Got all the classical analogies ready? Like key exchange = box with
padlocks being sent back and forth?

Does anybody have a good analogy for perfect forward secrecy? Maybe to use
code books and to burn old used copies? (after the explanation of OTP)

What about analogies for authentication? How about tamper evident seals +
padlocks as the analogy for TLS?

Which other topics are you planning to cover? Anonymity like with onion
routing, more advanced crypto like Zero-knowledge proofs and such?
