-// MD5 stands for Message Digest algorithm 5.
-// MD5 is a robust hash function, designed for cyptography, but often used
-// for file checksums.  The code is complex and slow, but has few
-// collisions.
-// See Also:
-//   http://en.wikipedia.org/wiki/MD5
-
-// These functions perform MD5 operations. The simplest call is MD5Sum() to
-// generate the MD5 sum of the given data.
-//
-// You can also compute the MD5 sum of data incrementally by making multiple
-// calls to MD5Update():
-//   MD5Context ctx; // intermediate MD5 data: do not use
-//   MD5Init(&ctx);
-//   MD5Update(&ctx, data1, length1);
-//   MD5Update(&ctx, data2, length2);
-//   ...
-//
-//   MD5Digest digest; // the result of the computation
-//   MD5Final(&digest, &ctx);
-//
-// You can call MD5DigestToBase16() to generate a string of the digest.
-
-// The output of an MD5 operation.
