Subject: Re: CUDA multi-device support (was: John-dev over GPUs)

Hello,

I was attempting to commit my current changes to git repo but I failed to
do so. Attempting to commit changes over HTTPS gave me HTTP 403 error.

error: The requested URL returned error: 403 while accessing
https://github.com/magnumripper/JohnTheRipper.git/info/refs
fatal: HTTP request failed

Changing the URL to ssh gave me an Permission denied (publickey) error.

Regards,
Junaid
