Missing default private key

I changed the lock_level from 0 to 1 to test it but now I can't changed it back because I'm missing the default private keys. I changed it without changing the default public keys. They should be in the github repository or am I missing something because I can't find them.
Thanks

The issue names no source file, test, or entry point. Start by locating the default public-key and private-key configuration in the repository and compare it with the lock_level behavior described; done means identifying how the default keys are provided or documenting the missing-key problem clearly.
