I don't know how to use Password and Keys in Ubuntu 11.10 , what is the exactly use of this application , and how can we use this for encrypting files?
Please also explain about ssh keys and gpg keys?
I read help from application but its doesn't go in my mind what it is all about. I have found one interesting link here. It has helped me some but I still I have doubts.
Kindly make me understand in simple and short way .
