Let's take the "Crypto Bro" term and throw it in the shredder. Cryptography is cool, useful, and a big part of programming jobs. Cryptography has a long and fascinating history that spans thousands of years. It has been used to protect sensitive information, ensure the authenticity of messages, and facilitate secure communication. In this conference talk, we will explore the history of cryptography from its early beginnings with the Caesar cipher to modern techniques such as public key cryptography and JWT (JSON Web Token).
