2019-06-19_compat: Change the to_native_str into a to_unicode_str function.Damir Jelić
The to_native_str function was supposed to produce Unicode decoded native strings for python2 and python3. Upon further consideration this doesn't make much sense since under python2 it would need to decode the bytes into a Unicode string and turn it back into a python2 str. The ability to use the replacement character requires us to use a Unicode string under python2 as well.
2019-06-19_compat: Remove unused import.Damir Jelić
2019-06-18olm: Allow decryption functions to define how to handle unicode decode errors.Damir Jelić
This patch changes the decryption functions not to fail if there was an unicode decode error while converting the decrypted bytes plaintext into a native python string. Characters that cannot be decoded as unicode are now replaced with the unicode replacement character (U+FFFD). The old behaviour of raising an UnicodeDecodeError can be achieved by passing the "strict" error handling scheme to the decrypt function.

2018-07-18python: Import improved python bindings.Damir Jelić
This commit imports the python bindings from: https://github.com/poljar/python-olm The bindings are imported at commit c44b145818520d69eaaa350fb95afcb846125e0f Minor modifications were made while importing: - Removed travis config - Removed Arch Linux PKGBUILD - Removed the html docs, they can be rebuild by running make html in the docs folder - Slightly modified the README The new bindings feature some improvements over the old ones: - Python 2 and 3 support - Automatic memory management - Automatic memory clearing before it is freed - Type signatures via the python typing module - Full test coverage - Properties are utilized where it makes sense (e.g. account.id) Signed-off-by: Damir Jelić <poljar@termina.org.uk>

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.
