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

There may be other ways, but quitting and restoring the hashcat session will reread the pot file.

Thanks for the benchmark! Would be handy to have a 1050 Ti benchmark on the latest version (4.0.1) also, if you have time.

YW. Make sure that PW_MAX is 4x the length of your longest word. Enjoy!

Post: RE: PrinceProcessor

Assuming a dictionary whose longest word length is (for example) 12, and a four-word passphrase, then the maximum length of the entire passphrase is 12 x 4 = 48.

If we assume that the four words are Diceware-style, and truly chosen at random from a list, then for a four-word passphrase, princeprocessor would properly try "barnbarnbarnbarn', etc, but IIRC combi...

And in your case, if it's 8 lower case, the mask would be ?l?l?l?l?l?l?l?l, using attack mode 3 (-a 3), so something like: [hashcat executable] -m 2500 -a 3 myfile.hccap ?l?l?l?l?l?l?l?l

Yep. The only way to make real progress on it would be if multiple teams with lots of cards all cooperated. Which would itself be pretty cool, IMO.
