    Thread: [PrinceProcessor] Trying to change --pw-max
Post: RE: [PrinceProcessor] Trying to change --pw-max

Yeah, the startup time is non-trivial for sure. A big value of PRINCE is in keeping "state" about which words appear most frequently (based on their order in the original wordlist). So if that's not i...

    Thread: Brain as a centralized potfile?
Post: RE: Brain as a centralized potfile?

1. Yes. All candidates are centrally reported and indexed. For slow hashes, this is effective, because it allows all clients to skip those candidates. For fast hashes, this will quickly bottleneck the...

Hashcat won't do this today. You might be able to simulate it with John the Ripper's "single" mode, by creating an artificial shadow file, with the expected password in the username field.

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...

hashcat doesn't need an external wordlist for this. Just use -a 3 and ?d?d?d?d?d?d.

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...
