Introduction to cryptography 

Cryptography has been around for a long time.

Alan Turing’s accomplishment during World War II in decoding the German Enigma cipher is often referred to as the greatest milestone in the history of cryptography. Cracking Enigma seemed an impossible task, however Turing built a device known as the Bombe that used logic to decipher the encrypted messages produced by Enigma. From mid-1940, German Air Force signals were being read and the intelligence gained from them helped the war effort.

Today, cryptography is at the heart of the worldwide communication network. WhatsApp, for example, uses end-to-end encryption to secure your messages, so that only you and the person you’re communicating with can read or listen to what is sent.

This Learning Path will give you a basic understanding of what cryptography is and how it works through symmetric ciphers, hash functions, asymmetric ciphers, and digital signatures.

You’ll also look at key exchange and management, different models of protection, and cryptanalysis
