NAME
MD5 MD5Init MD5Transform - message digest routinesSYNOPSIS
In sys/types.h In sys/md5.h Ft void Fn MD5Init MD5_CTX *buf Ft void Fn 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 Fn 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 Fn 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".Contenus ©2006-2024 Benjamin Poulain
