Caesar Cipher Encode Caesar Cipher Decode How Caesar cipher works? This encoding and decoding is working based on alphabet shifting & transforming the letters into numbers . For example, Caesar cipher using a left rotation of three places, equivalent to a right shift of 23 as given below. ...
Cryptography - Caesar Cipher - So the next cryptographic algorithm is Caesar Cipher. In this chapter we will see what exactly Caesar Cipher is, how it works and also its implementations with different techniques. So let us deep dive into it.

The Caesar cipher is an ancient encryption algorithm used by Julius Caesar. It encrypts letters by shifting them over by a certain number of places in the alphabet. We call the length of shift the key. For example, if the key is 3, then A becomes D, B becomes E, C becomes F, and...

Secret key Cryptography Public key cryptography Hash Functions We discussed about the above techniques earlier in theCryptography basicsarticle. One simple and basic method to encrypt a message is using Caesar’s cipher. It is a very simple form of encryption, where we take letters one by one fr...
Caesar Cipher This Scheme was first proposed by Julius Caesar, cryptography is used since that time. In this Substitution cipher technique, each character of the plaintext message will be replaced by another character, symbol or number. Caesar cipher is another example of a substitution cipher wher...
