Decrytion is really easy too. We again make up the Mixed Square using the keyword, and then use the pairs of numbers to locate the plaintext letter in the grid, remembering the
We shall decrypt the message "42342115532354 23423241 23454224113123" using the keyword polybius.
First we must generate the Mixed Square in exactly the same way as we did before.
The Mixed Square using keyword polybius
Now we look at pairs of letters in turn. So "42" represents "a", "34" is the plaintext letter "n" and "21" is "o". Continuing in this way we get the plaintext message "another easy example".
