The only thing that seems remotely interesting is the "private key" part - I don't know Clojure but it doesn't seem like that's it.

They backported it to v0.45x and those changes don't seem to be included: https://github.com/metabase/metabase/compare/v0.45.4...v0.45...

aka, It isn't checked in to source control publicly yet. Interesting.

I tried to "decompile" the jars and loop over the files but it didn't yield much/wasn't clean enough to be of help.
