+ * This file is part of the NuttX RTOS:

+ *   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.

+ *

+ *   See README and COPYING for more details.

+ *
