In this 2011 thread: https://hashcat.net/forum/thread-698.html ... someone asked about "wordlist clipping" - being able to truncate passwords instead of rejecting them. The suggestion at the t...

To clarify this is a hashcat manual of sorts, in Spanish. Cool, thanks!

    Thread: [sha256] Hash inside a hash
Post: RE: [sha256] Hash inside a hash

If it's the case that it's sha256(sha256(pass)), trying to discover that original 'pass' string is much more efficient. hashcat doesn't support that specific combo, but other tools (John the Ripper...

Post: RE: [sha256] Hash inside a hash

If the first sha256 was based on a shorter, less random string, you're far better off attacking that, and then just running sha256 on it. :) But if the first sha256 is of something large or random,...

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...

Sounds like the hash isn't in the expected format. If you try the exact same attack on the example 9700 hash here: https://hashcat.net/wiki/doku.php?id=example_hashes ... does your attack work? ...

Yep, that happens automatically - state is saved periodically to a restore file, and you use --restore to restore.

Also note that upcoming 1.38 release of hashcat has *significantly* better descrypt and LM performance, if those are of interest to you.

Hybrid (-a 6 - word list on left-hand side, mask on right) should work for your use case. Please try again, and post your command line for a cross-check.

There has been some work in this space, but it's a challenging problem. And it's highly idiosyncratic in that the usefulness of any given wordlist and ruleset depends heavily on the nature of the pass...

Post: RE: Wordlist massive attack

You can assemble the passphrases from a one-word-per-line wordlist, using princeprocessor, and then pipe it to hashcat, using one of the prince_*.rule rules files to supply more work to the GPUs.

The traditional answer: This is a known issue. Because rules are applied on GPU, this can't be fixed for fast hashes without significantly slowing down cracking - and doesn't need to be fixed for s...
