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. See the URL http://starship.python.net/crew/amk/python/code/crypto.html or send email to email@example.com for more information.
