The Diffie-Hellman key exchange (DHKE) is different then most of the cryptography we have been covering in this blog. That is because we
Symmetric cryptography is split into two types, stream ciphers, and block ciphers. Stream ciphers encrypt one bit at a time and block …
The shift cipher, or the better-known name the Caesar cipher named after Julius Caesar is one of the simplest encryption techniques. In …
Modular Arithmetic An important question and one that I kept asking if I should dedicate a post to modular arithmetic …
The Substitution Cipher We will discuss one of the simplest ciphers, the substitution cipher. This cipher has a lot of …
What is Cryptology? The Oxford Dictionary defines Cryptology as: “the study of codes, or the art of writing and solving them”. When …
Introduction The Data Encryption Standard (DES) was proposed in the early 1970s by IBM, who based the design of the cipher on an
Modular Arithmetic An important question and one that I kept asking if I should dedicate a post to modular arithmetic is “Why is
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
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
