The Caesar Cipher, used by Julius Caesar around 58 BC, is a substitution cipher that shifts letters in a message to make it unreadable if intercepted. To decrypt, the receiver reverses the shift. Arab mathematician Al-Kindi broke the Caesar Cipher using frequency analysis, which exploits patterns in letter frequencies. 1. Because of the way you are correcting for out of range letters with code like letter = (char) (letter - 26); you'll have to do something to make sure your shift is not too large. } I would add this line to the beginning of your Encrypt function. shift %= 26; This will ensure that your shift is never larger than 26.Caesar Cipher Algorithm Program in C/C++. In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption —a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code.The key to the Pigpen Cipher is this easy to remember grid system.

One of the simplest examples of a substitution cipher is the Caesar cipher, which is said to have been used by Julius Caesar to communicate with his army. Caesar is considered to be one of the first persons to have ever employed encryption for the sake of securing messages. For a polyalphabetic cypher Brit explains that the length of the word is the key in a cracking the code. To find this you take letters at different intervals to build a subset of letters to analyze their frequency. i.e. start with the first letter …Decryption is a slightly different formula, d (x) = a-1(x - b) mod m.
