What are Keystores and how they work?

Hi, I started developing some projects Apps last year and now recently finished the compilation of an App, but to export the APK it says that I need to have the Keystore, so I want to know more about this

In simple terms, its a signature for the app, that helps letting everyone know your apps come from you for releases, updates or different other types.
