Any reference to Caesar, emperor of Rome, or more generally to antiquity and the Roman Empire are clues. Caesar cipher is best known with a shift of 3, all other shifts are possible. Some shifts are known with other cipher names. Caesar cipher is applicable only to letters of the alphabet. There are, however, several solutions to crypt numbers:. Caesar Caius Iulius Caesar used this technique for some correspondences, especially military, for example with Cicerone shift of 3.

Caesar cipher is also known as Shift Cipher. This shifting property can be hidden in the name of Caesar variants, eg. Any 2-letter code that can give an association between a crypted char and the plain one see gramograms. ROT5 code for digits, the shift is 5 and reversible. Write the letter with rank R2 in the alphabet. The code was named after Julius Caesar who was born in BCE the first man which has testimonies like Suetonius proving that he used this type of substitution to protect his military communications.

The exact date of creation and its real author are unknown. Need Help?

The Caesar cipher, while reasonably effective in its Roman heyday, is now one of the easiest cryptographic codes to break. Breaking a Caesar cipher usually follows one of three scenarios depending on the amount of knowledge the attacking cryptanalyst has:.

In all of the proposed scenarios, assuming that the cipher relies on a simple numerical shift, the code can very easily be cracked using a brute force attack trying all possible shifts and determining which one works. In the case of a keyed Caesar cipher, matters become considerably more difficult, though still relatively easy to break.

In this instance there are two primary methods of breaking the code:. The Caesar cipher is one of the oldest forms of cryptography in recorded history, with instances stretching back long before it was first named. Nonetheless, the cipher finds itself named for, and consistently associated with, the famous Roman Emperor and General Julius Caesar. It was Caesar who reportedly used the cipher with a shift of three to encode military messages to his commanders while on a campaign.

Despite the presence of more complex codes, the cipher was likely favored by the emperors due to its simplicity.

The cipher was likely effective due to the illiteracy of many of those who would intercept them and a common misconception that the messages were written in a mysterious foreign language. Enforcing this assumption of security is the lack of evidence that any methods for solving substitution ciphers existed at the time, with the first instances of frequency analysis appearing in the middle east centuries after Caesar's death.

Despite its growing ineffectiveness in the modern era, the cipher would nonetheless remain in use by various groups for less vital communications such as by Jewish groups to encrypt the name of god on the mezuzah and later by people wishing to exchange messages in plain view by posting encoded passages in newspapers. Nevertheless, the last major use of the cipher for warfare was by imperial Russian forces in the first world war due to the common soldiers struggling to understand more complex encryption methods.

A choice that was found to be a failure as contemporary German and Austrian code-breakers were easily able to decipher any messages sent in the code. Regardless of being phased out well over a century ago, the Caesar cipher has not fallen out of use entirely. In a Sicilian mob boss named Bernardo Provenzano was captured by police due to his usage of an altered version of the Caesar cipher where letters were replaced by numbers after their shift.

Likewise in , a British counter-terrorist operation foiled a planned airline bombing due to the usage of an easily breakable Caesar cipher by the perpetrators in their internet communications.

Despite its lack of security in helping to send confidential communications by itself the Caesar cipher still has several applications today in a variety of fields.
