adding channel keys

how do i add other sat keys to my box?

i use both oscam and cccam but there was a channel a mate told me about and said i need to add a key every month

i cant seem to find a plugin for entering the key? or do i do it on my server?

cheers for the post, i have downloaded all 3 to test. gone to a few channels and are scrambled
i have made sure file path is usr/keys the sofcam.key shows as a reg file not just blank?

rebooted my box as well

when i go to edit it or rename it keeps wanting to open it up as a reg file?

thanks the tk one works
