WebThe study of enciphering and encoding (on the sending end), and deciphering and decoding (on the receiving end) is called cryptography from the Greek κρυπτός (kryptos), or hidden and γράφειν (graphia), or writing. If you don't know Greek (and not many of us do) the above letters could be a form of code themselves! WebIn cryptography, we use A=0 ... Z=25. This makes sense, because if a shift is 0 you can assume that the letters were shifted by 0, which means they were shifted by nothing. Any letter shifted by 0 is that letter. Think of it like addition: you are adding a number. Any number + 0 is that number, therefore A+0 is A, right?

WebIt is a 5 letter text. To break the ciphertext by brute force, you need to try all possibilities of keys and conduct computation for (26 x 26 x 26 x 26 x 26) = 26 5 = 11881376 times. That’s for a message with 5 alphabets. Thus, for a longer message, the computation grows exponentially with every additional alphabet.
