noise/builder.py:
- Added guard for data length in decrypt
- Handling InvalidTag exception when AEAD fails
- New NoiseInvalidMessage exception class
noise/exceptions.py
- Three new exception classes
noise/noise_protocol.py
- Implemented rest of validation, now checks for required keypairs, setting initiator/responder role, warns if ephemeral keypairs are set.
noise/patterns.py:
- added name field to every Pattern with pattern name
- added get_required_keypairs method that returns list of keypairs required for given handshake pattern
noise/state.py
- new NoiseMaxNonceError exception
Overall: some TODOs resolved
noise/__init__.py
- __all__ containing builder module
noise/builder.py
- NoiseBuilder class providing interface for use with other apps. Allows
for setting up all required data for Noise protocol, using appropriate
methods. Enforces proper path of handshake execution
noise/constants.py
- Added maximum Noise message length constant
noise/exceptions.py
- A few exceptions created for proper signaling of errors
noise/noise_protocol.py
- handshake_done does proper cleanup now
- new validation method that should be ran before starting handshake
(checks presence of prerequisites for current settings)
- new HandshakeState initialization method
noise/state.py
- Modified read_message and write_message methods of HandshakeState to
operate on bytes/bytearray as message/payload and bytearray as
message_buffer/payload_buffer. It is application's responsibility to
provide data in this form, underlying Noise code doesn't do buffer
reading/writing anymore.
tests/test_vectors.py
- Changed tests to comply with new code
