CryptoLyzer 0.1.0

Fast and flexible cryptographic protocol analyzer

What is it and what is it not?

As the project name CryptoLyzer implies, it is an cryptographic protocol analyzer. The main purpose of creating this application is the fact, that cryptography protocol analysis differs in many aspect from establishing a connection using a cryptographic protocol. Analysis is mostly testing where we trigger special and corner cases of the protocol and we also trying to establish connection with hardly supported, experimental, obsoleted or even deprecated mechanisms or algorithms which are may or may not supported by the latest or any version of an implementation of the cryptographic protocol.

As follows, it is neither a comprehensive nor a secure client/server implementation of any cryptographic protocol. On the one hand analyzer implements only the absolutely necessary parts of the protocol to interact with servers. On the other it may use completely insecure algorithms and mechanisms. It is not designed and contraindicated to use these client/server implementations establishing secure connections. If you are searching for proper cryptographic protocol implementations, there are several existing wrappers and native implementations for Python (eg: M2Crypto, pyOpenSSL, Paramiko, …).

Quick start

CryptoLyzer can be installed directly via pip:

pip install cryptolyzer

Development environment

If you want to setup a development environment, you are in need of pipenv.

$ cd cryptolyzer
$ pipenv install --dev
$ pipenv shell
