Retrieves an immutable collection of the supported mechanisms.

Returns:

the supported mechanisms

worked

public static void worked(@NonNull
                          org.ietf.jgss.Oid mechanism)

Report that this mechanism was used successfully.

Parameters:

mechanism - that worked

failed

public static void failed(@NonNull
                          org.ietf.jgss.Oid mechanism)

Mark the mechanisms as failed.

Parameters:

mechanism - to mark

resolve

public static java.net.InetAddress resolve(@NonNull
                                           java.net.InetSocketAddress remote)

Resolves an InetSocketAddress.

Parameters:

remote - to resolve

Returns:

the resolved InetAddress, or null if unresolved.

getCanonicalName

@NonNull
public static java.lang.String getCanonicalName(@NonNull
                                                         java.net.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 org.ietf.jgss.GSSContext createContext(@NonNull

Parameters:

mechanism - Oid of the mechanism to use

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