Steps to reproduce the behavior in the code:
Just open any protected pdf whose password is not 'userpw', in the example project of the package.

Expected behavior
Instead of throwing an error, we should receive information if password entered was incorrect. Throwing an error is not good practice for production apps.

Please look into this.
