21 * This is the header file for the MD5 message-digest algorithm.
22 * The algorithm is due to Ron Rivest. This code was
23 * written by Colin Plumb in 1993, no copyright is claimed.
24 * This code is in the public domain; do with it what you wish.
26 * Equivalent code is available from RSA Data Security, Inc.
27 * This code has been tested against that, and is equivalent,
28 * except that you don't need to include two pages of legalese
31 * To compute the message digest of a chunk of bytes, declare an
32 * MD5Context structure, pass it to MD5Init, call MD5Update as
33 * needed on buffers full of bytes, and then call MD5Final, which
34 * will fill a supplied 16-byte array with the digest.
36 * Changed so as no longer to depend on Colin Plumb's `usual.h'
37 * header definitions; now uses stuff from dpkg's config.h
38 * - Ian Jackson <ijackson@nyx.cs.du.edu>.
39 * Still in the public domain.
