| 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: |
| |
| \begin{description} |
| |
| \item[md5] |
| --- RSA's MD5 message digest algorithm. |
| |
| \item[mpz] |
| --- Interface to the GNU MP library for arbitrary precision arithmetic. |
| |
| \item[rotor] |
| --- Enigma-like encryption and decryption. |
| |
| \end{description} |
| |
| Hardcore cypherpunks will probably find the Python Cryptography Kit of |
| further interest; the package adds built-in modules for DES and IDEA |
| encryption, and provides a Python module for reading and decrypting |
| PGP files. The Python Cryptography Kit is not distributed with Python |
| but available separately. See the URL |
| \file{http://www.cs.mcgill.ca/\%7Efnord/crypt.html} for more information. |
