So, you send encrypted emails to your friends, with #GnuPG. What happens, if you have a #Government #Trojan, on your online device, which you can't detect?

A solution to this problem, is to send/receive encrypted #SMS from a device, which is not connected to the #Internet. Under Linux, you can archive this by installing #modem-manager-gui, with apt-get. Then you only need a surf stick, like a #D-Link DWM 222 and a small portable device, like a #GPD MicroPC.

And as software, you can use #FPE (Format Preserving Encryption) with a base(x) encoder/decoder, with a line length set to 0. 

If the SMS is longer than 160 characters it will send multiple SMS.

And as SIM card one can purchase those cheap #Allnet flat cards, so that you don't have to pay for each SMS, you send.
