Description copied from interface: PublicKeyAuthenticationProvider

Check the supplied public key against the users authorized keys. The actual verification of the key is performed by the server, you only need to return a value to indicate whether the key is authorized or not. You can obtain the username, home directory, group or remote socket address from the com.sshtools.common.auth.server.PasswordAuthenticationProvider instance.

If your authorized key database is kept on the native file system you can obtain and initialize an instance as follows:

 NativeFileSystemProvider nfs = (NativeFileSystemProvider) authenticationProvider
                .getContext().getFileSystemProvider().newInstance();
 
 nfs.init(sessionid, null, authenticationProvider.getContext());
 

Don't forget to close any file handles and the file system once you've done accessing files.
