[Trisquel-users] email client - exploits - which repo programs are safe?

[emrobin2]

Hello,
Interest in learning more about encryption keys and utilizing encryption for  
email messages and other forms of contact lead me to view discussions  
regarding fairly recently revealed exploits attacking encrypted messages  
tricking email clients to expose and even transmit decrypted portions of what  
was meant to be hidden.

If it is presumed that some progress has been made in countering the known  
exploits, which email programs and 'companion' encryption software available  
from the official Trisquel repos are vetted as reasonably safe to use in  
light of the problems?

It seems that the safety will also be directly affected by any communication  
partner in that that individual(s) have also taken appropriate/effective  
precautions to avoid exposure.

Thanks.

(Trisquel 8.0; no email client established; no email client linked encryption  
software set up; no link to the outside world other than through this  
browser?)
