Indeed, I have been trying to search for answers in the Tor Project website.
But my questions here deal directly with something else (though I admit I got
a little sidetracked at a point).
I need to know if I can use a program to:
Import a public key file, without connecting to the web;
Choose to encrypt a text with a different key;
Export my own keys (again never connecting to the web);
Make the whole encryption/unencryption process in my computer;
Protect/hide the keys that I have in my computer;
Preferably with a GUI;
I have investigated some alternatives (seahorse, GNU Shell, GPA, etc) but all
of them have been giving me some headache.
So, I am inclined to use the combination of
Tor+Thunderbird/Icedove+Enigmail+Torbirdy, but I know that can be insecure at
some times.
