WebAlthough Pigpen might be regarded as a fun cipher to use, it offers almost no cryptographic security at all. Its use of symbols instead of letters in no way impedes cryptanalysis, and this cipher is not otherwise different from any other simple monoalphabetic substitution cipher. 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?
