The MD5 encryption IP core is a fully compliant hardware implementation of the Message Digest Algorithm MD5, suitable for a variety of applications. It computes a 120-bit message digest for messages of up to (264 – 1) bits.
The MD5 algorithm is an improved version of the MD4, created by Professor Ronald L. Rivest of MIT, and is closely modeled after that algorithm. It operates on message blocks of 512 bits for which a 128-bit (4 x 32-bit words) digest is produced. Corresponding 32-bit words of the digest from consecutive message blocks are added to each other to form the message of the whole message.
The MD5 core is a fully synchronous design and has been evaluated in a variety of technologies. It is available optimized for ASICs or FPGAs.
