2020-08-31allow some things to be Uint8Array, and fix some TypeScript declarationsHubert Chathi
2019-10-04Pass in a buffer to olm_session_describeDavid 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.
2019-10-01Add olm_session_describeDavid 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.
2019-04-08re-add null termination in javascriptHubert Chathi
because older versions of emscripten don't support the length argument to UTF8ToString.
2019-04-08javascript: Switch from deprecated Pointer_stringify() to UTF8toString().Damir Jelić
The Pointer_stringify() function is deprecated and has a couple of issues because it tries to guess the encoding of the buffer. In some cases it can ignore the length parameter which could end up in inconsistencies. Switch to UTF8toString() that takes a length parameter and respects, that way we don't need to allocate an additional byte for a NULL byte.

2018-10-04Dual-build wasm and asm.js olmDavid Baker
2018-09-25Another day, another interfaceDavid Baker
Change the interface again, hopefully this time a bit more normal. Now we wrap the emscripten module completely and just expose the high level objects. The olm library export is now imported as normal (ie. returns a module rather than a function returning a module) but has an `init` method which *must* be called. This returns a promise which resolves when the module is ready. It also rejects if the module failed to set up, unlike before (and unlike the promise-not-a-promise that emscripten returns). Generally catch failures to init the module.
2018-09-21WebAssembly support!David Baker
Quite a lot going on in this PR: * Updates to support recent emscripten, switching to WASM which is now the default * Use emscripten's MODULARIZE option rather than wrapping it ourself, since doing so in pre-post js doesn't work anymore. * Most changes are moving the emscripten runtime functions to top-level calls rather than in the Module object. * Get rid of duplicated NULL_BYTE_PADDING_LENGTH * Fix ciphertext_length used without being declared * Fix things that caused the closure compiler to error, eg. using OLM_OPTIONS without a declaration. * Wait until module is inited to do OLM_ERROR = olm_error() The main BREAKING CHANGE here is that the module now needs to initialise asyncronously (because it has to load the wasm file). require()ing olm now gives a function which needs to be called to create an instance. The resulting object has a promise-like then() method that can be used to detect when the module is ready. (We could use MODULARIZE_INSTANCE to return the module directly as before, rather than the function, but then we don't get the .then() method).

2016-12-16Avoid buffer overrun on encryptionRichard van der Hoff
Make sure we null-terminate encrypted strings before passing them to UTF8ToString. This used to work when we allocated the buffer on the stack, because it turns out that allocate() zeroinits the returned memory. malloc(), of course, does not.

Allocate memory for message blobs on the heap

2016-12-15zero out plaintext buffersRichard van der Hoff
Avoid leaving copies of the plaintext sitting around in the emscripten heap.
2016-12-14Allocate memory for message blobs on the heapRichard van der Hoff
Messages can be very large, so we don't really want to allocate them on the stack. Switch to using the heap for them, and try to clean up some of the string handling while we're at it.
2016-12-12Better handling of exceptions during loadingRichard van der Hoff
If we get an exception during load, don't define half of window.Olm (which confuses apps). This is a partial fix to https://github.com/vector-im/riot-web/issues/2726.

2016-09-05Fix megolm decryption of UTF-8Richard van der Hoff
Repeat the fix from b10f90d for megolm messages. It turns out that the 'length' argument to 'Pointer_stringify' doesn't work if the input includes characters >= 128. Rather than try to figure out which methods can return UTF-8, and which always return plain ascii, replace all uses of Pointer_stringify with a 'length' argument with the version that expects a NULL-terminated input, and extend the buffer by a byte to allow space for a null-terminator. In the case of decrypt, we need to add the null ourself. Fixes https://github.com/vector-im/vector-web/issues/2078.
2016-09-04OlmSession.has_received_messageRichard 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.
2016-09-01Fix 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.
