Salty FiSH

For demonstration purposes only.

Includes a mechanism that continuously salts every message with extended-range Unicode characters, then removed once received on the other side, and verifies the message matches the $nick of the sender.

Where $'s are random unicode characters:

fanfare > Message
fanfare > $M$e$s$s$a$g$e fanfare
fanfare > ECB encrypted
fanfare > ECB decrypted
fanfare > $M$e$s$s$a$g$e fanfare
fanfare > Message fanfare ($'s are removed)
fanfare > Message $nick = fanfare (names match)
fanfare > Message
