1) James Zolomon

He has military training from the War of the Americas, so he can feasibly know that code. Zoom is torturing his dad, and shows him just how much better he is.

2) The Real Jay Garrick

Berlanti said that they "wouldn't make Jay Garrick a villain - keep watching!", so perhaps Hunter Zolomon stole his identity from someone else, maybe even someone who doesn't LOOK like Teddy Sears. Speculate this: the real Jay Garrick became the Flash, tried hiding his identity (by the way of face vibration) -> Hunter Zolomon kidnaps him, puts him into the anti-speeder cage, takes on both his name and his superhero identity, then moonlights as both "Jay the Flash" and "Zoom". Why doesn't anybody recognize that this man is not Jay Garrick? Well, maybe he just killed all relatives and friends of the Real Jay. Earth-2!Hunter IS a serial killer, after all.
