7  ** RSA Data Security, Inc. MD5 Message Digest Algorithm **
8  ** 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 **
