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 would become B, and so on. The method is named after Julius Caesar, who used it in his private correspondence.

This tool not only provide Caesar cipher shitf 13, but also provide other shitf ,you just need input the number in shift input, Click "Encrypt" is OK.

The action of a Caesar cipher is to replace each plaintext letter with one fixed number of places down the alphabet. This example is with a left shift of three, so that a E in the plaintext becomes B in the ciphertext.
