3 | ** md5.h -- header file for implementation of MD5 ** | |
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 ** | |
