You can decrypt keys in wireshark once you have the key, you can also provide a key to wireshark to decrypt streams on the fly using said key.

Thanks, I'd been wondering this in the back of my head for a while, last time I searched for some reason I couldn't find much.

edit: Now that I see the wiki, I remember correctly that the version of Linux I was using didn't work with this feature in the GUI. Maybe I'll look for the CLI version again soon.
