25 * This is the header file for the MD5 message-digest algorithm.
26 * The algorithm is due to Ron Rivest. This code was
27 * written by Colin Plumb in 1993, no copyright is claimed.
28 * This code is in the public domain; do with it what you wish.
29 *
30 * Equivalent code is available from RSA Data Security, Inc.
31 * This code has been tested against that, and is equivalent,
32 * except that you don't need to include two pages of legalese
33 * with every copy.
34 *
35 * To compute the message digest of a chunk of bytes, declare an
36 * MD5Context structure, pass it to MD5Init, call MD5Update as
37 * needed on buffers full of bytes, and then call MD5Final, which
38 * will fill a supplied 16-byte array with the digest.
39 *
40 * Changed so as no longer to depend on Colin Plumb's `usual.h'
41 * header definitions; now uses stuff from dpkg's config.h
42 * - Ian Jackson <ian@chiark.greenend.org.uk>.
43 * Still in the public domain.
44 *
45 * Changed MD5Update to take a void * for easier use and some other
46 * minor cleanup. - Henrik Nordstrom <henrik@henriknordstrom.net>.
47 * Still in the public domain.
48 *
49 * Prefixed all symbols with "Squid" so they don't collide with
50 * other libraries. Duane Wessels <wessels@squid-cache.org>.
51 * Still in the public domain.
