I have built a multiprocessing password cracker (using a wordlist) for a specific function, it halved the time needed compared to using a single process.
The original problem being that it would show you the cracked password and terminate the worker, but the remaining workers would carry on until they ran out of words to hash! not ideal.
My new step forward is to use Manager.Event() to terminate the remaining workers, this works as I had hoped (after some trial and error), but the application now takes far longer that it would take as a single process, I'm sure this must be due to the if function inside pwd_find() but I thought I would seek some advice.
