Do you plan to add other error types for the SE050 or could we also just call it SE050_ERROR?

[sosthene-nitrokey]

I don't see any other now. And indeed the error can include initialization errors.

Maybe it should be SE050_INIT_ERROR? I'm fine with either.

[robin-nitrokey]

As this is called InitStatus, I think we don’t need another INIT, but both options are fine for me.

[sosthene-nitrokey]

Ok!

I renamed it to SE050_ERROR.
