    NAME

    
    
    MD5
    
     
    MD5Init
    
     
    MD5Transform
    
     - message digest routines
    
     
    

    SYNOPSIS

       #include <sys/types.h>
       #include <sys/md5.h>
    void MD5Init (MD5_CTX *buf);
    void MD5Transform (u_int32_t buf[4] const unsigned char block[64]);
     

    DESCRIPTION

    The 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 Fa 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 Fa buf to reflect the addition of 64 characters of new data passed in Fa 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".
