Post: RE: Bruteforce + rules

You might try increasing the number of masks, to see if that improves performance. But generally speaking, I suspect that full bruteforce has some attack-specific optimizations that make it pretty ...

Post: RE: Bruteforce + rules

OK, this is ugly as heck, and buggy (it doesn't fully emulate bruteforce for the last two characters), but it's getting close: Code: -- $ for item in `mp64 '?aTEMP?a'`; do echo "di6${item}iE${it...

Man, I thought I tried that and it didn't work. But I checked and it was failing for other syntax reasons. So: Code: -- $ cat double.rule d $ mp64 '$?a$?a' >append-aa.rule $ head appen...

If you delete the empty potfile, is it recreated on the next run?

Post: RE: 6.1.1 potfile

@philsmd, I can recreate this - for both TrueCrypt and Veracrypt, it seems, if a session is specified, but a potfile is not, then ses.potfile is not created on the fly that I can find (on Linux, anywa...

Huh - when I did my veracrypt testing in late 2018, it used the filename. This seems like the approach that would cause the least amount of confusion. Otherwise, we'll have a steady stream of users as...

*lightbulb* Ahhhh ... so they only need to be "proportional" within specific attack type/combos, and that's why they can't be compared across them! Because it's *called* a keyspace ... but it isn't...

Yeah, the naming cat is probably already out of the bag. I've clarified the FAQ section to make it very clear that hashcat --keyspace is specifically for distributing work, and does not directly co...

I'd recommend something other than K a l i for the main OS. It doesn't play well with OpenCL and hashcat sometimes.

Post: RE: Using newline character as part of mask attack

Regardless of attack, -m 0 is unsalted and -m 20 is salted. If this concept isn't familiar, search a bit for "password" and "salting".
