You may be wondering why I am writing about symmetric encryption. Well, I realized recently, that I don’t know much about it, and in learning more about it, I decided to document what I have learned so far. Encryption can be summed up as a means of protecting our data…

Caesar Cipher is one of the simplest and most widely known encryption techniques . It involves shifting each letter in the message by a certain number of places in the alphabet. In this article, we will discuss the Caesar Cipher and how it can be implemented in C. Caesar Cipher The Caesar…

Author’s note: This solution has been rejected by the journal Cryptologia, and I am increasingly convinced of its validity. Here it is; you’ve been warned. Abstract: A geometric assembly of the symbols of Edward Elgar’s Dorabella Cipher is proposed, producing a rose-shaped key which is used in a systematic decipherment…
