As asking a friend and no amount of Googling yielded an answer, I figured I'd make an account and give this place a go.
I'm working on reverse engineering the server for a relatively old game with no network packets from when it was alive. The game only made partial use of SSL (don't know what for specifically), and nothing I send it seems to trigger any response. The game sends a packet via a TCP PSH after the connection is established, and Apache replies with a 400 Bad Request. If Apache doesn't send any error, the game will wait indefinitely for a response. Due to lack of environment variables in the data and a defining request (HTTP GET, SSL handshake, etc.) from the game, it's unclear as to what it's expecting. CGI scrips, digest authentication, nor anything I can think of matches the contents. Here's the packet dump. "Hub" is a special keyword that's referenced throughout the game binary relating to code files and directories:

Scanning it as a file will detect it as a .der certificate, and while its structure in general looks like a certificate, as far as I can tell via comparison, it is not. Perhaps someone with more knowledge knows what this is (and what "rt" is, below), or knows if this is some custom data. The following strings are also referenced in the game's binary that likely has some relation, with the first coming directly after the above ASCII ZG$o?:
