made this out of boredom when a person was worried about storing their users' passwords as MD5 hashes in a database due to the recent collision in the algorithm. I thought he was being overparanoid so I wanted to see how fast the password I use could be brute forced. I tried a few similar programs but they didn't perform as fast as I thought they would, so I decided to implement a cracker of my own in C. To my satisfaction it was much faster than many I found, although I don't think this is anything close to the best, in fact I think brute forcing any type of hashed password is a waste of time. This program is able to hash and compare about 120,000 passwords per second on my P4 2.6 ghZ processor. Fixed threading to work on Win95/98. Some other benchmarks included in zip file.
