Download MD Crack from: http://mdcrack.openwall.net
and run this in a command prompt
MDCrack-sse.exe --algorithm=FREEBSD --charset=abcdefghijklmnopqrstuvwxyz $1$aOt7cely$BlSDARE/DgHRtJ4PJaEti/
*** Note ***
If you have a P4 with hyper threading run 2 benchmarks
MDCrack-sse.exe --benchmark=2 --threads=1
and look for the speeds for 'FreeBSD MD5'
I get 4,500 hashes/sec with one thread and 2,100 hashes/sec with the default two threads on a 2.8 GHz P4.
FreeBSD MD5 is ridiculously slow, it's purpose is to deter people from cracking passwords.
MD Crack is actually one of the fastest MD5 crackers. There's only one that I know of that can beat it... Mine, by about 40%. Although my code is in the state of proof of concept and not a cracker, it still is 40% faster at 12.8 million 'MD5 crack hashes'/sec or 9.8 million 'MD5 full hashes'/sec.
The best way to crack it is JTR - pointp
Ohh wow I'm slow I just realized that's John The Ripper.
