6 ** md5.h -- Header file for implementation of MD5 **
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 **
