Learning the old ways.

This doesn't have much to do with enigma, but I have been studying cold war era clandestine communication methods (one time pads, dead drops, etc...). As primitive as these skills may seem, in today's society of cell phones and 24/7 internet access, few people would consider that communicating with someone can still be done without the use of modern technology. In all honesty, simply writing a note on a piece of paper and handing it to someone can be the most secure method of communicating. Humans over the years have tried to create the newest and best technology to keep information secure, but they don't seem to realize that still to this day the only 100% unbreakable cipher is done with pencil, paper, and completely random numbers.
