** Created: 2/17/90 RLR **
9
** Revised: 12/27/90 SRD,AJ,BSK,JT Reference C version **
10
** Revised (for MD5): RLR 4/27/91 **
11
** -- G modified to have y&~z instead of y&z **
12
** -- FF, GG, HH modified to add in last register done **
13
** -- Access pattern: round 2 works mod 5, round 3 works mod 3 **
14
** -- distinct additive constant for each step **
15
** -- round 4 added, working mod 7 **

***********************************************************************
20
* Edited 7 May 93 by CP to change the interface to match that
21
* of the MD5 routines in RSAREF. Due to this alteration, this
22
* code is "derived from the RSA Data Security, Inc. MD5 Message-
23
* Digest Algorithm". (See below.) Also added argument names
