Explore how code breakers and spies influenced cryptography and explore the role it plays in modern secure communication.Is it possible to prove the security of encrypted data? Will every algorithm fail given sufficient time or computing power? On this course you will get an introduction to cryptography and cryptanalysis. From ancient examples of secret messages and the spies that cracked them to modern cryptographic applications, you will have the opportunity to explore the foundations of data security. During the course you will also get an opportunity to try encrypting data yourself by completing a cryptography and cryptanalysis challenge.
