The History of Codes and Cryptography— From Caesar Cipher to Quantum Encryption
<p>The history of codes and cryptography is a fascinating topic that spans thousands of years and involves many different methods and technologies. I have <em>wanted</em> to write on this topic for quite some time now but couldn’t complete it due to other projects at hand. Many people on individual basis and even companies use cryptographic techniques for various reasons from protecting sensitive data and preventing espionage to enabling the creation and exchange of cryptocurrency and other digital assets.
