The cryptography library is designed to be a "one-stop-shop" for all your cryptographic needs in Python.

As an alternative to the libraries that came before it, cryptography tries to address some of the issues with those libraries: - Lack of PyPy and Python 3 support. - Lack of maintenance. - Use of poor implementations of algorithms (i.e. ones with known side-channel attacks). - Lack of high level, "Cryptography for humans", APIs. - Absence of algorithms such as AES-GCM. - Poor introspectability, and thus poor testability. - Extremely error prone APIs, and bad defaults.

This package contains the Python 3 version of cryptography.
