pcfg-go v0.6.0-dev (upcoming release)

While testing hashcat's new -a 4 PCFG mode with different hash lists and Rules trained with pcfg-go, atom (https://github.com/jsteube) mentioned something to me that I couldn't shake: “that needs a fast trainer”.

But, pcfg-go was already fast, right? How much faster did it need to be?

I was determined to find the answer to this question and pored over possible optimizations in pcfg-go.

The result? Let's first back up a minute to run a few comparisons.

The original Python3 pcfg_cracker trainer.py took 13m21s to train rockyou.

pcfg-go v0.5.3 brought rockyou training down to 2m38s.

And finally, pcfg-go v0.6.0-dev brings rockyou training down to 14.8s.

Yes, from 13m21s to 14.8s. Now, that's a fast trainer. 😎
