ASK HN: Most secure way to send a message from one place to another on earth

• anigbrowl 9y ago
  Simple way: Signal messaging Elaborate: one time pads, lasers bounced off lunar reflectors
  • enriquto 9y ago
    signal messaging and one time pads are essentially equivalent, the former being useful only for a few bits of information, and the later is able to use the whole bandwith

      I'm sorry, I meant Signal the encrypted chat application produced by Open Whisper.
• airbreather 9y ago
  Pre-arranged codes/signals where the signal contains none of the message. e.g. selling a certain item/s at a certain price on ebay means a pre-agreed action is to occur, to be simplistic. This does however require collusion prior.

  I think you need to set the scope better for the question. Easily usable by average Joe? Most secure using available for all technology / infrastructure?
