EXAMPLES: WebA Caesar Cipher is a special kind of cryptogram, in which each letter is simply shifted a number of positions in the alphabet. It can easily be solved with the Caesar Cipher Tool. A ROT13 Cipher is similar to a Caesar Cipher, but with a fixed shift of 13 letters. It can easily be solved with the ROT13 Tool. Sample Cryptogram

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 type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. For example, with a left shift of 3, D would be replaced by A, E woul… WebIf you’ve seen the lesson on the one-time pad, you know that it is the ultimate shift cipher.

WebThe Caesar Cipher is one of the simplest symmetric encryption techniques, and of course, one of the easiest to crack. Since then, cryptologists have invented many more symmetric encryption techniques, including the ones used today to encrypt data like passwords.
