35  ** Revised: 12/27/90 SRD,AJ,BSK,JT Reference C version **
36  ** Revised (for MD5): RLR 4/27/91 **
37  ** -- G modified to have y&~z instead of y&z **
38  ** -- FF, GG, HH modified to add in last register done **
39  ** -- Access pattern: round 2 works mod 5, round 3 works mod 3 **
40  ** -- distinct additive constant for each step **
41  ** -- round 4 added, working mod 7 **

48  ** To form the message digest for a message M **
49  ** (1) Initialize a context buffer mdContext using MD5Init **
50  ** (2) Call MD5Update on mdContext and M **
51  ** (3) Call MD5Final on mdContext **
52  ** The message digest is now in mdContext->digest[0...15] **
