.. index:: single: cryptography

The modules described in this chapter implement various algorithms of a cryptographic nature. They are available at the discretion of the installation. Here's an overview:

.. toctree::

   hashlib.rst
   hmac.rst
   md5.rst
   sha.rst

.. index::
   pair: AES; algorithm
   single: cryptography
   single: Kuchling, Andrew

Hardcore cypherpunks will probably find the cryptographic modules written by A.M. Kuchling of further interest; the package contains modules for various encryption algorithms, most notably AES. These modules are not distributed with Python but available separately. See the URL http://www.amk.ca/python/code/crypto.html for more information.
