MD5(9) OpenBSD Kernel Manual MD5(9)NAME
md5 - message digest routines
SYNOPSIS
#include <sys/kernel.h>
void
MD5Init(u_int32_t buf[4]);
void
MD5Transform(u_int32_t buf[4], u_int32_t const in[16]);
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 16
longwords of new data passed in in 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".
