16Crack Software
16Crack was the only software I used. I wrote it myself. It's hobby software not currently available
for download. It ran on one AMD CPU that has six cores, for roughly 30 hours of cracking. It is a
CPU-based, fully multithreaded password hash cracker that focuses on common consonant vowel patterns
(CVCCVC, etc).
Performance
16Crack cracked 50,431 passwords (KoreLogic counts this as 51,768... not sure why). [We think there
were duplicates in some of the challenges, giving 16Crack some extra credit.] I'm pleased by
16Crack's performance. Only four teams cracked more hashes than I did so 16Crack placed 5th in terms
of sheer number of cracks (although I was not ranked that high because of the weighted scoring
system). Not bad for a one man team with one CPU using homemade software.
