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