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.
2016-05-24Factor out pickle_encoding from olm.cppRichard van der Hoff
We don't need to have all of the top-level pickling functions in olm.cpp; factor out the utilities to support it to pickle_encoding.cpp (and make sure that they have plain-C bindings).
2016-05-24Factor out olm_error_to_string to a separate fileRichard van der Hoff
I want to be able to use this functionality from elsewhere, so factor it out to its own file.
2016-05-24Rewrite _olm_cipher_aes_sha_256 initialisationRichard van der Hoff
Replace the init-static-var dance with some preprocessor macros
2016-05-23Prefix for internal symbolsRichard van der Hoff
Give a load of internal symbols "_olm_" prefixes. This better delineates the public and private interfaces in the module, and helps avoid internal symbols leaking out and possibly being abused.

Should have been in the previous commit :/
2016-05-23fix range check in olm_*_last_errrorRichard van der Hoff
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.
