[Trisquel-users] Need help with GPG/Enigmail/Torbirdy

[gnuser]

Hello everyone,

Ok, so, I need to make sure that I don't screw up with my "anonymous  
encrypted email".
Basically, from what I understand one could install thunderbird/icedove,  
install enigmail and torbirdy, and use an email on Tor hidden service (like  
mailtor) to send and receive GPG encrypted and signed emails. Problem is,  
apparently torbirdy has still a few leaks, and so I would like to do  
something "different". I would like to use icedove to write and encrypt the  
emails in my computer and after that copy+paste the encrypted email in the  
webmail interface. Same for receiving emails, I would receive it encrypted,  
copy+paste inside thunderbird, and it would allow me to read the plain text.
However, I have not been able to find anywhere HOW to do it, because it would  
involve having the keys (both mine and the person I want to contact) in the  
computer but preventing the thunderbird/icedove from accessing the web.
Does anyone here with experience with GPG and Torbirdy can give me a hand? I  
know some people here (like lloydsmart) use GPG even here in the forum, can  
you guys teach me how to do it? Everything that I found so far is about using  
a direct connection. Or maybe that is actually the best way... I don't know.

THANKS IN ADVANCE =)
