Codebreaking stories! Biafran War ciphers, secret diaries, and ciphers from the Vatican

These fascinating talks come from the 2022 Cryptologic History Symposium which was held virtually this year.

In this session, you'll learn about how ciphers from the Biafran War (or Nigerian Civil War) were broken, how an NSA cryptographer helped a family decipher mysterious diaries, and how a codebreaker used modern technology to decrypt centuries-old ciphers from the Vatican.
