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