##Welcome to the pcfg_cracker wiki!
- Incorporation of John the Ripper's Markov brute force is currently in development. Working PoC in Development branch.
- Currently modifying the back-end guess generation to standardize how it works with other modeling options like JtR Markov
- Biggest feature that hasn't been ported over from previous PCFG cracker is the use of custom per-session dictionaries
- Will likely get to that when I revisit the training program to allow updating dates, names, etc for a particular target
- Unlikely to get around to this in the next several months. If you are interested in helping I'd be very interested!
- Does not have the ability to stop/restart cracking sessions.
- This is a hard problem to solve for a general purpose grammar
- It's needed though so will continue to periodically look into it
- Currently it takes around a day to generate a billion guesses
- This is slow but....
- That billion guesses will likely crack about 70% of similar web passwords so in a ways that is pretty good
- I'm hopeful with probability smoothing a re-working the back-end guess generation will speed things up significantly
