+ *
+ * Reference:
+ *
+ *   This code implements the MD5 message-digest algorithm.
+ *   The algorithm is due to Ron Rivest.  This code was
+ *   written by Colin Plumb in 1993, no copyright is claimed.
+ *
+ *   This code is in the public domain; do with it what you wish.
+ *
+ *   Equivalent code is available from RSA Data Security, Inc.
+ *   This code has been tested against that, and is equivalent,
+ *   except that you don't need to include two pages of legalese
+ *   with every copy.
+ *
+ *   To compute the message digest of a chunk of bytes, declare an
+ *   md5_context_s structure, pass it to md5_init, call md5_update as
+ *   needed on buffers full of bytes, and then call md5_final, which
+ *   will fill a supplied 16-byte array with the digest.
+ *
+ *   See README and COPYING for more details.
