40 * With the following changes: uint64_t => uint32_t[2]
41 * Commented out #include <sys/cdefs.h>
42 * Commented out the __BEGIN and __END _DECLS, and the __attributes.
46 * This code implements the MD5 message-digest algorithm.
47 * The algorithm is due to Ron Rivest. This code was
48 * written by Colin Plumb in 1993, no copyright is claimed.
49 * This code is in the public domain; do with it what you wish.
51 * Equivalent code is available from RSA Data Security, Inc.
52 * This code has been tested against that, and is equivalent,
53 * except that you don't need to include two pages of legalese
