Find the result of this dual key cipher
$begingroup$
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 results for both puzzles are:
BIRD
and an incomplete one:
vanilla ...
The cipher is a variant of:
Vigenere Cipher
But:
Instead of using 1 key, it uses 2 keys. The result can be found by original Vigenere Cipher by this step:
- Let Key 3 be equal to deciphering Key 2 with Passphrase of Key 1
- 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.. ><
