Interface jnfs.security.Authentication

public interface interface Authentication
The server-side Authentication issues challenges and verifies if they have been met successfully. For efficiency, the file system may also ask the Authentication to issue tokens for a particular user. Tokens (like challenges) are stored with user information upon generation.
