    Thread: How do I crack substr hash?
Post: RE: How do I crack substr hash?

hashcat does not support anything like that. however, there are only 2**32 possible combinations, so there's a 50% chance you'll find a collision after 77k attempts, and a 75% chance after 110k attem...

You're welcome. The advantage of using an OS that has an SDLC and thus has long-term stable releases is that the software versions do not change. Even if you update the OS, the versions will all stay...

hashcat only recognizes cards that the opencl platform tells it about. the opencl platform gets its information from the driver. the driver depends on x11. so you will need to generate a new xorg.conf...

no, i mean write your own program or script that will generate a collision. it doesn't have to be very fast or efficient because you are likely to find a collision in only 110,000 guesses when compari...

RDP uses a virtual display driver rather than fglrx, and that is likely why ADL is failing. It's not a problem per se, you just won't see temps or get fan control. The biggest question is why are you...

Post: RE: It never stops running

phpass is a slow algorithm, and you're using an nvidia gpu. so yes, it will probably take a long time to brute force. better to do wordlist and rule based attacks.

If you have an AMD GPU, you should not be using cudaHashcat64.exe. CUDA is for Nvidia only. Maybe you can post your command line.
