Method Detail

getSupportedMechanisms

@NonNull
public static Collection<Oid> getSupportedMechanisms()

Retrieves an immutable collection of the supported mechanisms.

Returns:

the supported mechanisms

worked

public static void worked(@NonNull
                          Oid mechanism)

Report that this mechanism was used successfully.

Parameters:

mechanism - that worked

failed

public static void failed(@NonNull
                          Oid mechanism)

Mark the mechanisms as failed.

Parameters:

mechanism - to mark

resolve

public static InetAddress resolve(@NonNull
                                  InetSocketAddress remote)

Resolves an InetSocketAddress.

Parameters:

remote - to resolve

Returns:

the resolved InetAddress, or null if unresolved.

getCanonicalName

@NonNull
public static String getCanonicalName(@NonNull
                                               InetSocketAddress remote)

Determines a canonical host name for use use with GSS-API.

Parameters:

remote - to get the host name from

Returns:

the canonical host name, if it can be determined, otherwise the unprocessed host name.

createContext

public static GSSContext createContext(@NonNull
                                       Oid mechanism,
                                       @NonNull
                                       String fqdn)

Creates a GSSContext for the given mechanism to authenticate with the host given by fqdn.

Parameters:

mechanism - Oid of the mechanism to use

fqdn - fully qualified domain name of the host to authenticate with

Returns:

the context, if the mechanism is available and the context could be created, or null otherwise

closeContextSilently

public static void closeContextSilently(GSSContext context)

Closes (disposes of) a GSSContext ignoring any GSSExceptions.

Parameters:

context - to dispose
