> sniff the events before they are encrypted through the network

Uhh, this is confusing as written. But there are cheating hacks which allow you to see extra data that is sent to your client in-game, such as the entire map and your's and your opponents production queues. And while I'm not sure if this is what you were asking: "sniffing" events from other clients which haven't been sent to the blizzard server is not possible, because they're delivered to your client via the blizzard server (it's not P2P).

It's a combination of two things: 1) A customized UI layout for replays called "GameHeart" and 2) a custom SC2 game mod called "GameHeart" -- you can use the UI layout for ladder games which weren't created as custom games with the GameHeart mod, but for that replay you'll miss out on features like the drone kill counter and income graph vs. time for which the data is generated by the game mod.
