Python Hybrid Crypto

Python module which exposes a simple hybrid cryptography abstraction on top of KeyCzar and pycrypto.

Note

This module has NOT been extensively tested or audited so general usage is strongly discouraged at this point.

How it works

Key encapsulation scheme

Key encapsulation scheme uses RSA-OAEP public-key cryptography with 2048 bit key.

This functionality heavily relies on public-key cryptography functionality exposed by KeyCzar.

Data encapsulation scheme

Data encapsulation scheme uses AES in CBC mode with 256 bit key.

This release on primitives and functionality provided by pycrypto.

Example Usage

TBW.

Questions and Answers

Why do I need this, can't I just use keyczar directly?

KeyCzar exposes a higher level, safe and easy to use interface for handling both, asymmetric and symmetric encryption, but it doesn't provide a higher level interface for handling hybrid cryptography (well, that's not 100% accurate, because there is some support, but it's experimental and only available in Java).
