python-twofish
==============
Bindings for the Twofish implementation by Niels Ferguson libtwofish-dev_.
Compatible with Python 2.6, 2.7 and 3.3.
The library performs a self-test at each import.
.. _libtwofish-dev: http://packages.debian.org/sid/libtwofish-dev
Installation
------------
::
pip install twofish
Usage
-----
Create a ``twofish.Twofish`` instance with a key of length ]0, 32] and then use the ``encrypt`` and ``decrypt`` methods on 16 bytes blocks.
All values must be binary strings (``str`` on Python 2, ``bytes`` on Python 3)
**[WARNING]** this should be used in a senseful cipher mode, like CTR or CBC. If you don't know what this mean, you should probably usa a higher level library.
Example
-------
>>> from twofish import Twofish
>>> T = Twofish(b'*secret*')
>>> x = T.encrypt(b'YELLOWSUBMARINES')
>>> print(T.decrypt(x).decode())
YELLOWSUBMARINES
