I came up with a neat little cipher that I'm calling the dual key cipher. The basic premise is that there are two cipher keys that, when used together can decode the cipher text against a given alphabet. Here is a basic example.



Key 1: CAT
Key 2: DOG
Alphabet: ABCDEFGHIJKLMNOPQRSTUVWXYZ
Cipher Text: ISA


The result would be:




HEN




Can you solve for this one? Bonus points for showing your work.



Puzzle 1 
Key 1: FISH
Key 2: DUCK
Alphabet: ABCDEFGHIJKLMNOPQRSTUVWXYZ
Cipher Text: ZUBG


Additional (off-topic) questions: Does anyone know if this type of cipher exists and if it has an official name? I've developed an algorithm that does this at a massive scale and wanted to know if anyone finds it interesting. Here is a somewhat more difficult version using my algorithm.



Puzzle 2 
Key 1: Chocolate
Key 2: Strawberry
Alphabet: abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ
Cipher Text: lmqgtbeyVXPERdpbX



Hint: The space between "z A" is part of this "alphabet".

          - The result will be equal to deciphering the Cipher Text with Passphrase of Key 3




          A note for the alphabets:




          Instead of using simple order from A to Z, we can change the order with specified Alphabet. But deciphering this needs a computer program or some works with hands.. I'm sorry I'm too lazy to solve the Puzzle 2 because of this.. ><
