Last month, Bruce Schneier and I announced a public cryptographic
challenge: help figure out how to create ciphers and other privacy
applications for my code-wheel wedding rings, designed by Bruce and
created by Isabel Rucker.
Out of the submissions, there were a couple dozen that were really
strong contenders, and Bruce picked two to receive the winner and
My wife and I will take great pleasure in using both ciphers to
communicate in private!
Thanks, guys — your prizes are in the mail (and thanks to everyone who
contributed suggestions to this!).
