The following message was encrypted using a Caesar cipher with a key of 2:

fghgpf vjg ecuvng

What is the plaintext message?

  • invade the castle
  • defend the castle
  • defend the region
  • invade the region

Explanation: The Caesar cipher was a simple substitution cipher. In this example, if the key is 2, the letter d was moved two spaces to the right, resulting in an encoded message that used the letter f in place of the letter d. The letter g would be the substitute for the letter e, and so on. So, the resulting plaintext is f=d, g=e, h=f, g=e, p=n, f=d, v=t, j=h, g=e, e=c, c=a, u=s, v=t, n=l, g=e.​
