Native MD5 implementation in Common Lisp

This package implements the MD5 Message-Digest Algorithm, as defined in RFC 1321, in Common Lisp. Warning: The MD5 Message-Digest Algorithm has been compromised as a cryptographically secure hash for a long time, with known theoretical and practical attacks. Therefore, use of this implementation is recommended only for legacy purposes or cases where a cryptographically secure hash is not required. For all other uses, consider one of the newer SHA-2 or SHA-3 secure hash standards, or whatever is currently deemed cryptographically secure.
