libolm - Implementation of the olm and megolm cryptographic ratchets

Age	Commit message (Collapse)	Author
2016-09-06	Sign megolm messages	Richard van der Hoff
	Add ed25519 keys to the inbound and outbound sessions, and use them to sign and verify megolm messages. We just stuff the ed25519 public key in alongside the megolm session key (and add a version byte), to save adding more boilerplate to the JS/python/etc layers.
2016-05-25	Remove session_id from group messages	Richard van der Hoff
	Putting the session_id inside the packed message body makes it hard to extract so that we can decide which session to use. We don't think there is any advantage to having thes sesion_id protected by the HMACs, so we're going to move it to the JSON framing.
2016-05-24	Separate base64ing from the rest of msg encoding	Richard van der Hoff
	Factor the actual message encoding/decoding and encrypting/decrypting out to separate functions from the top-level functions which do the base64-wrangling. This is particularly helpful in the 'outbound' code-path where the offsets required to allow room to base64-encode make the flow hard to see when it's all inline.
2016-05-24	Fix up some names, and protobuf tags	Richard van der Hoff
	Make names (of session_key and message_index) more consistent. Use our own protobuf tags rather than trying to piggyback on the one-to-one structure.
2016-05-24	Implement decrypting inbound group messages	Richard van der Hoff
	Includes creation of inbound sessions, etc
