Andrea Maria Piana 23f71c1125 Fix encryption id && rekey with a single message ... This commit changes the format of the encryption id to be based off 3 things: 1) The group id 2) The timestamp 3) The actual key Previously this was solely based on the timestamp and the group id, but this might lead to conflicts. Moreover the format of the key was an uint32 and so it would wrap periodically. The migration is a bit tricky, so first we cleared the cache of keys, that's easier than migrating, and second we set the new field hash_id to the concatenation of group_id / key_id. This might lead on some duplication in case keys are re-received, but it should not have an impact on the correctness of the code. I have added 2 tests covering compatibility between old/new clients, as this should not be a breaking change. It also adds a new message to rekey in a single go, instead of having to send multiple messages		2023-10-24 20:48:54 +01:00
