2016-06-30Remove unused 'chain_index' from RatchetRichard 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.
2016-05-25Remove session_id from group messagesRichard 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.
2016-05-24Separate base64ing from the rest of msg encodingRichard 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.
2016-05-24Update megolm_cipher as a global structRichard van der Hoff
Initialise megolm_cipher via the preprocessor macro, instead of with a function.
2016-05-24Fix up some names, and protobuf tagsRichard 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.
2016-05-24Implement decrypting inbound group messagesRichard van der Hoff
Includes creation of inbound sessions, etc
2016-05-24Implement functions to get the state of outbound sessionRichard van der Hoff
We need to be able to inspect an outbound session so that we can tell our peer how to set up an inbound session.
2016-05-24Implement pickling/unpickling for outbound group sessionsRichard van der Hoff
2016-05-24Implementation of an outbound group sessionRichard van der Hoff
2016-05-24Implementation of the megolm ratchetRichard van der Hoff
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
2016-05-24Remove 'destruct' from cipher_opsRichard van der Hoff
We never delete a cipher, and the destruct op is empty, so it's a bit pointless
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.
2016-05-23C bindings for base64 functionsRichard van der Hoff
2016-05-23C binding for olm::unsetRichard van der Hoff
2016-05-23C bindings for pickle functionsRichard van der Hoff

2016-05-23Convert error.hh to plain CRichard van der Hoff
2016-05-23Give SHA256 functions C bindingsRichard van der Hoff
2016-05-23Rename olm.hh to olm.hRichard van der Hoff
2016-05-20Remove functions which return stringsRichard van der Hoff
We don't want anything which does dynamic memory allocation in the library.
2016-05-16Remove vestiges of loggingRichard van der Hoff
Remove the (now non-functional) declarations of olm_set_log_level in the C and js wrappers.
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.
