2016-09-05Convert ed25519 pickling functions to CRichard van der Hoff
... so that I can use them from the group session bits.
2016-09-05Convert Ed25519 and Curve25519 functions to plain CRichard van der Hoff
2016-09-02Create new constants for key lengths, etcRichard 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).
2016-09-01Fix Ed25519 keypair generationRichard 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.

2016-05-16Remove logging functionalityRichard van der Hoff
Concerns have been raised that including logging functionality makes it harder to audit the implementation to ensure that no secret information is leaked. We are therefore removing it from the master branch.
