7  * This code implements the MD5 message-digest algorithm.
8  * The algorithm is due to Ron Rivest. This code was
9  * written by Colin Plumb in 1993, no copyright is claimed.
10  * This code is in the public domain; do with it what you wish.
11  *
12  * Equivalent code is available from RSA Data Security, Inc.
13  * This code has been tested against that, and is equivalent,
14  * except that you don't need to include two pages of legalese
15  * with every copy.
16  *
17  * To compute the message digest of a chunk of bytes, declare an
18  * MD5Context structure, pass it to MD5Init, call MD5Update as
19  * needed on buffers full of bytes, and then call MD5Final, which
20  * will fill a supplied 16-byte array with the digest.
