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:

md5 RSA's MD5 message digest algorithm.

sha NIST's secure hash algorithm, SHA.

mpz Interface to the GNU MP library for arbitrary precision arithmetic.

rotor Enigma-like encryption and decryption.

Hardcore cypherpunks will probably find the cryptographic modules written by Andrew 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.
