The Diffie-Hellman key exchange (DHKE) is different then most of the cryptography we have been covering in this blog. That is because we

The shift cipher, or the better-known name the Caesar cipher named after Julius Caesar is one of the simplest encryption techniques. In fact for those

Introduction Today we won’t actually learn about any new math concepts or algorithms. Instead, we will build upon what we have already. Particularly

Brief History In 1997, the National Institute of Standards and Technology (NIST) called to replace the DES. By this time DES was considered

Symmetric cryptography is split into two types, stream ciphers, and block ciphers. Stream ciphers encrypt one bit at a time and block ciphers encrypt multiple

Introduction In 1976, Whitfield Diffie and Martin Hellman introduced to the world the concept of public key cryptography also known as asymmetric cryptography.

What is Cryptology? The Oxford Dictionary defines Cryptology as: “the study of codes, or the art of writing and solving them”. When some people think
