Does this mean a program can be written to generate all possible api keys and upload to github thereby revoke everyone's access?

They are designed to be long enough that it's entirely impractical to do this. All possible is a massive number.

That's true tho... possible, but impractical.

Only possible if you are unconstrained by time and storage.

		Not only you, but GitHub too, since you need to upload. Storage is actually not much of a problem (on your end): you can just generate them on the fly.
