Thanks for the comments. I am reading the handbook on the enigmail website
and it really looks like a easy thing to do IF I was to use a personal email,
instead of a Tor based one (or one that I wanted to access through Tor to
protect my identity).
After reading a little bit more on Tor project homepage, it seems like mixing
GPG and Torbirdy is not a good idea (it will not work most of the time,
unless curl is also installed, and the version on the reps is not the
recommended one).
So, I guess my plan of using Icedove GUI will not be the best solution.... =S
Is there any other GUI for GPG in GNU/Linux? I understand using the command
line would also work, but I would prefer something with a GUI if possible.
Anyway, how would it work through the command line? I mean:
1. How would I tell the system "encrypt this text with that particular key so
I can send it to that person" (without ever connecting to the internet even
if a connection is present);
2. How would I say "Take this text here and unencrypt it for me, using this
particular key" (in case I had two keys for different email accounts);
Thanks!
