- *   Author: Darcy Gong

- *

- * 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

- *   MD5Context structure, pass it to MD5Init, call MD5Update as

- *   needed on buffers full of bytes, and then call MD5Final, which

- *   will fill a supplied 16-byte array with the digest.
