    Thread: Getting salt from known hash and pass
Post: RE: Getting salt from known hash and pass

Yep - not to self-promote too much, but I answered it here: https://security.stackexchange.com/a/171922/6203 The key concept is that the salt is actually part of the password, so you're trying to cr...

    Thread: Wordlist form Weakpass - File Format
Post: RE: Wordlist form Weakpass - File Format

Your instincts are good. Yes, they should be rare - even historically, and pretty much non-existent for web-based passwords. Many "wordlists" are just massive mashups of other people's ideas of what m...

Agreed - I think the OP was motivated by convenience, not efficiency. :D

Strip the unneeded field before handing the hashlist to hashcat.

And its Rust cousin, PACK2 (fewer features at this writing, but has some cool ones that PACK does not, and is also faster for some of the ones they have in common): https://github.com/hops/pack2

    Thread: BigCrypt hash
Post: RE: BigCrypt hash

I don't think that hashcat supports it. John the Ripper supports BigCrypt, which is actually an HP-authored extension of descrypt that supports longer passwords. I think it is still found on HP-UX but...

That would be --elem-cnt-min=4 --elem-cnt-max=7, then. :D

Post: RE: Specific pattern syntax help

I don't have a hashcat-only solution for you, but something like this might work - basically, append that separate to all your words, and then use a rule that *removes* the final separator from the st...

Fair point - I was reading too fast! Honestly not something that's come up before (for me, anyway).

This violates our forum rules. https://hashcat.net/forum/archive/index.php?announcement-2.html > "Do not ask people to crack your hash. It does not matter if you are willing to pay."

Post: RE: Truncated MD5 to plaintext possibilities

There's no stock support for this in hashcat - it would be doable, but would require a custom kernel.

Those do seem odd, and don't sound like the Nitro hashes that I'm aware of, which are straight bcrypt as mentioned in the Have I Been Pwned list. It almost sounds like someone replaced truncated an...

Rurasort is the one I'm aware of as well. It's a tricky problem, because different combinations of rules and/or base words can produce the same results, so deriving the originals can be non-trivial...

This is a pretty complex setup - that is likely to be difficult to troubleshoot, and the segfault is very likely to be due to an issue outside of hashcat entirely (such as within K a l i). You are ...

hashcat has no built-in multi-chassis support (other than --skip/--limit and/or loose collaboration with 'brain' mode). If you want automated distribution of a single attack across multiple chassis...
