Keyed Caesar Cipher

The Keyed Caesar cipher is a variation to the standard Caesar cipher (shifting the letters by 13). In a keyed version, the alphabet is "keyed" by using a word and those letters are moved to the front of the alphabet and the rotation is performed.

Example: If the keyword was "zebra", the alphabet would look like this:

ZEBRACDFGHIJKLMNOPQSTUVWXY
You must enter the message.

Caesar Shift (1-25)
You must enter the encryption key.
