15. Cryptographic Services

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:

hmac Keyed-Hashing for Message Authentication (HMAC) implementation for Python.

md5 RSA's MD5 message digest algorithm.

sha NIST's secure hash algorithm, SHA.

Hardcore cypherpunks will probably find the cryptographic modules written by A.M. Kuchling of further interest; the package adds built-in modules for DES and IDEA encryption, provides a Python module for reading and decrypting PGP files, and then some. These modules are not distributed with Python but available separately. See the URL http://www.amk.ca/python/code/crypto.html for more information.
