As others have said, they're all dev-only keys for dev units. They've been public for years now, since well before gateway 1.0 even.
For the record, WulfyStylez is right(as she often/usually is). ryanrocks462 just repackaged the original 7z file into a zip file. I believe they were on anonfiles or something like that.

what 3DSGuy said about keys at the time:

I guess if you are really interested in keys that have been "public" for sometime but not wildly discussed you might want to checkout the header files in Project_CTR. (Again, if memory not incorrect(yuck double negative), stuff 3DSGuy was working on).
