WebShift Cipher. The shift cipher is a classical cryptosystem that takes plaintext and shifts it through the alphabet by a given number of letters. For example, a shift of 2 would replace all A's with C's, all B's with D's, etc. When the end of the alphabet is reached, the letters are shifted cyclically back to the beginning. WebExplain the concept of a Caesar cipher to a friend, or have them read the background section of this activity. Write down the alphabet from A to Z.
