LOGIND_USER" =~ "\"test_user\"" ]]
+then
+  if [[ $CURRENT_TIME > "18:00" || $CURRENT_TIME < "10:00" ]]
+  then
+    echo '{"status":0}'
+  else
+    echo '{"status":1}'
+  fi
+fi
+```
+
+Please note that this is a demo program and it might not work in all cases. For example, the username should be obtained by parsing the JSON serialized user and not by searching the username inside the JSON as shown here.

+# External Authentication
+
+To enable external authentication, you must set the absolute path of your authentication program or an HTTP URL using the `external_auth_hook` key in your configuration file.
+
+The external program can read the following environment variables to get info about the user trying to authenticate:
+
+- `SFTPGO_AUTHD_USERNAME`
+- `SFTPGO_AUTHD_PASSWORD`, not empty for password authentication
+- `SFTPGO_AUTHD_PUBLIC_KEY`, not empty for public key authentication
+- `SFTPGO_AUTHD_KEYBOARD_INTERACTIVE`, not empty for keyboard interactive authentication
+
+Previous global environment variables aren't cleared when the script is called. The content of these variables is _not_ quoted. They may contain special characters. They are under the control of a possibly malicious remote user.
+The program must write, on its standard output, a valid SFTPGo user serialized as JSON if the authentication succeed or a user with an empty username if the authentication fails.
+
+If the hook is an HTTP URL then it will be invoked as HTTP POST. The request body will contain a JSON serialized struct with the following fields:
+
+- `username`
+- `password`, not empty for password authentication
+- `public_key`, not empty for public key authentication
+- `keyboard_interactive`, not empty for keyboard interactive authentication
+
+If authentication succeed the HTTP response code must be 200 and the response body a valid SFTPGo user serialized as JSON. If the authentication fails the HTTP response code must be != 200 or the response body must be empty.
+
+If the authentication succeeds, the user will be automatically added/updated inside the defined data provider. Actions defined for users added/updated will not be executed in this case.
+The external hook should check authentication only. If there are login restrictions such as user disabled, expired, or login allowed only from specific IP addresses, it is enough to populate the matching user fields, and these conditions will be checked in the same way as for built-in users.
+The program hook must finish within 30 seconds, the HTTP hook timeout will use the global configuration for HTTP clients.
+
+This method is slower than built-in authentication, but it's very flexible as anyone can easily write his own authentication hooks.
+You can also restrict the authentication scope for the hook using the `external_auth_scope` configuration key:
+
+- 0 means all supported authetication scopes. The external hook will be used for password, public key and keyboard interactive authentication
+- 1 means passwords only
+- 2 means public keys only
+- 4 means keyboard interactive only
+
+You can combine the scopes. For example, 3 means password and public key, 5 means password and keyboard interactive, and so on.
+
+Let's see a very basic example. Our sample authentication program will only accept user `test_user` with any password or public key.
+
+```shell
+#!/bin/sh
+
+if test "$SFTPGO_AUTHD_USERNAME" = "test_user"; then
+  echo '{"status":1,"username":"test_user","expiration_date":0,"home_dir":"/tmp/test_user","uid":0,"gid":0,"max_sessions":0,"quota_size":0,"quota_files":100000,"permissions":{"/":["*"],"/somedir":["list","download"]},"upload_bandwidth":0,"download_bandwidth":0,"filters":{"allowed_ip":[],"denied_ip":[]},"public_keys":[]}'
+else
+  echo '{"username":""}'
+fi
+```

+# Configuring SFTPGo
+
+## Command line options
+
+The SFTPGo executable can be used this way:
+
+```console
+Usage:
+  sftpgo [command]
+
+Available Commands:
+  help         Help about any command
+  initprovider Initializes the configured data provider
+  portable     Serve a single directory
+  serve        Start the SFTP Server
+
+Flags:
+  -h, --help      help for sftpgo
+  -v, --version
+
+ Use "sftpgo [command] --help" for more information about a command
+```
+
+The `serve` command supports the following flags:
+
+- `--config-dir` string. Location of the config dir. This directory should contain the configuration file and is used as the base directory for any files that use a relative path (eg. the private keys for the SFTP server, the SQLite or bblot database if you use SQLite or bbolt as data provider). The default value is "." or the value of `SFTPGO_CONFIG_DIR` environment variable.
+- `--config-file` string. Name of the configuration file. It must be the name of a file stored in `config-dir`, not the absolute path to the configuration file. The specified file name must have no extension because we automatically append JSON, YAML, TOML, HCL and Java extensions when we search for the file. The default value is "sftpgo" (and therefore `sftpgo.json`, `sftpgo.yaml` and so on are searched) or the value of `SFTPGO_CONFIG_FILE` environment variable.
+- `--log-compress` boolean. Determine if the rotated log files should be compressed using gzip. Default `false` or the value of `SFTPGO_LOG_COMPRESS` environment variable (1 or `true`, 0 or `false`). It is unused if `log-file-path` is empty.
+- `--log-file-path` string. Location for the log file, default "sftpgo.log" or the value of `SFTPGO_LOG_FILE_PATH` environment variable. Leave empty to write logs to the standard error.
+- `--log-max-age` int. Maximum number of days to retain old log files. Default 28 or the value of `SFTPGO_LOG_MAX_AGE` environment variable. It is unused if `log-file-path` is empty.
+- `--log-max-backups` int. Maximum number of old log files to retain. Default 5 or the value of `SFTPGO_LOG_MAX_BACKUPS` environment variable. It is unused if `log-file-path` is empty.
+- `--log-max-size` int. Maximum size in megabytes of the log file before it gets rotated. Default 10 or the value of `SFTPGO_LOG_MAX_SIZE` environment variable. It is unused if `log-file-path` is empty.
+- `--log-verbose` boolean. Enable verbose logs. Default `true` or the value of `SFTPGO_LOG_VERBOSE` environment variable (1 or `true`, 0 or `false`).
+
+Log file can be rotated on demand sending a `SIGUSR1` signal on Unix based systems and using the command `sftpgo service rotatelogs` on Windows.
+
+If you don't configure any private host key, the daemon will use `id_rsa` and `id_ecdsa` in the configuration directory. If these files don't exist, the daemon will attempt to autogenerate them (if the user that executes SFTPGo has write access to the `config-dir`). The server supports any private key format supported by [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/keys.go#L33).
+
+## Configuration file
+
+The configuration file contains the following sections:
+
+- **"sftpd"**, the configuration for the SFTP server
+  - `bind_port`, integer. The port used for serving SFTP requests. Default: 2022
+  - `bind_address`, string. Leave blank to listen on all available network interfaces. Default: ""
+  - `idle_timeout`, integer. Time in minutes after which an idle client will be disconnected. 0 means disabled. Default: 15
+  - `max_auth_tries` integer. Maximum number of authentication attempts permitted per connection. If set to a negative number, the number of attempts is unlimited. If set to zero, the number of attempts are limited to 6.
+  - `umask`, string. Umask for the new files and directories. This setting has no effect on Windows. Default: "0022"
+  - `banner`, string. Identification string used by the server. Leave empty to use the default banner. Default `SFTPGo_<version>`, for example `SSH-2.0-SFTPGo_0.9.5`
+  - `upload_mode` integer. 0 means standard: the files are uploaded directly to the requested path. 1 means atomic: files are uploaded to a temporary path and renamed to the requested path when the client ends the upload. Atomic mode avoids problems such as a web server that serves partial files when the files are being uploaded. In atomic mode, if there is an upload error, the temporary file is deleted and so the requested upload path will not contain a partial file. 2 means atomic with resume support: same as atomic but if there is an upload error, the temporary file is renamed to the requested path and not deleted. This way, a client can reconnect and resume the upload.
+  - `actions`, struct. It contains the command to execute and/or the HTTP URL to notify and the trigger conditions. See the "Custom Actions" paragraph for more details
+    - `execute_on`, list of strings. Valid values are `download`, `upload`, `pre-delete`, `delete`, `rename`, `ssh_cmd`. Leave empty to disable actions.
+    - `command`, string. Deprecated please use `hook`.
+    - `http_notification_url`, a valid URL. Deprecated please use `hook`.
+    - `hook`, string. Absolute path to the command to execute or HTTP URL to notify.
+  - `keys`, struct array. Deprecated, please use `host_keys`.
+    - `private_key`, path to the private key file. It can be a path relative to the config dir or an absolute one.
+  - `host_keys`, list of strings. It contains the daemon's private host keys. Each host key can be defined as a path relative to the configuration directory or an absolute one. If empty, the daemon will search or try to generate `id_rsa` and `id_ecdsa` keys inside the configuration directory. If you configure absolute paths to files named `id_rsa` and/or `id_ecdsa` then SFTPGo will try to generate these keys using the default settings.
+  - `kex_algorithms`, list of strings. Available KEX (Key Exchange) algorithms in preference order. Leave empty to use default values. The supported values can be found here: [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/common.go#L46 "Supported kex algos")
+  - `ciphers`, list of strings. Allowed ciphers. Leave empty to use default values. The supported values can be found here: [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/common.go#L28 "Supported ciphers")
+  - `macs`, list of strings. Available MAC (message authentication code) algorithms in preference order. Leave empty to use default values. The supported values can be found here: [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/common.go#L84 "Supported MACs")
+  - `trusted_user_ca_keys`, list of public keys paths of certificate authorities that are trusted to sign user certificates for authentication. The paths can be absolute or relative to the configuration directory.
+  - `login_banner_file`, path to the login banner file. The contents of the specified file, if any, are sent to the remote user before authentication is allowed. It can be a path relative to the config dir or an absolute one. Leave empty to disable login banner.
+  - `setstat_mode`, integer. 0 means "normal mode": requests for changing permissions, owner/group and access/modification times are executed. 1 means "ignore mode": requests for changing permissions, owner/group and access/modification times are silently ignored.
+  - `enabled_ssh_commands`, list of enabled SSH commands. `*` enables all supported commands. More information can be found [here](./ssh-commands.md).
+  - `keyboard_interactive_auth_program`, string. Deprecated, please use `keyboard_interactive_auth_hook`.
+  - `keyboard_interactive_auth_hook`, string. Absolute path to an external program or an HTTP URL to invoke for keyboard interactive authentication. See the "Keyboard Interactive Authentication" paragraph for more details.
+  - `proxy_protocol`, integer. Support for [HAProxy PROXY protocol](https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt). If you are running SFTPGo behind a proxy server such as HAProxy, AWS ELB or NGNIX, you can enable the proxy protocol. It provides a convenient way to safely transport connection information such as a client's address across multiple layers of NAT or TCP proxies to get the real client IP address instead of the proxy IP. Both protocol versions 1 and 2 are supported. If the proxy protocol is enabled in SFTPGo then you have to enable the protocol in your proxy configuration too. For example, for HAProxy, add `send-proxy` or `send-proxy-v2` to each server configuration line. The following modes are supported:
+    - 0, disabled
+    - 1, enabled. Proxy header will be used and requests without proxy header will be accepted
+    - 2, required. Proxy header will be used and requests without proxy header will be rejected
+  - `proxy_allowed`, List of IP addresses and IP ranges allowed to send the proxy header:
+    - If `proxy_protocol` is set to 1 and we receive a proxy header from an IP that is not in the list then the connection will be accepted and the header will be ignored
+    - If `proxy_protocol` is set to 2 and we receive a proxy header from an IP that is not in the list then the connection will be rejected
+- **"data_provider"**, the configuration for the data provider
+  - `driver`, string. Supported drivers are `sqlite`, `mysql`, `postgresql`, `bolt`, `memory`
+  - `name`, string. Database name. For driver `sqlite` this can be the database name relative to the config dir or the absolute path to the SQLite database. For driver `memory` this is the (optional) path relative to the config dir or the absolute path to the users dump, obtained using the `dumpdata` REST API, to load. This dump will be loaded at startup and can be reloaded on demand sending a `SIGHUP` signal on Unix based systems and a `paramchange` request to the running service on Windows. The `memory` provider will not modify the provided file so quota usage and last login will not be persisted
+  - `host`, string. Database host. Leave empty for drivers `sqlite`, `bolt` and `memory`
+  - `port`, integer. Database port. Leave empty for drivers `sqlite`, `bolt` and `memory`
+  - `username`, string. Database user. Leave empty for drivers `sqlite`, `bolt` and `memory`
+  - `password`, string. Database password. Leave empty for drivers `sqlite`, `bolt` and `memory`
+  - `sslmode`, integer. Used for drivers `mysql` and `postgresql`. 0 disable SSL/TLS connections, 1 require ssl, 2 set ssl mode to `verify-ca` for driver `postgresql` and `skip-verify` for driver `mysql`, 3 set ssl mode to `verify-full` for driver `postgresql` and `preferred` for driver `mysql`
+  - `connectionstring`, string. Provide a custom database connection string. If not empty, this connection string will be used instead of building one using the previous parameters. Leave empty for drivers `bolt` and `memory`
+  - `sql_tables_prefix`, string. Prefix for SQL tables
+  - `manage_users`, integer. Set to 0 to disable users management, 1 to enable
+  - `track_quota`, integer. Set the preferred mode to track users quota between the following choices:
+    - 0, disable quota tracking. REST API to scan users home directories/virtual folders and update quota will do nothing
+    - 1, quota is updated each time a user uploads or deletes a file, even if the user has no quota restrictions
+    - 2, quota is updated each time a user uploads or deletes a file, but only for users with quota restrictions and for virtual folders. With this configuration, the `quota scan` and `folder_quota_scan` REST API can still be used to periodically update space usage for users without quota restrictions and for folders
+  - `pool_size`, integer. Sets the maximum number of open connections for `mysql` and `postgresql` driver. Default 0 (unlimited)
+  - `users_base_dir`, string. Users default base directory. If no home dir is defined while adding a new user, and this value is a valid absolute path, then the user home dir will be automatically defined as the path obtained joining the base dir and the username
+  - `actions`, struct. It contains the command to execute and/or the HTTP URL to notify and the trigger conditions. See the "Custom Actions" paragraph for more details
+    - `execute_on`, list of strings. Valid values are `add`, `update`, `delete`. `update` action will not be fired for internal updates such as the last login or the user quota fields.
+    - `command`, string. Deprecated please use `hook`.
+    - `http_notification_url`, a valid URL. Deprecated please use `hook`.
+    - `hook`, string. Absolute path to the command to execute or HTTP URL to notify.
+  - `external_auth_program`, string. Deprecated, please use `external_auth_hook`.
+  - `external_auth_hook`, string. Absolute path to an external program or an HTTP URL to invoke for users authentication. See the "External Authentication" paragraph for more details. Leave empty to disable.
+  - `external_auth_scope`, integer. 0 means all supported authetication scopes (passwords, public keys and keyboard interactive). 1 means passwords only. 2 means public keys only. 4 means key keyboard interactive only. The flags can be combined, for example 6 means public keys and keyboard interactive
+  - `credentials_path`, string. It defines the directory for storing user provided credential files such as Google Cloud Storage credentials. This can be an absolute path or a path relative to the config dir
+  - `pre_login_program`, string. Deprecated, please use `pre_login_hook`.
+  - `pre_login_hook`, string. Absolute path to an external program or an HTTP URL to invoke to modify user details just before the login. See the "Dynamic user modification" paragraph for more details. Leave empty to disable.
+- **"httpd"**, the configuration for the HTTP server used to serve REST API and to expose the built-in web interface
+  - `bind_port`, integer. The port used for serving HTTP requests. Set to 0 to disable HTTP server. Default: 8080
+  - `bind_address`, string. Leave blank to listen on all available network interfaces. Default: "127.0.0.1"
+  - `templates_path`, string. Path to the HTML web templates. This can be an absolute path or a path relative to the config dir
+  - `static_files_path`, string. Path to the static files for the web interface. This can be an absolute path or a path relative to the config dir. If both `templates_path` and `static_files_path` are empty the built-in web interface will be disabled
+  - `backups_path`, string. Path to the backup directory. This can be an absolute path or a path relative to the config dir. We don't allow backups in arbitrary paths for security reasons
+  - `auth_user_file`, string. Path to a file used to store usernames and passwords for basic authentication. This can be an absolute path or a path relative to the config dir. We support HTTP basic authentication, and the file format must conform to the one generated using the Apache `htpasswd` tool. The supported password formats are bcrypt (`$2y$` prefix) and md5 crypt (`$apr1$` prefix). If empty, HTTP authentication is disabled.
+  - `certificate_file`, string. Certificate for HTTPS. This can be an absolute path or a path relative to the config dir.
+  - `certificate_key_file`, string. Private key matching the above certificate. This can be an absolute path or a path relative to the config dir. If both the certificate and the private key are provided, the server will expect HTTPS connections. Certificate and key files can be reloaded on demand sending a `SIGHUP` signal on Unix based systems and a `paramchange` request to the running service on Windows.
+- **"http"**, the configuration for HTTP clients. HTTP clients are used for executing hooks such as the ones used for custom actions, external authentication and pre-login user modifications
+  - `timeout`, integer. Timeout specifies a time limit, in seconds, for requests.
+  - `ca_certificates`, list of strings. List of paths to extra CA certificates to trust. The paths can be absolute or relative to the config dir. Adding trusted CA certificates is a convenient way to use self-signed certificates without defeating the purpose of using TLS.
+  - `skip_tls_verify`, boolean. if enabled the HTTP client accepts any TLS certificate presented by the server and any host name in that certificate. In this mode, TLS is susceptible to man-in-the-middle attacks. This should be used only for testing.
+
+A full example showing the default config (in JSON format) can be found [here](../sftpgo.json).
+
+If you want to use a private host key that use an algorithm/setting different from the auto generated RSA/ECDSA keys, or more than two private keys, you can generate your own keys and replace the empty `keys` array with something like this:
+
+```json
+"host_keys": [
+  "id_rsa",
+  "id_ecdsa",
+  "id_ed25519"
+]
+```
+
+where `id_rsa`, `id_ecdsa` and `id_ed25519`, in this example, are files containing your generated keys. You can use absolute paths or paths relative to the configuration directory.
+
+If you want the default host keys generation in a directory different from the config dir, please specify absolute paths to files named `id_rsa` or `id_ecdsa` like this:
+
+```json
+"host_keys": [
+  "/etc/sftpgo/keys/id_rsa",
+  "/etc/sftpgo/keys/id_ecdsa"
+]
+```
+
+then SFTPGo will try to create `id_rsa` and `id_ecdsa`, if they are missing, inside the existing directory `/etc/sftpgo/keys`.
+
+The configuration can be read from JSON, TOML, YAML, HCL, envfile and Java properties config files. If your `config-file` flag is set to `sftpgo` (default value), you need to create a configuration file called `sftpgo.json` or `sftpgo.yaml` and so on inside `config-dir`.
+
+## Environment variables
+
+You can also override all the available configuration options using environment variables. SFTPGo will check for environment variables with a name matching the key uppercased and prefixed with the `SFTPGO_`. You need to use `__` to traverse a struct.
+
+Let's see some examples:
+
+- To set sftpd `bind_port`, you need to define the env var `SFTPGO_SFTPD__BIND_PORT`
+- To set the `execute_on` actions, you need to define the env var `SFTPGO_SFTPD__ACTIONS__EXECUTE_ON`. For example `SFTPGO_SFTPD__ACTIONS__EXECUTE_ON=upload,download`
+
+Please note that, to override configuration options with environment variables, a configuration file containing the options to override is required. You can, for example, deploy the default configuration file and then override the options you need to customize using environment variables.

+# Google Cloud Storage backend
+
+To connect SFTPGo to Google Cloud Storage you can use use the Application Default Credentials (ADC) strategy to try to find your application's credentials automatically or you can explicitly provide a JSON credentials file that you can obtain from the Google Cloud Console. Take a look [here](https://cloud.google.com/docs/authentication/production#providing_credentials_to_your_application) for details.
+
+Specifying a different `key_prefix`, you can assign different "folders" of the same bucket to different users. This is similar to a chroot directory for local filesystem. Each SFTP/SCP user can only access the assigned folder and its contents. The folder identified by `key_prefix` does not need to be pre-created.
+
+You can optionally specify a [storage class](https://cloud.google.com/storage/docs/storage-classes) too. Leave it blank to use the default storage class.
+
+The configured bucket must exist.
+
+Google Cloud Storage is exposed over HTTPS so if you are running SFTPGo as docker image please be sure to uncomment the line that install `ca-certificates`, inside your `Dockerfile`, to be able to properly verify certificate authorities.

+# Keyboard Interactive Authentication
+
+Keyboard interactive authentication is, in general, a series of questions asked by the server with responses provided by the client.
+This authentication method is typically used for multi-factor authentication.
+There are no restrictions on the number of questions asked on a particular authentication stage; there are also no restrictions on the number of stages involving different sets of questions.
+
+To enable keyboard interactive authentication, you must set the absolute path of your authentication program or an HTTP URL using the  `keyboard_interactive_auth_hook` key in your configuration file.
+
+The external program can read the following environment variables to get info about the user trying to authenticate:
+
+- `SFTPGO_AUTHD_USERNAME`
+- `SFTPGO_AUTHD_PASSWORD`, this is the hashed password as stored inside the data provider
+
+Previous global environment variables aren't cleared when the script is called. The content of these variables is _not_ quoted. They may contain special characters.
+
+The program must write the questions on its standard output, in a single line, using the following struct JSON serialized:
+
+- `instruction`, string. A short description to show to the user that is trying to authenticate. Can be empty or omitted
+- `questions`, list of questions to be asked to the user
+- `echos` list of boolean flags corresponding to the questions (so the lengths of both lists must be the same) and indicating whether user's reply for a particular question should be echoed on the screen while they are typing: true if it should be echoed, or false if it should be hidden.
+- `check_password` optional integer. Ask exactly one question and set this field to 1 if the expected answer is the user password and you want that SFTPGo checks it for you. If the password is correct, the returned response to the program is `OK`. If the password is wrong, the program will be terminated and an authentication error will be returned to the user that is trying to authenticate.
+- `auth_result`, integer. Set this field to 1 to indicate successful authentication. 0 is ignored. Any other value means authentication error. If this field is found and it is different from 0 then SFTPGo will not read any other questions from the external program, and it will finalize the authentication.
+
+SFTPGo writes the user answers to the program standard input, one per line, in the same order as the questions.
+Please be sure that your program receives the answers for all the issued questions before asking for the next ones.
+
+Keyboard interactive authentication can be chained to the external authentication.
+The authentication must finish within 60 seconds.
+
+Let's see a very basic example. Our sample keyboard interactive authentication program will ask for 2 sets of questions and accept the user if the answer to the last question is `answer3`.
+
+```shell
+#!/bin/sh
+
+echo '{"questions":["Question1: ","Question2: "],"instruction":"This is a sample for keyboard interactive authentication","echos":[true,false]}'
+
+read ANSWER1
+read ANSWER2
+
+echo '{"questions":["Question3: "],"instruction":"","echos":[true]}'
+
+read ANSWER3
+
+if test "$ANSWER3" = "answer3"; then
+  echo '{"auth_result":1}'
+else
+  echo '{"auth_result":-1}'
+fi
+```
+
+and here is an example where SFTPGo checks the user password for you:
+
+```shell
+#!/bin/sh
+
+echo '{"questions":["Password: "],"instruction":"This is a sample for keyboard interactive authentication","echos":[false],"check_password":1}'
+
+read ANSWER1
+
+if test "$ANSWER1" != "OK"; then
+  exit 1
+fi
+
+echo '{"questions":["One time token: "],"instruction":"","echos":[false]}'
+
+read ANSWER2
+
+if test "$ANSWER2" = "token"; then
+  echo '{"auth_result":1}'
+else
+  echo '{"auth_result":-1}'
+fi
+```
+
+If the hook is an HTTP URL then it will be invoked as HTTP POST multiple times for each login request.
+The request body will contain a JSON struct with the following fields:
+
+- `request_id`, string. Unique request identifier
+- `username`, string
+- `password`, string. This is the hashed password as stored inside the data provider
+- `answers`, list of string. It will be null for the first request
+- `questions`, list of string. It will contains the previous asked questions. It will be null for the first request
+
+The HTTP response code must be 200 and the body must contain the same JSON struct described for the program.
+
+Let's see a basic sample, the configured hook is `http://127.0.0.1:8000/keyIntHookPwd`, as soon as the user try to login, SFTPGo makes this HTTP POST request:
+
+```shell
+POST /keyIntHookPwd HTTP/1.1
+Host: 127.0.0.1:8000
+User-Agent: Go-http-client/1.1
+Content-Length: 189

+```
+
+as you can see in this first requests `answers` and `questions` are null.
+
+Here is the response that instructs SFTPGo to ask for the user password and to check it:
+
+```shell

+{"questions": ["Password: "], "check_password": 1, "instruction": "This is a sample for keyboard interactive authentication", "echos": [false]}
+```
+
+The user enters the correct password and so SFTPGo makes a new HTTP POST, please note that the `request_id` is the same of the previous request, this time the asked `questions` and the user's `answers` are not null:
+
+```shell

+Content-Length: 66
+
+{"questions": ["Question2: "], "instruction": "", "echos": [true]}
+```
+
+As soon as the user answer to this question, SFTPGo will make a new HTTP POST request with the user's answers:
+
+```shell
+POST /keyIntHookPwd HTTP/1.1

+# Performance
+
+SFTPGo can easily saturate a Gigabit connection on low end hardware with no special configuration, this is generally enough for most use cases.
+
+For Multi-Gig connections, some performance improvements and comparisons with OpenSSH have been discussed [here](https://github.com/drakkan/sftpgo/issues/69), most of them have been included in the master branch. To summarize:
+
+- In current state with all performance improvements applied, SFTP performance is very close to OpenSSH however CPU usage is higher. SCP performance match OpenSSH.
+- The main bottlenecks are the encryption and the messages authentication, so if you can use a fast cipher with implicit messages authentication, such as `aes128-gcm@openssh.com`, you will get a big performance boost.
+- SCP protocol is much simpler than SFTP and so, the multi-platform, SFTPGo's SCP implementation performs better than SFTP.
+- Load balancing with HAProxy can greatly improve the performance if CPU not become the bottleneck.

+# Profiling SFTPGo
+
+The built-in profiler lets you collect CPU profiles, traces, allocations and heap profiles that allow to identify and correct specific bottlenecks.
+You can enable the built-in profiler using the `--profiler` command flag.
+
+Profiling data are exposed via HTTP/HTTPS in the format expected by the [pprof](https://github.com/google/pprof/blob/master/doc/README.md) visualization tool. You can find the index page at the URL `/debug/pprof/`.
+
+The following profiles are available, you can obtain them via HTTP GET requests:
+
+- `allocs`, a sampling of all past memory allocations
+- `block`, stack traces that led to blocking on synchronization primitives
+- `goroutine`, stack traces of all current goroutines
+- `heap`, a sampling of memory allocations of live objects. You can specify the `gc` GET parameter to run GC before taking the heap sample
+- `mutex`, stack traces of holders of contended mutexes
+- `profile`, CPU profile. You can specify the duration in the `seconds` GET parameter. After you get the profile file, use the `go tool pprof` command to investigate the profile
+- `threadcreate`, stack traces that led to the creation of new OS threads
+- `trace`, a trace of execution of the current program. You can specify the duration in the `seconds` GET parameter. After you get the trace file, use the `go tool trace` command to investigate the trace
+
+For example you can:
+
+- download a 30 seconds CPU profile from the URL `/debug/pprof/profile?seconds=30`

+# REST API
+
+SFTPGo exposes REST API to manage, backup, and restore users and folders, and to get real time reports of the active connections with the ability to forcibly close a connection.
+
+If quota tracking is enabled in the configuration file, then the used size and number of files are updated each time a file is added/removed. If files are added/removed not using SFTP/SCP, or if you change `track_quota` from `2` to `1`, you can rescan the users home dir and update the used quota using the REST API.
+
+REST API can be protected using HTTP basic authentication and exposed via HTTPS. If you need more advanced security features, you can setup a reverse proxy using an HTTP Server such as Apache or NGNIX.
+
+For example, you can keep SFTPGo listening on localhost and expose it externally configuring a reverse proxy using Apache HTTP Server this way:
+
+```shell
+ProxyPass /api/v1 http://127.0.0.1:8080/api/v1
+ProxyPassReverse /api/v1 http://127.0.0.1:8080/api/v1
+```
+
+and you can add authentication with something like this:
+
+```shell
+<Location /api/v1>
+  AuthType Digest
+  AuthName "Private"
+  AuthDigestDomain "/api/v1"
+  AuthDigestProvider file
+  AuthUserFile "/etc/httpd/conf/auth_digest"
+  Require valid-user
+</Location>
+```
+
+and, of course, you can configure the web server to use HTTPS.
+
+The OpenAPI 3 schema for the exposed API can be found inside the source tree: [openapi.yaml](../httpd/schema/openapi.yaml "OpenAPI 3 specs").
+
+A sample CLI client for the REST API can be found inside the source tree [rest-api-cli](../examples/rest-api-cli) directory.

+# S3 Compatible Object Storage backends
+
+To connect SFTPGo to AWS, you need to specify credentials, a `bucket` and a `region`. Here is the list of available [AWS regions](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-regions-availability-zones.html#concepts-available-regions). For example, if your bucket is at `Frankfurt`, you have to set the region to `eu-central-1`. You can specify an AWS [storage class](https://docs.aws.amazon.com/AmazonS3/latest/dev/storage-class-intro.html) too. Leave it blank to use the default AWS storage class. An endpoint is required if you are connecting to a Compatible AWS Storage such as [MinIO](https://min.io/).
+
+AWS SDK has different options for credentials. [More Detail](https://docs.aws.amazon.com/sdk-for-go/v1/developer-guide/configuring-sdk.html). We support:
+
+1. Providing [Access Keys](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys).
+2. Use IAM roles for Amazon EC2
+3. Use IAM roles for tasks if your application uses an ECS task definition
+
+So, you need to provide access keys to activate option 1, or leave them blank to use the other ways to specify credentials.
+
+Most S3 backends require HTTPS connections so if you are running SFTPGo as docker image please be sure to uncomment the line that install `ca-certificates`, inside your `Dockerfile`, to be able to properly verify certificate authorities.
+
+Specifying a different `key_prefix`, you can assign different "folders" of the same bucket to different users. This is similar to a chroot directory for local filesystem. Each SFTP/SCP user can only access the assigned folder and its contents. The folder identified by `key_prefix` does not need to be pre-created.
+
+SFTPGo uses multipart uploads and parallel downloads for storing and retrieving files from S3.
+
+For multipart uploads you can customize the parts size and the upload concurrency. Please note that if the upload bandwidth between the SFTP client and SFTPGo is greater than the upload bandwidth between SFTPGo and S3 then the SFTP client have to wait for the upload of the last parts to S3 after it ends the file upload to SFTPGo, and it may time out. Keep this in mind if you customize these parameters.
+
+The configured bucket must exist.
+
+Some SFTP commands don't work over S3:
+
+- `symlink` and `chtimes` will fail
+- `chown` and `chmod` are silently ignored
+- upload resume is not supported
+- upload mode `atomic` is ignored since S3 uploads are already atomic
+
+Other notes:
+
+- `rename` is a two step operation: server-side copy and then deletion. So, it is not atomic as for local filesystem.
+- We don't support renaming non empty directories since we should rename all the contents too and this could take a long time: think about directories with thousands of files; for each file we should do an AWS API call.
+- For server side encryption, you have to configure the mapped bucket to automatically encrypt objects.
+- A local home directory is still required to store temporary files.

+# Running SFTPGo as a service
+
+## Linux
+
+For Linux, a `systemd` sample [service](../init/sftpgo.service "systemd service") can be found inside the source tree.
+
+Here are some basic instructions to run SFTPGo as service, please run the following commands from the directory where you downloaded SFTPGo:
+
+```bash
+# create the required directories
+sudo mkdir -p /etc/sftpgo \
+  /var/lib/sftpgo
+
+# install sftpgo executable
+sudo install -Dm755 sftpgo /usr/bin/sftpgo
+# install the default configuration file, edit it if required
+sudo install -Dm644 sftpgo.json /etc/sftpgo/
+# override some configuration keys using environment variables
+sudo sh -c 'echo "SFTPGO_HTTPD__TEMPLATES_PATH=/var/lib/sftpgo/templates" > /etc/sftpgo/sftpgo.env'

+# optional, install the REST API CLI. It requires python-requests to run
+sudo install -Dm755 examples/rest-api-cli/sftpgo_api_cli.py /usr/bin/sftpgo_api_cli
+```
+
+## macOS
+
+For macOS, a `launchd` sample [service](../init/com.github.drakkan.sftpgo.plist "launchd plist") can be found inside the source tree. The `launchd` plist assumes that SFTPGo has `/usr/local/opt/sftpgo` as base directory.
+
+Here are some basic instructions to run SFTPGo as service, please run the following commands from the directory where you downloaded SFTPGo:
+
+```bash
+# create the required directories
+sudo mkdir -p /usr/local/opt/sftpgo/init \
+  /usr/local/opt/sftpgo/var/lib \
+  /usr/local/opt/sftpgo/var/log \

+sudo /usr/local/opt/sftpgo/bin/sftpgo initprovider -c /usr/local/opt/sftpgo/etc/
+# add sftpgo to the launch daemons
+sudo ln -s /usr/local/opt/sftpgo/init/com.github.drakkan.sftpgo.plist /Library/LaunchDaemons/com.github.drakkan.sftpgo.plist
+# start the service and enable it to start on boot
+sudo launchctl load -w /Library/LaunchDaemons/com.github.drakkan.sftpgo.plist
+# verify that the service is started
+sudo launchctl list com.github.drakkan.sftpgo
+# optional, install the REST API CLI. It requires python-requests to run, this python module is not installed by default
+sudo cp examples/rest-api-cli/sftpgo_api_cli.py /usr/local/opt/sftpgo/bin/
+```
+
+## Windows
+
+On Windows, you can register SFTPGo as Windows Service. Take a look at the CLI usage to learn how to do this:
+
+```powershell
+PS> sftpgo.exe service --help
+Install, Uninstall, Start, Stop, Reload and retrieve status for SFTPGo Windows Service
+
+Usage:
+  sftpgo service [command]
+
+Available Commands:
+  install     Install SFTPGo as Windows Service
+  reload      Reload the SFTPGo Windows Service sending a "paramchange" request
+  rotatelogs  Signal to the running service to close the existing log file and immediately create a new one
+  start       Start SFTPGo Windows Service
+  status      Retrieve the status for the SFTPGo Windows Service
+  stop        Stop SFTPGo Windows Service
+  uninstall   Uninstall SFTPGo Windows Service
+
+Flags:
+  -h, --help   help for service
+
+Use "sftpgo service [command] --help" for more information about a command.
+```
+
+The `install` subcommand accepts the same flags that are valid for `serve`.
+
+After installing as a Windows Service, please remember to allow network access to the SFTPGo executable using something like this:
+
+```powershell
+PS> netsh advfirewall firewall add rule name="SFTPGo Service" dir=in action=allow program="C:\Program Files\SFTPGo\sftpgo.exe"
+```
+
+(Or through the Windows Firewall GUI.)

+# SSH commands
+
+Some SSH commands are implemented directly inside SFTPGo, while for others we use system commands that need to be installed and in your system's `PATH`.
+
+For system commands we have no direct control on file creation/deletion and so there are some limitations:
+
+- we cannot allow them if the target directory contains virtual folders or file extensions filters
+- system commands work only on local filyestem
+- we cannot avoid to leak real filesystem paths
+- quota check is suboptimal
+
+ If quota is enabled and SFTPGO receives a system command, the used size and number of files are checked at the command start and not while new files are created/deleted. While the command is running the number of files is not checked, the remaining size is calculated as the difference between the max allowed quota and the used one, and it is checked against the bytes transferred via SSH. The command is aborted if it uploads more bytes than the remaining allowed size calculated at the command start. Anyway, we only see the bytes that the remote command sends to the local one via SSH. These bytes contain both protocol commands and files, and so the size of the files is different from the size trasferred via SSH: for example, a command can send compressed files, or a protocol command (few bytes) could delete a big file. To mitigate these issues, quotas are recalculated at the command end with a full scan of the directory specified for the system command. This could be heavy for big directories. If you need system commands and quotas you could consider disabling quota restrictions and periodically update quota usage yourself using the REST API.
+
+ For these reasons we should limit system commands usage as much as possibile, we currently support the following system commands:
+
+- `git-receive-pack`, `git-upload-pack`, `git-upload-archive`. These commands enable support for Git repositories over SSH. They need to be installed and in your system's `PATH`.
+- `rsync`. The `rsync` command needs to be installed and in your system's `PATH`. We cannot avoid that rsync creates symlinks, so if the user has the permission to create symlinks, we add the option `--safe-links` to the received rsync command if it is not already set. This should prevent creating symlinks that point outside the home dir. If the user cannot create symlinks, we add the option `--munge-links` if it is not already set. This should make symlinks unusable (but manually recoverable).
+
+SFTPGo support the following built-in SSH commands:
+
+- `scp`, SFTPGo implements the SCP protocol so we can support it for cloud filesystems too and we can avoid the other system commands limitations. SCP between two remote hosts is supported using the `-3` scp option.
+- `md5sum`, `sha1sum`, `sha256sum`, `sha384sum`, `sha512sum`. Useful to check message digests for uploaded files.
+- `cd`, `pwd`. Some SFTP clients do not support the SFTP SSH_FXP_REALPATH packet type, so they use `cd` and `pwd` SSH commands to get the initial directory. Currently `cd` does nothing and `pwd` always returns the `/` path.
+- `sftpgo-copy`. This is a built-in copy implementation. It allows server side copy for files and directories. The first argument is the source file/directory and the second one is the destination file/directory, for example `sftpgo-copy <src> <dst>`. The command will fail if the destination exists. Copy for directories spanning virtual folders is not supported. Only local filesystem is supported: recursive copy for Cloud Storage filesystems requires a new request for every file in any case, so a real server side copy is not possibile.
+- `sftpgo-remove`. This is a built-in remove implementation. It allows to remove single files and to recursively remove directories. The first argument is the file/directory to remove, for example `sftpgo-remove <dst>`. Only local filesystem is supported: recursive remove for Cloud Storage filesystems requires a new request for every file in any case, so a server side remove is not possibile.
+
+The following SSH commands are enabled by default:
+
+- `md5sum`
+- `sha1sum`
+- `cd`
+- `pwd`
+- `scp`

+# Virtual Folders
+
+A virtual folder is a mapping between a SFTP/SCP virtual path and a filesystem path outside the user home directory.
+The specified paths must be absolute and the virtual path cannot be "/", it must be a sub directory.
+The parent directory to the specified virtual path must exist. SFTPGo will try to automatically create any missing parent directory for the configured virtual folders at user login.
+
+For each virtual folder, the following properties can be configured:
+
+- `mapped_path`, the full absolute path to the filesystem path to expose as virtual folder
+- `virtual_path`, the SFTP/SCP absolute path to use to expose the mapped path
+- `quota_size`, maximum size allowed as bytes. 0 means unlimited, -1 included in user quota
+- `quota_files`, maximum number of files allowed. 0 means unlimited, -1 included in user quota
+
+For example if you configure `/tmp/mapped` or `C:\mapped` as mapped path and `/vfolder` as virtual path then SFTP/SCP users can access the mapped path via the `/vfolder` SFTP path.
+
+The same virtual folder, identified by the `mapped_path`, can be shared among users and different folder quota limits for each user are supported.
+Folder quota limits can also be included inside the user quota but in this case the folder is considered "private" and sharing it with other users will break user quota calculation.
+
+You don't need to create virtual folders, inside the data provider, to associate them to the users: any missing virtual folder will be automatically created when you add/update an user. You only have to create the folder on the filesystem.
+
+Using the REST API you can:
+
+- monitor folders quota usage
+- scan quota for folders
+- inspect the relationships among users and folders
+- delete a virtual folder. SFTPGo removes folders from the data provider, no files deletion will occur
+
+If you remove a folder, from the data provider, any users relationships will be cleared up. If the deleted folder is included inside the user quota you need to do a user quota scan to update its quota. An orphan virtual folder will not be automatically deleted since if you add it again later then a quota scan is needed and it could be quite expensive, anyway you can easily list the orphan folders using the REST API and delete them if they are not needed anymore.
+
+Overlapping virtual paths are not allowed for the same user, overlapping mapped paths are allowed only if quota tracking is globally disabled inside the configuration file (`track_quota` must be set to `0`).
+Virtual folders are supported for local filesystem only.

+# Web Admin
+
+You can easily build your own interface using the exposed REST API. Anyway, SFTPGo also provides a very basic built-in web interface that allows you to manage users and connections.
+With the default `httpd` configuration, the web admin is available at the following URL:
+
+[http://127.0.0.1:8080/web](http://127.0.0.1:8080/web)
+
+The web interface can be protected using HTTP basic authentication and exposed via HTTPS. If you need more advanced security features, you can setup a reverse proxy as explained for the [REST API](./rest-api.md).

-# Authy
-
-These example show how-to integrate [Twilio Authy API](https://www.twilio.com/docs/authy/api) for One-Time-Password logins.
-
-The examples assume that the user has the free [Authy app](https://authy.com/) installed and uses it to generate offline [TOTP](https://en.wikipedia.org/wiki/Time-based_One-time_Password_algorithm) codes (soft tokens).
-
-You first need to [create an Authy Application in the Twilio Console](https://twilio.com/console/authy/applications?_ga=2.205553366.451688189.1597667213-1526360003.1597667213), then you can create a new Authy user and store a reference to the matching SFTPGo account.
-
-Verify that your Authy application is successfully registered:
-
-```bash
-export AUTHY_API_KEY=<your api key here>
-curl 'https://api.authy.com/protected/json/app/details' -H "X-Authy-API-Key: $AUTHY_API_KEY"
-```
-
-now create an Authy user:
-
-```bash
-curl -XPOST "https://api.authy.com/protected/json/users/new" \
--H "X-Authy-API-Key: $AUTHY_API_KEY" \
---data-urlencode user[email]="user@domain.com" \
---data-urlencode user[cellphone]="317-338-9302" \
---data-urlencode user[country_code]="54"
-```
-
-The response is something like this:
-
-```json
-{"message":"User created successfully.","user":{"id":xxxxxxxx},"success":true}
-```
-
-Save the user id somewhere and add a reference to the matching SFTPGo account. You could also store this ID in the `additional_info` SFTPGo user field.
-
-After this step you can use the Authy app installed on your phone to generate TOTP codes.
-
-Now you can verify the token using an HTTP GET request:
-
-```bash
-export TOKEN=<TOTP you read from Authy app>
-export AUTHY_ID=<user id>
-curl -i "https://api.authy.com/protected/json/verify/${TOKEN}/${AUTHY_ID}" \
-    -H "X-Authy-API-Key: $AUTHY_API_KEY"
-```
-
-So inside your hook you need to check:
-
-- the HTTP response code for the verify request, it must be `200`
-- the JSON response body, it must contains the key `success` with the value `true` (as string)
-
-If these conditions are met the token is valid and you allow the user to login.
-
-We provide the following examples:
-
-- [Keyboard interactive authentication](./keyint/README.md) for 2FA using password + Authy one time token.
-- [External authentication](./extauth/README.md) using Authy one time tokens as passwords.
-- [Check password hook](./checkpwd/README.md) for 2FA using a password consisting of a fixed string and a One Time Token.
-
-Please note that these are sample programs not intended for production use, you should write your own hook based on them and you should prefer HTTP based hooks if performance is a concern.
-
-:warning: SFTPGo has also built-in 2FA support.

-# Import users from other stores
-
-`convertusers` is a very simple command line client, written in python, to import users from other stores. It requires `python3` or `python2`.
-
-Here is the usage:
-
-```console
-usage: convertusers [-h] [--min-uid MIN_UID] [--max-uid MAX_UID] [--usernames USERNAMES [USERNAMES ...]]
-                    [--force-uid FORCE_UID] [--force-gid FORCE_GID]
-                    input_file {unix-passwd,pure-ftpd,proftpd} output_file
-
-Convert users to a JSON format suitable to use with loadddata
-
-positional arguments:
-  input_file
-  {unix-passwd,pure-ftpd,proftpd}
-                        To import from unix-passwd format you need the permission to read /etc/shadow that is typically
-                        granted to the root user only
-  output_file
-
-optional arguments:
-  -h, --help            show this help message and exit
-  --min-uid MIN_UID     if >= 0 only import users with UID greater or equal to this value. Default: -1
-  --max-uid MAX_UID     if >= 0 only import users with UID lesser or equal to this value. Default: -1
-  --usernames USERNAMES [USERNAMES ...]
-                        Only import users with these usernames. Default: []
-  --force-uid FORCE_UID
-                        if >= 0 the imported users will have this UID in SFTPGo. Default: -1
-  --force-gid FORCE_GID
-                        if >= 0 the imported users will have this GID in SFTPGo. Default: -1
-```
-
-Let's see some examples:
-
-```console
-python convertusers "" unix-passwd unix_users.json --min-uid 500 --force-uid 1000 --force-gid 1000
-```
-
-```console
-python convertusers pureftpd.passwd pure-ftpd pure_users.json --usernames "user1" "user2"
-```
-
-```console
-python convertusers proftpd.passwd proftpd pro_users.json
-```
-
-The generated json file can be used as input for the `loaddata` REST API.
-
-Please note that when importing Linux/Unix users the input file is not required: `/etc/passwd` and `/etc/shadow` are automatically parsed. `/etc/shadow` read permission is typically granted to the `root` user only, so you need to execute `convertusers` as `root`.
-
-:warning: SFTPGo does not currently support `yescrypt` hashed passwords.
