Provides a basic and primitive hmac. From wikipedia: "In cryptography, HMAC (Hash-based Message Authentication Code) is a specific construction for calculating a message authentication code (MAC) involving a cryptographic hash function in combination with a secret key."
I would welcome improvements. This implementation is not very performant and could use better integration with the message digest system.

List of Procedures
hmac[procedure] (hmac key digest-primitive #!optional (block-size 64))
Takes key and digest-primitive and returns a function that takes message and produces an hmac.
(use hmac sha1) ((hmac "secret-key" (sha1-primitive)) "message")
Removed dependency on srfi-4-utils as it is GPL and hmac is BSD.
Fixed egg category (was cryptography, now crypt)
Forgot to update .setup to match version in .release-info
Fixed install dependency bug
