5 ** md5.h -- header file for implementation of MD5 **
6 ** RSA Data Security, Inc. MD5 Message-Digest Algorithm **
7 ** Created: 2/17/90 RLR **
8 ** Revised: 12/27/90 SRD,AJ,BSK,JT Reference C version **
9 ** Revised (for MD5): RLR 4/27/91 **
10 ** -- G modified to have y&~z instead of y&z **
11 ** -- FF, GG, HH modified to add in last register done **
12 ** -- Access pattern: round 2 works mod 5, round 3 works mod 3 **
13 ** -- distinct additive constant for each step **
14 ** -- round 4 added, working mod 7 **
