* Created NoiseBackend class serving as a base for backends
* Refactored NoiseProtocol name parsing
* Refactored existing spec-defined functions into abstract classes.
Implementing classes are connecting crypto primitives to expected
interfaces.
* Refactored existing usage of Cryptography as source of crypto into
"default" backend (along with in-house implementation of X448).
* Provisioned "experimental" backend, it will contain e.g. non-default
crypto algorithms
* Backend can be chosen while creating NoiseConnection, though by
default, the Cryptography backend ("default") is used
Closes#7
scapy-python3 is an unofficial fork that is getting very oudated (many bug fixes missing).
Migrates to original and up-to-date scapy, which now supports both python 2 and 3
According to PEP440, a comma in a version specifier behaves as a logical AND,
so the previous "~=3.5,~=3.6" is equivalent to just "~=3.6", which excludes
python3.5.
This patch replaces it with "~=3.5", which is equivalent to ">=3.5, ==3.*",
so it includes 3.5, 3.6, 3.7, and beyond (but not 4.0).
* Allowed '/' in protocol name
* Added SymmetricState.GetHandshakeHash()
* Added CipherState.SetNonce()
* Unittests to ensure that each of above is working
Closes#3
* 2.1 version of pyca/cryptography got released. Version bumped
* Python 3.5 support reintroduced, as we are now using BLAKE from
Cryptography, not hashlib
* Removed hashlib references, uncommented Cryptography references.
* Enum fix for python 3.5 compat
Closes#9
First shot at documentation. Just to check if they work with
ReadTheDocs.
Also, added dev_requirements.txt with packages required for development
of package.
Refs #8
- Added readme
- Updated setup.py
- Removed pytest from requirements, added version of cryptography
package
- Small improvements in code:
noise/noise_protocol.py:
* removed unused one_way variable
noise/patterns.py
* fixed has_pre_messages - no longer a variable, but method - and now
works properly
noise/state.py
* SymmetricState now holds reference to CipherState.
tests/vectors/*:
- removed noise-c-basic.txt test vectors
tests/test_vectors.py:
- removed workarounds related to noise-c test vectors
noise/builder.py:
- added some more type hinting
noise/state.py:
- CipherState is now consistent in raising NoiseMaxNonceError
and using MAX_NONCE constant for encrypt and decrypt methods
noise/functions.py:
- Keypair constructors now guarded from invalid length of given
public/private bytes
- _25519_generate_keypair now returns proper class instance
requirements.txt:
- specified versions of packages that are compatible with currently used source code
Cryptography ships with OpenSSL 1.0.2g when it's installed against
python3.7. Old OpenSSL is largely incompatible with this package.
Testing (and any required development for ensuring compatibility) will
be turned on again when Cryptography wheel for python3.7 will ship with
new OpenSSL
