AbstractFPGA implementation of MD5 hash algorithm is faster than its software counterpart, but a pre-image brute-force attack on MD5 hash still needs 2ˆ(128) iterations theoretically. This work attempts to improve the speed of the brute-force attack on the MD5 algorithm using hardware implementation. A full 64-stage pipelining is done for MD5 hash generation and three architectures are presented for guess password generation. A 32/34/26-instance parallelization of MD5 hash generator and password generator pair is done to search for a password that was hashed using the MD5 algorithm. Total performance of about 6G trials/second has been achieved using a single Virtex-7 FPGA device.
