# 14. 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:

- 14.1. `hashlib` — Secure hashes and message digests
- 14.2. `hmac` — Keyed-Hashing for Message Authentication

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.pycrypto.org for more information.
