isAuthorizedKey

public abstract boolean isAuthorizedKey(com.maverick.ssh.components.SshPublicKey key,
                                        Connection con)

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 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.

Parameters:

key - SshPublicKey

sessionid - byte[]

authenticationProvider - AuthenticationProvider

Returns:

boolean true if the key is an authorized key, otherwise false
