Nick Mills-Barrett	15ab545e72	crypto: add background context to olm machine ... Defaults to `context.Background()` but can be passed any context to support cancelling background jobs the olm instance might be executing.	2024-12-16 15:45:57 +00:00

Tulir Asokan	3bd42f5a82	Add option to disable tracking megolm session ratchet state ... The tracking is meant for bridges/bots that want to delete old ratchet states after they're not needed, but for normal clients it's just unnecessary overhead	2024-05-16 17:14:13 +03:00
Sumner Evans	de0347db00	crypto: fix usages of Store interface ... Signed-off-by: Sumner Evans <sumner.evans@automattic.com>	2024-05-14 12:47:45 -06:00
Sumner Evans	d10103dcf5	crypto/encryptmegolm: return error if sharing outbound session fails ... This allows us to catch and throw "database is locked" errors. This will ensure that if saving the key fails, then we won't share the key out to anyone. Signed-off-by: Sumner Evans <sumner.evans@automattic.com>	2024-05-13 21:47:45 -06:00
Sumner Evans	ff9e2e0f1d	machine/ShareKeys: save keys before sending server request in case it fails ... Signed-off-by: Sumner Evans <sumner@beeper.com>	2024-04-19 08:47:36 -06:00
Toni Spets	bb6c88faf3	Add callback on megolm session receive	2024-03-06 15:06:21 +02:00

Toni Spets	11c2907f2e	Database level support for key backup versioning ... This doesn't plumb anything in yet but adds the columns and types for an external implementation. Key backup version is now typed.	2024-02-01 13:22:32 +02:00
Toni Spets	8dc80b3178	Share room keys to known devices on request ... If we have shared a session with a device once, allow asking for it again.	2024-01-26 13:52:25 +02:00

Toni Spets	6ac759c8ff	Only skip fetching keys during Megolm decryption if disabled ... Blanket disabling caused a lot of side effects which were hard to deal with without major refactoring. This should probably be an argument to DecryptMegolm instead of a flag.	2024-01-17 12:15:21 +02:00

Toni Spets	a3883fcf6f	Allow disabling automatic key fetching for Olm machine ... Many crypto operations in the Olm machine have a possible side effect of fetching keys from the server if they are missing. This may be undesired in some special cases. To tracking which users need key fetching, CryptoStore now exposes APIs to mark and query the status.	2024-01-12 14:12:47 +02:00
Toni Spets	8da3a17402	Add context to OLM machine LoadDevices ... As there's a side effect of going to the crypto store we want the context to at least exist for now.	2024-01-10 13:25:44 +02:00
