A flag was cut into pieces, and each piece was placed on a different image PNG, JPG, and others.

All of them were packed into an archive, but not before their extensions were stripped. The archive itself was then encrypted with a 2-byte XOR password. The key and the list of file extensions were sent through a separate channel and all we managed to intercept was the encrypted blob.

See if you can solve it.
