| 4 | ** RSA Data Security, Inc. MD5 Message-Digest Algorithm ** |
| 5 | ** Created: 2/17/90 RLR ** |
| 6 | ** Revised: 12/27/90 SRD,AJ,BSK,JT Reference C version ** |
| 7 | ** Revised (for MD5): RLR 4/27/91 ** |
| 8 | ** -- G modified to have y&~z instead of y&z ** |
| 9 | ** -- FF, GG, HH modified to add in last register done ** |
| 10 | ** -- Access pattern: round 2 works mod 5, round 3 works mod 3 ** |
| 11 | ** -- distinct additive constant for each step ** |
| 12 | ** -- round 4 added, working mod 7 ** |
