Side note, automatically breaking up passphrases is a really tricky problem unless the person creating them was nice enough to capitalize each of the words. Part of this is due to poor input dictionaries. Heck even determining keyboard combos is not exactly straightforward since you'd be surprised how many real words follow a partial keyboard walk. If you are looking for more experimental work, you can check out my pcfg guess generator at: https://github.com/lakiw/pcfg_cracker It's still *very* much in development so unfortunately it doesn't support longer cracking sessions at this moment. That being said, the training program breaks down a lot of statistics about the training password set that you might be able to use. It doesn't currently display them to the screen so you'll need to dig into the rules directory yourself. If you do use it please feel free to give me feedback and I apologize in advance for my horrendously late replies :) Matt On Sun, Jun 12, 2016 at 4:26 AM, Patrick Proniewski <patpro@...pro.net> wrote: > Hi, > > On 11 juin 2016, at 17:09, Michal Špaček wrote: > > > You can also try DigiNinja's Pipal: > https://digi.ninja/projects/pipal.php > > > Thanks, it looks interesting.
