One Time Pad Cipher

Description

The One Time Pad cipher is a method of encrypting alphabetical messages.

 

How it works:

It works by converting each letter of the message into a corresponding number, such that:

Letters to Numbers chart
Letter Number
A 0
Z 25

 

 

 

Then converts each letter of a given key into a number in the same way.

Then it adds the number from the message and the number from the key together (numbers are from the letters at the same index).

To finalize, it converts the calculated numbers back into letters.

 

Example:

Let's take "codecup" as the message,

and "python" as the key.

this will result in "rmwlqhp" as the output.

 

Note:

Spaces are not encrypted, though they do count as an index in the string.

Question

If the output is "mbz akb hs ogdv" and the key is a list of letters in alphabetical order, starting at the same letter that the message starts with, what was the original message? (answer is in all lower case letters)
