libolm - Implementation of the olm and megolm cryptographic ratchets

Age	Commit message (Collapse)	Author
2016-05-25	Add a comment explaining Mark's latest fix	Richard van der Hoff

2016-05-25	Fix an integer wrap around bug and add a couple more tests	Mark Haines

2016-05-24	Fix handling of integer wraparound in megolm.c	Richard van der Hoff

2016-05-24	megolm_advance_to: Remove excessive optimisation	Richard van der Hoff
	There was some slightly overcomplex logic designed to save a couple of hash operations when R(0) and R(1) were advanced, but the extra code was hard to understand and didn't save much.
2016-05-24	megolm.c: rewrite counter update	Richard van der Hoff
	We no longer need to keep track of intermediate values of the counter, which means we can update it much more easily.
2016-05-24	megolm.c: Remove spurious arguments to rehash_part	Richard van der Hoff
	These were left over from when rehash_part did a bunch of logging.
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	Update megolm_cipher as a global struct	Richard van der Hoff
	Initialise megolm_cipher via the preprocessor macro, instead of with a function.
2016-05-24	Use _olm_unset instead of memset	Richard van der Hoff
	memset is at risk of being optimised away, so use _olm_unset instead.
2016-05-24	Avoid relying on uint -> int casting behaviour	Richard van der Hoff
	The behaviour when casting from a uint32_t which has overflowed (so has the top bit set) to int32_t is implementation-defined, so let's avoid relying on it.
2016-05-24	Python wrapper: support for inbound group sessions	Richard van der Hoff

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	Support for pickling inbound group sessions	Richard van der Hoff

2016-05-24	Implement decrypting inbound group messages	Richard van der Hoff
	Includes creation of inbound sessions, etc
2016-05-24	Implement functions to get the state of outbound session	Richard 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.
2016-05-24	Outbound group session support in the python wrappers	Richard van der Hoff

2016-05-24	Implement pickling/unpickling for outbound group sessions	Richard van der Hoff

2016-05-24	Implementation of an outbound group session	Richard van der Hoff

2016-05-24	Implementation of the megolm ratchet	Richard van der Hoff

2016-05-24	Factor out pickle_encoding from olm.cpp	Richard 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).
2016-05-24	Factor out olm_error_to_string to a separate file	Richard van der Hoff
	I want to be able to use this functionality from elsewhere, so factor it out to its own file.
2016-05-24	Merge branch 'rav/c_bindings'	Richard van der Hoff

2016-05-24	Rewrite _olm_cipher_aes_sha_256 initialisation	Richard van der Hoff
	Replace the init-static-var dance with some preprocessor macros
2016-05-24	Remove 'destruct' from cipher_ops	Richard van der Hoff
	We never delete a cipher, and the destruct op is empty, so it's a bit pointless
2016-05-23	Fix bug in bounds check when parsing	Mark Haines

2016-05-23	Prefix for internal symbols	Richard 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.
2016-05-23	C bindings for base64 functions	Richard van der Hoff

2016-05-23	C binding for olm::unset	Richard van der Hoff

2016-05-23	C bindings for pickle functions	Richard van der Hoff

2016-05-23	Convert cipher.hh to plain C	Richard van der Hoff

2016-05-23	Convert error.hh to plain C	Richard van der Hoff

2016-05-23	Give SHA256 functions C bindings	Richard van der Hoff

2016-05-23	Rename olm.hh to olm.h	Richard van der Hoff

2016-05-23	Complete fixes for olm_*_last_error	Richard van der Hoff
	Should have been in the previous commit :/
2016-05-23	fix range check in olm_*_last_errror	Richard van der Hoff

2016-05-23	Fix warnings and set -Werror	Richard van der Hoff

2016-05-23	Merge branch 'rav/refactor_python_wrappers'	Richard van der Hoff

2016-05-23	Fix make clean to remove the library and all the .d files	Mark Haines

2016-05-23	Move comment to correct location	Mark Haines

2016-05-23	Don't use $^ cause that includes the header files	Mark Haines

2016-05-23	Use a rule to make the build directories	Mark Haines

2016-05-23	Put the .o files in separate directories so we can have both release and ↵	Mark Haines
	debug versions
2016-05-20	Fix the Makefile so that it works with a clean git checkout	Mark Haines

2016-05-20	Merge branch 'rav/makefile'	Richard van der Hoff

2016-05-20	Remove dep files for js objects on clean	Richard van der Hoff

2016-05-20	crypto.cpp: Fix comments	Richard van der Hoff
	These seem to be the wrong way around.
2016-05-20	Add an 'all' target to the Makefile	Richard van der Hoff
	So that we can build everything together.
2016-05-20	Refactor python wrappers	Richard van der Hoff
	Split the python wrappers into separate modules
2016-05-20	Use a version script to restrict symbols in the .so	Richard van der Hoff
	We want to stop aes_* and sha_* functions leaking out of our .so, as well as internal _olm_* symbols. This also means we need to link the unit tests against the objects. Possibly we should distinguish between unit tests and integration tests.
2016-05-20	Add support for building the JS wrappers to the Makefile	Richard van der Hoff
	Now that we have C and C++, we need to split the compile and link steps (because we need different flags for the C and C++ files), so this is easier with a Makefile.
