A simple encryption system, for example, is the Caesar cipher.

The Caesar cipher can be easily broken even in a ciphertext-only scenario.

Using methods similar to those used to break the Caesar cipher, the letters in the ciphertext can be discovered.

Caesar ciphers can be found today in children's toys such as secret decoder rings.

To make a message secret with the Caesar cipher, each letter in the message is changed using a simple rule: change by three.

It is a variant of a Caesar cipher.

The Caesar cipher is one example of a substitution cipher.

Some classical ciphers (e.g. the Caesar cipher) have a small key space.

ROT13 is an example of the Caesar cipher, developed in ancient Rome.

Another is the Caesar cipher, in which each letter of the alphabet is shifted by a certain number of spaces.

A construction of 2 rotating disks with a Caesar cipher can be used to encrypt or decrypt the code.

As with all single alphabet substitution ciphers, the Caesar cipher is easily broken and in modern practice offers essentially no communication security.

The Romans knew something of cryptography (e.g., the Caesar cipher and its variations).

The Caesar cipher is a substitution cipher: each letter is replaced by another.

Creative Writer uses a Caesar cipher, which simply involves substituting a letter in the text by one a few places down the alphabet.

For example, a Caesar cipher can be solved using a single letter of corresponding plaintext and ciphertext to decrypt entirely.

Often, the language is a simple shift in the alphabet, a letter or two forwards or backwards (See Caesar cipher).

All polyalphabetic ciphers based on Caesar ciphers can be described in terms of the tabula recta.

A monoalphabetic substitution cipher such as the Caesar cipher can easily be broken, given a reasonable amount of ciphertext.

Simple forms of cryptography that people can do are Caesar ciphers and Straddling checkerboard, but there are lots more.

At the end of every episode of the cartoon series Gravity Falls, during the credit roll, there is a hidden +3 Caesar cipher message.

The Caesar cipher is the Affine cipher when since the encrypting function simply reduces to a linear shift.

A Caesar cipher with a shift of one is used on the back of the Mezuzah to encrypt the names of God.

Provenzano used a version of the Caesar cipher, used by Julius Caesar in wartime communications.

Kahn (1967) describes instances of lovers engaging in secret communications enciphered using the Caesar cipher in The Times.
