Age	Commit message (Collapse)	Author
2020-09-23	set their_key_set flag explicitly on init	Hubert Chathi

2020-09-23	SAS: add olm_sas_is_their_key_set	Saúl Ibarra Corretgé
	Also make olm_sas_generate_bytes fail if their key wasn't set.
2020-09-16	fix style	Hubert Chathi

2020-08-14	add support for fallback keys	Hubert Chathi

2019-10-08	check return value of snprintf, fix typo, add clarification	Hubert Chathi

2019-10-04	Pass in a buffer to olm_session_describe	David Baker
	instead of having a static one, as that could end up taking up a lot of memory if your app keeps olm sessions hanging about.
2019-10-01	Add olm_session_describe	David Baker
	As a way to dump the state of an olm session, ie. the chain indicies, so we can debug why olm sessions break and get out of sync.
2019-05-14	add more consts and comments	Hubert Chathi

2019-05-14	add comment about input buffers being overwritten	Hubert Chathi
	also make some params const where possible

2019-03-13	rename functions to be more consistent	Hubert Chathi

2019-02-01	call the right function and remove unnecessary include	Hubert Chathi

2019-01-29	Add signing class to the pk module	David Baker

2019-01-21	initial implementation of short authentication string generation	Hubert Chathi

2018-10-15	use the correct error code	Hubert Chathi

2018-10-11	Add aliases for deprecated functions	David Baker

2018-10-05	Merge branch 'master' into dbkr/pk_private_export_import	Hubert Chathi

2018-10-05	fix some code style issues and typos	Hubert Chathi

2018-10-02	Work with PkDecryption keys by their private keys	David Baker
	Change interface to allow the app to get the private part of the key and instantiate a decryption object from just the private part of the key. Changes the function generating a key from random bytes to be initialising a key with a private key (because it's exactly the same thing). Exports & imports private key parts as ArrayBuffer at JS level rather than base64 assuming we are moving that way in general.
2018-09-19	Fix output buffer length check	David Baker
	...when generating a key in PkDecryption. The pubkey is base64ed on the output, so will be longer.
2018-06-28	use void in type signatures for functions with no arguments	Hubert Chathi

2018-06-28	add functions for pickling/unpickling a decryption object	Hubert Chathi

2018-06-27	add initial implementation of basic private key encryption functionality	Hubert Chathi

2018-06-27	Fix warnings reported by LLVM	manuroe

2018-06-27	fix a length check and add some missing length checks	Hubert Chathi

2017-09-29	Drop unused #include	Alexey Rusakov
	Signed-off-by: Alexey Rusakov <ktirf@users.sf.net>
2017-09-29	Avoid C99 inside C++ code	Alexey Rusakov
	This disrupts building at least with Visual Studio. Signed-off-by: Alexey Rusakov <ktirf@users.sf.net>
2017-01-10	Add some tests for inbound session import/export	Richard van der Hoff

2017-01-10	Store a flag indicating if the sender key is verified	Richard van der Hoff

2017-01-09	Implement importing group session data	Richard van der Hoff
	olm_import_inbound_group_session, which reads the format written by olm_export_inbound_group_session to initialise a group session.
2017-01-06	Enable exporting inbound group session keys	Richard van der Hoff
	A pair of functions which allow you to export the megolm keys for an inbound group session, so that an application can save/restore them.
2016-10-24	Return the base64-encoded length of pickles	Richard van der Hoff
	make olm_pickle_* return the lengths of the base64-encoded pickles, rather than the raw pickle. (From the application's POV, the format of the pickle is opaque: it doesn't even know that it is base64-encoded. So returning the length of the raw pickle is particularly unhelpful.)
2016-10-21	Clear random buf in olm_init_outbound_group_session	Richard van der Hoff
	All the other methods clear their random inputs. This one needs to do the same, to reduce the risk of the randomness being used elsewhere and leaking key info.
2016-10-21	Merge pull request #31 from matrix-org/markjh/groupmessageindex	Mark Haines
	Return the message index when decrypting group messages.
2016-10-20	Add NULL check for message_index pointer	Mark Haines

2016-10-20	Return the message index when decrypting group messages.	Mark Haines
	Applications can use the index to detect replays of the same message.
2016-10-19	Fix a buffer bounds check when decoding group messages	Richard van der Hoff
	Fixes a segfault when a group message had exactly the length of the mac + signature. Also tweak skipping of unknown tags to avoid an extra trip around the loop.
2016-09-13	Merge pull request #23 from matrix-org/markjh/remove_message_index	Mark Haines
	Remove the messsage index from olm_init_inbound_group_session
2016-09-13	Remove the messsage index from olm_init_inbound_group_session since it is ↵	Mark Haines
	read from the session_key
2016-09-13	Add a olm_inbound_group_session_id method	Mark Haines

2016-09-13	``if`` is not the same as ``for``	Mark Haines

2016-09-13	Comment on the encoding of the message counter.	Mark Haines

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 pickling functions to C	Richard van der Hoff
	... so that I can use them from the group session bits.
2016-09-05	Convert AES functions to plain C	Richard van der Hoff

2016-09-05	Convert Ed25519 and Curve25519 functions to plain C	Richard van der Hoff

2016-09-05	Merge pull request #15 from matrix-org/rav/has_received_message	Richard van der Hoff
	OlmSession.has_received_message
2016-09-04	OlmSession.has_received_message	Richard van der Hoff
	I find myself wanting to know if an OlmSession is in the pre-key state or not, to help debugging at the application level.
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).
