Crunch is unnecessary for most attacks: * Limiting duplicate characters is not worth the sacrifice in speed * Resumption of candidate generation is built in natively to hashcat Generating candi...

If your target password is likely less than the max supported by an optimized kernel, adding "-O" to your command line will be significantly faster. This max value varies from hashtype to hashtype - c...

Some of the characters are interpreted by your command shell - you might have to backslash one or more of the characters that have special meaning in the shell, such as !, $, ', ", etc. But in your c...

Hi, oscam. Last I'd heard (2012), key-based DES is not supported. The hash type 1500 - "descrypt, DES(Unix), Traditional DES" - is not keyed DES encryption. It's a format used to hash passwords o...

Those cards are two slots wide, but it looks like the card slots are spaced such that you can get all three in there? epixoip says that the one-fan cards are superior, so that's good. If you're prim...

It's certainly a solid all-around platform, but it may be more than you need depending on your goals. Are you just looking to do GPU hashcat (oclhashcat), or other things as well? oclhashcat jobs...

The numbers that I posted, plus the Google doc, should let you compare R9 290X with 970 SC. I prefer NVIDIA over AMD, even with a slightly lower speed, but YMMV. :)

If it's WinZip-compatible ZIP, then it would be covered by mode 13600. You'll have to extract the hash using zip2john (from John the Ripper). This thread may be useful: https://hashcat.net/forum/th...

It depends. This boils down to the time/memory tradeoff. I'll lay out some of the concepts. Most real-world passwords are of sufficiently low quality that if they are stored poorly (unsalted/fast h...

OK, that makes sense. So as soon as you have more than two or three hashes, hashcat will be faster even for limited bruteforce criteria that I listed.
