| 2016-09-13 | Use the ed22519 public key as the group session id. | Mark Haines | |
| Some clients expect the session id to be globally unique, so allowing the end devices to pick the session id will cause problems. Include the current ratchet index with the initial keys, this decreases the risk that the client will supply the wrong index causing problems. Sign the initial keys with the ratchet ed25519 key, this reduces the risk of a client claiming a session that they didn't create. | |||
| 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. | |||

| 2016-09-05 | Convert Ed25519 and Curve25519 functions to plain C | Richard van der Hoff | |
| 2016-09-02 | Create new constants for key lengths, etc | Richard van der Hoff | |
| We were using olm::KEY_LENGTH for everything under the sun which happened to be 32 bytes long, and making a bunch of assumptions in the process. Create a bunch of new constants (as C #defines rather than C++ consts so that I can use them in another forthcoming refactor). | |||
| 2016-09-01 | Fix Ed25519 keypair generation | Richard van der Hoff | |
| Ed25519 private keys, it turns out, have 64 bytes, not 32. We were previously generating only 32 bytes (which is all that is required to generate the public key), and then using the public key as the upper 32 bytes when generating the per-message session key. This meant that everything appeared to work, but the security of the private key was severely compromised. By way of fixes: * Use the correct algorithm for generating the Ed25519 private key, and store all 512 bits of it. * Update the account pickle format and refuse to load the old format (since we should consider it compromised). * Bump the library version, and add a function to retrieve the library version, so that applications can verify that they are linked against a fixed version of the library. * Remove the curve25519_{sign, verify} functions which were unused and of dubious quality. | |||

| * write V1 pickles on the master branch * the logging branch is going to write v0x80000001 | |||
| 2016-06-30 | Make space in the session pickle for chain index | Richard van der Hoff | |
| Keeping track of the chain index is a useful thing to do, but is only required if we've enabled diagnostics. Extend the session pickle format to make a space for it, so that pickles can be transferred between the logging_enabled branch and the master branch without loss of information. Also add some tests for session pickling which explicitly check that we can unpickle both formats of pickle. | |||
| 2016-06-30 | Remove unused 'chain_index' from Ratchet | Richard van der Hoff | |
| This was introduced when I was experimenting with support for logging progress in Olm. That is now relegated to the logging_enabled branch, so this should probably be removed. This also fixes the incompatibility of session pickles from the current master branch with those from olm 0.1.0. | |||
| 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 | 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. | |||
