NAME

       MD5, MD5Init, MD5Transform — message digest routines

SYNOPSIS

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

       void
       MD5Init(MD5_CTX *buf);

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

DESCRIPTION

       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 argument.

COPYRIGHTS

       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".
