Sierra Vista Public Library: Secret Codes & Ciphers – Playfair Ciphers & Steganography

Codes and Ciphers have been used to conceal information for thousands of years and people have found thousands of ways to pass secret messages.

This program touches on some of history’s most common codes and ciphers and teaches kids ages 9+ what they are and how to use them. Registration is required for each individual date.
