Is there a version of those tools for ATI/AMD cards? It's just nice to test it out on locked ZIps,Rars I forgot passwords to from years ago to rescue my work files.
Just don't forget that cracking a .rar file takes a long time with a reasonable password. As I have found out.
Remember.. Services that display "how many thousands/millions of years would it take to crack your password" are based on the compute performance of a typical single desktop cpu.
It doesn't take in account an attacker with access to 1 TFLOPS or more GPU power 24/7. This sort of cluster can brute force 1000 billion combinations per second, about 2160 hours (3 months) to recover a 96-char password with alternating lower and uppercase characters, special symbols and numbers.
1 TFLOPS can be achieved with a farm of 196 radeon 6990's worth of hashing power. There are a few people with clusters this powerful mining all the time (maybe 2-3, Vladimir could have much more if he stopped renting his massive farms in the future)
