      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                                 **
