Subject: Re: cryptocurrency mining fallback in JtR (was:
 Parallella: scrypt)

Hello,

>From my last mail, I have implemented a prototype version of cgminer
integration with JtR. This prototype gets the user, pass and address from
the JtR config file. I was checking the best way to integrate cgminer with
JtR and I think the best is use the API provided by cgminer, in order to
avoid add a lot of dependencies to JtR. We can add an option to JtR config
file that sets the path that Cgminer is installed and run it if the option
--miner is set. Using the API we can show information and enable/disable
GPUs.

Best regards,
Rafa.
