The Simple Substitution Cipher

The basic idea is to exchange each of the letters of a message with letters from a ciphertext alphabet:

ABCDEFGHIJKLMNOPQRSTUVWXYZ ...Plain Text Alphabet

MADCOWBEFGHIJKLNPQRSTUVXYZ ...Cipher Text Alphabet

For example, "D" would become "C" and "N" would become "K"

the message "flea bag" would become "wiom amb"

The keyword 'madcow' was placed below the standard alphabet, and the remaining letters were placed, in order, after the keyword.
