B4J Question B4JPackager: "Server" and "security" folder


Licensed User
As I've understood the packager creates a build folder with all needed components to run the B4J-App " standalone" like libs, etc. I've seen some server and security folders. What does these contain?

PS: I use encryption (RSA and AES). Does the "security" folder come from these components? And maybe the "server" folder from the Network functions I use?
