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.
