📝 One-Time Pad Encryption Workshop

November 30 @ 10:30 am - 11:30 am
A one-time pad encoder/decoder sheet, with two 36x36 grids of letters and numbers, with the following text at the bottom right: There's no space character, so we'll use 0 (zero) instead. When digits appear in your cleartext message, skip the surrounding Os that would normally indicate spaces. Examples: MEETOATOPARK7PM CALLOCASEY2156823032 Pad the end of your message with Os to obscure the length. If your message ends with a digit, you can pad the beginning instead to avoid ambiguity. ALLOCLEAROFORONOW000 (padded to 20 characters)

Join us for a workshop on one-time pad encryption! We’ll walk you through a technique for sending truly private messages without a computer, using 6-sided dice to generate random numbers. We’ll use an encoder/decoder sheet that fits on a single sheet of paper and can be recreated from memory.
