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