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).

WebThe shift is (26-18)+4. This can be converted to all possible letters using the remainder function ie ( (26-o)+4) % 26, where o is the value of the most frequent letter. So if the most frequent letter is A=0, 26+4 % 25 = 4, which is the correct shift. Now, you can shift all the characters as explained above.
