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) - -;;; Copyright and licence: ---------------------------------------------------- - -;; Copyright (C) 1995 by Gareth Rees -;; Derived from the RSA Data Security, Inc.
