Checksum
|
||||
========
|
||||
|
||||
**Plugin for [Nextcloud](https://nextcloud.com) and [ownCloud](https://owncloud.org) to create hashes of files.**
|
||||
**App for [Nextcloud](https://nextcloud.com) to print files using the CUPS/LPR printing ecosystem.**

Installation
|
||||
------------
|
||||
|
||||
**Nextcloud**
|
||||
|
||||
In your Instance, simply navigate to »Apps«, choose the category »Files«, find the Checksum app and enable it.
|
||||
You need a working CUPS setup with a compatible printer set up as the default printer and the LPR daemon installed on your server.
|
||||
|
||||
**ownCloud**
|
||||
- Copy the checksum folder in the app directory of owncloud.
|
||||
- If not already done, rename the app-folder to "checksum" - causes overwise an sql error.
|
||||
- Enable this app in the admin interface.
|
||||
In your Instance, simply navigate to »Apps«, choose the category »Tools«, find the Printer app and enable it.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
Just open the details view of the file (Sidebar). There should be a new tab called "Checksum". Select a algorithm and it will try to generate a hash. If you want an other algorithm, just click on the reload button.
|
||||
Just open the details view of the file (Sidebar). There should be a new tab called "Printer". Select a Orientation of your print and it will try to ececute the LPR (Line Printing Daemon) on the CLI to send the job to a printer configured in CUPS. Currently, only the printer set as default can be used for printing.
|
||||
|
||||
Possible algorithms are md5, sha1, sha256, sha384, sha512 and crc32.
|
||||
Possible orientations are "Landscape" and "Portrait". Further options will be added in the future.
|
||||
|
||||
Compatibility
|
||||
-------------
|
||||
|
||||
- I only tested the app for the current version of owncloud (9.x) and Nextcloud 10 and 11.
|
||||
- I only tested the app for the current versions of Nextcloud (14 and up).
|
||||
- I tried to use the current api as much as possible. It should be safe for future versions.
|
||||
- Currently only files supported by CUPS natively are supported for printing. This includes Images, PDFs, text files and probably others. Not all filetypes are supported by CUPS.
|
||||
- The app currently misses a lot of features that will be added in future versions of the app. If you want to help out with development, a PR is highly welcome.
