Purge rule?

[mastercracker]

Thanks atom. What do you guys think about this solution: for unsalted hashes, run hashcat with the wordlist and purge rules. This should not be costly and finish in a reasonable time. For salted hashes or heavy iterated hashes, uses hashcat with the purge rules in stdout and use it to pipe in oclhashcat. Would this speed the cracking over hashcat alone?
