Crytography Links

The following links were shown during Stuart Reges's cryptography talk:

• confederate cipher disk, available for purchase through nonprofit associated with the US National Parks

• enigma machine for sale on ebay (link likely to expire soon)

• NSA education links (see especially learning units)

• NSA CryptoKids, "fun" site (perhaps a bit scary), interesting list of high school and college programs

• Java BigInteger class: check out isProbablePrime, nextProbablePrime, modPow

Wikipedia is a great source of information about cryptography:

• history of cryptography

• scytale: Spartan encryption device

• Caesar cipher: simple basis of early cryptography

• Vigenère cipher, a polyalphabetic cipher

• German Enigma Machine

• RSA encryption

• PGP: Pretty Good Privacy

• Shor's Algorithm, which would break RSA using a quantum computer

• quantum computing

• RSA factoring challenge
