39 * With the following changes: uint64_t => uint32_t[2]
40 * Commented out #include <sys/cdefs.h>
41 * Commented out the __BEGIN and __END _DECLS, and the __attributes.
42 * Commented out MD4End, MD4File, MD4Data
43 * Commented out header file protection #ifndef,#define,#endif

49 * This code implements the MD4 message-digest algorithm.
50 * The algorithm is due to Ron Rivest. This code was
51 * written by Colin Plumb in 1993, no copyright is claimed.
52 * This code is in the public domain; do with it what you wish.
53 * Todd C. Miller modified the MD5 code to do MD4 based on RFC 1186.
55 * Equivalent code is available from RSA Data Security, Inc.
56 * This code has been tested against that, and is equivalent,
57 * except that you don't need to include two pages of legalese
