    Thread: Pipe is -very- slow
Post: RE: Pipe is -very- slow

You're running a straight dictionary attack against a fast hash, so it is impossible to gain GPU acceleration as you do not have an amplifier. You then made an already-slow attack even slower by using...

Post: RE: Please grant me one dumb question

Hashing is not encryption, and hashcat's focus is on cracking hashes, not breaking encryption. There is some small overlap between the two with programs which create encrypted files by passing the...

Post: RE: Pipe is -very- slow

It's a potential workaround, not a magic fix. Pipe incurs more host-device transfers and is more sensitive to PCI-e bus speed & latency. You should be using cpu hashcat for this attack.

Post: RE: Pipe is -very- slow

It depends on the hardware and the workload. There's no "one size fits all" answer, you just have to know your tools. In this case, it looks like Mem5 has a really underpowered CPU if he's only pullin...

Correct, it is not a reference card, it is an OEM design based on the old GTX 670 reference design. Furthermore, the old "if it has 'GAMING' in the title it's not reference design" line really applies...

No. TEA is a block cipher, and hashcat targets hash algorithms. See also https://hashcat.net/forum/thread-4874-post-27356.html#pid27356

Post: RE: FirePro V7800

Firepro v7800 is an underclocked HD 5850. So old and slow. Moreover, AMD is dropping support for their VLIW5 cards in the next driver release, so you wouldn't be able to use this GPU for very long.

No, Hashcat doesn't support cracking DES encryption. But it does support some password hashing algorithms which incorporate DES (descrypt, LM hash, etc.) Hashcat does support some popular encrypted fi...

Just basic, elementary maths. Keyspace for this attack is 16^64. Fastest GPU (Titan X) can crack sha256 at 2.2 GH/s. This means you would need 1.6x10^54 Titan X GPUs to crack this password in one mill...
