     MD5, MD5Init, MD5Transform — message digest routines


     #include <sys/types.h>
     #include <sys/md5.h>

     MD5Init(MD5_CTX *buf);

     MD5Transform(uint32_t buf[4], const unsigned char block[64]);


     The MD5 module implements the RSA Data Security, Inc. MD5 Message-Digest Algorithm (MD5).
     It produces 128-bit MD5 Digest of data.

     MD5Init          must be called just before MD5Transform() will be used to produce a digest.
                      The buf argument is the storage for the digest being produced on subsequent
                      calls to the MD5Transform() routine.

     MD5Transform     is the core of the MD5 algorithm, this alters an existing MD5 hash kept in
                      buf to reflect the addition of 64 characters of new data passed in block


     The code for MD5 transform was taken from Colin Plumb's implementation, which has been
     placed in the public domain.  The MD5 cryptographic checksum was devised by Ronald Rivest,
     and is documented in RFC 1321, "The MD5 Message Digest Algorithm".
