/*

 * This is the header file for 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

 * MD5_CTX 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.

 *

 * Changed so as no longer to depend on Colin Plumb's `usual.h'

 * header definitions; now uses stuff from dpkg's config.h

 *  - Ian Jackson <ian@chiark.greenend.org.uk>.

 * Still in the public domain.
