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 This is the beginning of asymmetric cryptography for this series of posts, so if you are just now beginning to follow along
Introduction In 1976, Whitfield Diffie and Martin Hellman introduced to the world the concept of public key cryptography also known as asymmetric cryptography.
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
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
Brief History In 1997, the National Institute of Standards and Technology (NIST) called to replace the DES. By this time DES was considered
Introduction Today we won’t actually learn about any new math concepts or algorithms. Instead, we will build upon what we have already. Particularly
