- /*
- * 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
- * MD5Context 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 <ijackson@nyx.cs.du.edu>.
- * Still in the public domain.
- *
- * Josh Coalson: made some changes to integrate with libFLAC.
- * Still in the public domain.
