Thread: can hashcat crack md5($s.'-'.md5($p)) ?
Post: RE: can hashcat crack md5($s.'-'.md5($p)) ?

no, lite/plus do not have any mode that would work with that algorithm. but, cpu hashcat can crack them using mode 7 if you manually append a dash to each salt.

this is expected because you aren't giving the left side enough work to do. i'm surprised your gpu utilization is that high, when i try your mask i only get about 2% utilization on one GPU.

they have been tested, and it is recommended that you stay with 12.8. you haven't stated which OS you're using so i cannot give specifics.

Thread: oclHashcat-plus mask batchscript
Post: RE: oclHashcat-plus mask batchscript

plus has supported incremental mode for a while now. so if you use -i with ?l?l?l?l?l?l?l?l it will find a 7-char passwd that matches that mask as well.

Post: RE: What am I missing?

looks like you're using the wrong driver. need to use catalyst 12.8. if you're going to use catalyst 12.10, then you need to stop x11 and run hashcat as root.

the mask you are looking for is -1 ABCDEF?d ?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1?1 however, plus does not support 16-char passwords.

Post: RE: oclHashcat-* cannot utilise 2nd HD7970

1. You need to uninstall the AMD APP SDK. 2. Catalyst 12.10 does not support multi-GPU when x11 is running.. Either use 12.8, or ensure you do not have x11 running while cracking.
