Does a += which will bog the computer down for bodies of text longer than a few thousand characters. Does a cast number to character, so it will fail with anything but ascii letters.
WebThe Caesar Cipher is one of the simplest symmetric encryption techniques, and of course, one of the easiest to crack. Since then, cryptologists have invented many more symmetric encryption techniques, including the ones used today to encrypt data like passwords. Vigenère Cipher French cryptologists invented the Vigenère Cipher in the mid 1500s.
