	RFC 1320:

        Title:      The MD4 Message-Digest Algorithm
       	Author:     R. Rivest
	Mailbox:    rivest@theory.lcs.mit.edu
	Pages:      20
	Characters: 32,407
	Obsoletes:  RFC 1186

This document describes the MD4 message-digest algorithm. The
algorithm takes as input a message of arbitrary length and produces as
output a 128-bit "fingerprint" or "message digest" of the input.  It
is conjectured that it is computationally infeasible to produce two
messages having the same message digest, or to produce any message
having a given prespecified target message digest. The MD4 algorithm
is intended for digital signature applications, where a large file
must be "compressed" in a secure manner before being encrypted with a
private (secret) key under a public-key cryptosystem such as RSA.
