Seems the only secure thing these days is an offline machine that encrypts your messages, then passes them over your own protocol to a machine on the net (via serial port or something) and sends it. You have to be able to see what the trusted machine is sending and know it can't go doing extra stuff. For that machine probably best to use a microcontroller, because I've heard that desktop CPUs have potential radio modules in them. I guess you also need to use some steganography because they probably treat encrypted messages as a red flag.
yes, you also need a one time pad .....
and one that deletes the previously used keys
clearly you have an issue on how to "exchange" the pad, but given the storage size of current usb key, one pad will last a lifetime (for normal text messages)
I was helping someone transfer account passwords and made a list of random strong passwords (20 die rolls each) and mailed it to them. The letter never arrived. Very weird.
