    Thread: GNUPG Symmetric help
Post: RE: GNUPG Symmetric help

hashcat currently has no direct support for PGP/GPG. But John the Ripper does have the 'gpg-opencl' format, which is significantly faster on GPU that the basic 'gpg' format, so using a GPU should s...

* You should definitely use hashcat 4.0.1 * Please don't use the word 'dehash'; that's not what any hash-cracking utility does (because it implies reversing a hash, which is by definition impossible ...

You're welcome! OK, I added a little more content to that wiki page, which should hopefully help the next person, anyway. :) Thanks for the nudge!

princeprocessor can generate all possible combinations so quickly, and hashcat can (usually) use them so quickly, there's no real value in trying to narrow down the range of possibilities. Code: -- ...

Welcome! Unless it is an extremely slow hash, or the wordlists are much larger than the example that you're giving, I would just use princeprocessor (https://github.com/hashcat/princeprocessor) to...

    Thread: do hashcat-utils use the gpu's?
Post: RE: do hashcat-utils use the gpu's?

If you are piping combinator3 output to hashcat, then if hashcat reports that it is using the GPUs, then it is. What's more likely is that the rate of wordlist generation is low enough that you'd n...

There's no way to do this with hashcat - it's not a rules-level problem, but an algorithm-level problem. Outside of hashcat, this algorithm isn't natively supported by MDXfind and probably not by H...

Neither. :) Go NVIDIA, 10xx series (1070, 1080, 1080Ti). If you get Founder's Edition (recommended), the vendor doesn't matter, because they all follow the same NVIDIA spec.

The salt is intrinsic to the hash. The only way to rework the salts would be if you already had the plain text password.
