***********************************************************************
** md5.h -- header file for implementation of MD5 **
** RSA Data Security, Inc. MD5 Message-Digest Algorithm **
** Created: 2/17/90 RLR **
** Revised: 12/27/90 SRD,AJ,BSK,JT Reference C version **
** Revised (for MD5): RLR 4/27/91 **
** -- G modified to have y&~z instead of y&z **
** -- FF, GG, HH modified to add in last register done **
** -- Access pattern: round 2 works mod 5, round 3 works mod 3 **
** -- distinct additive constant for each step **
** -- round 4 added, working mod 7 **
***********************************************************************

/*
* Edited 7 May 93 by CP to change the interface to match that
* of the MD5 routines in RSAREF. Due to this alteration, this
* code is "derived from the RSA Data Security, Inc. MD5 Message-
* Digest Algorithm". (See below.) Also added argument names
* to the prototypes.
