A basic understanding of cyphers and cryptography is part of a solid foundation for anyone in the InfoSec field. Today we use crypto without much second thought, but cryptography, or the use of ciphers and codes to protect secrets, has been around for thousands of years. Until the early 20th century, encryption was done with pen and paper or simple mechanical devices. My Tabletop Cryptography talk is about the history of cryptography and cryptanalysis as well as fun with examples of crypto-puzzles that can all be completed without the use of modern infernal computing devices.
