Caesar-cipher This code sample demonstrates how the Rotary-based Caesar cipher works to provide very basic encryption. Note that this is not a secure method of encryption, and should only ever be used ...

Overview In cryptography, a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a ...

So, for example, if you read an entire paragraph and notice that the letter D appears more often than any other, odds are that it used a Caesar cipher with a shift of 1 (making E a D in the code).

The Caesar Cipher is also a substitution cipher. This was said to have been used by Julius Caesar to encode messages to his generals. In the classic Caesar cipher the letters are shifted 3 places to ...
