-;;; md5.el -- MD5 Message Digest Algorithm
-;;; Gareth Rees <gdr11@cl.cam.ac.uk>
-
-;; LCD Archive Entry:
-;; md5|Gareth Rees|gdr11@cl.cam.ac.uk|
-;; MD5 cryptographic message digest algorithm|
-;; 13-Nov-95|1.0|~/misc/md5.el.Z|
-
-;;; Details: ------------------------------------------------------------------
-
-;; This is a direct translation into Emacs LISP of the reference C
-;; implementation of the MD5 Message-Digest Algorithm written by RSA
-;; Data Security, Inc.
-;;
-;; The algorithm takes a message (that is, a string of bytes) and
-;; computes a 16-byte checksum or "digest" for the message. This digest
-;; is supposed to be cryptographically strong in the sense that if you
-;; are given a 16-byte digest D, then there is no easier way to
-;; construct a message whose digest is D than to exhaustively search the
-;; space of messages. However, the robustness of the algorithm has not
-;; been proven, and a similar algorithm (MD4) was shown to be unsound,
-;; so treat with caution!
-;;
-;; The C algorithm uses 32-bit integers; because GNU Emacs
-;; implementations provide 28-bit integers (with 24-bit integers on
-;; versions prior to 19.29), the code represents a 32-bit integer as the
-;; cons of two 16-bit integers. The most significant word is stored in
-;; the car and the least significant in the cdr. The algorithm requires
-;; at least 17 bits of integer representation in order to represent the
-;; carry from a 16-bit addition.
-
-;;; Usage: --------------------------------------------------------------------
-
-;; To compute the MD5 Message Digest for a message M (represented as a
-;; string or as a vector of bytes), call
-;;
-;; (md5-encode M)
-;;
-;; which returns the message digest as a vector of 16 bytes. If you
-;; need to supply the message in pieces M1, M2, ... Mn, then call
-;;
-;; (md5-init)
-;; (md5-update M1)
-;; (md5-update M2)
-;; ...
-;; (md5-update Mn)
-;; (md5-final)
