WebCaesar Cipher Overview; The Caesar Cipher is a simple substitution cipher that shifts letters of the alphabet by a fixed number of positions (Julius Caesar reportedly used a shift of 3). For example, if the shift is 3, 'A' would be replaced with 'D,' 'B' would become 'E,' and so on (Singh, 1999). Reference: Singh, S. (1999). WebIn 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.
