Caesar Cipher

The objective is to demonstrate character/ symbol frequency distribution analysis (reference to the English language) on 2 vintage ciphers, namely Caesar cipher (a mono-alphabetic substitution cipher) and the Vigenere cipher (a poly-alphabetic substitution cipher).Under the symbol frequency...

This function uses frequency analysis to attack and decode messagesencoded using a /substitution cipher/ which exchanges each letter of thealphabet for another. Unlike the famous "Caesar Shift" cipher, which"shifts" the letters of the alphabet along by a certain amount, givingjust 26 possible...
