I don't use linux directly infact primarily use it through ssh. Now I remember sometime ago a friend I mine had sent me this ppk file for sshing into his box. I'm not 100% sure how he did it (which is why I'm here asking), but I do think it was a more secure means off using ssh over the internet.
I've had a look around and haven't came up with much so maybe one of you could help me. I just want to build a ppk key. I'm not sure whether it's as simple as that either like do I need to add key information in the config file for sshd or what?
Any help would be great!
