MDCrack is a free, feature filled password cracker designed to bruteforce several commonly used hash algorithms at a very aggressive speed rate. It can retrieve any password made of up to 8 characters (16 for PIX algorithms) and 55 characters when salted. In order to achieve the highest possible speed rate, this program uses several cores for each algorithm it supports. Each one of these cores provides a different level of optimization designed to best fit with a specific set of command line options. Whatever command line configuration is used, MDCrack will always arrange to use the best available core. To date, this program supports bruteforce attacks on MD2, MD4, MD5, NTLMv1 and PIX (enable and users) hashes, the list of algorithms is growing up. Multithreading allows for parallel cracking and load sharing between several CPUs and multiplies overall speed by the number of available processor(s).
