public static int[] getBuiltInDefaults ()

public static int[] getDefaults (String configName, EncryptionKey[] keys, Config kerberosConfig)

Retrieve the default etypes from the configuration file for those etypes for which there are corresponding keys. Used in scenario we have some keys from a keytab with etypes different from those named in configName. Then, in order to decrypt an AS-REP, we should only ask for etypes for which we have keys.

Parameters
configName
keys
kerberosConfig
Throws
KrbException

public static int[] getDefaults (String configName, Config kerberosConfig)

Retrieves the default etypes from the configuration file, or if that's not available, return the built-in list of default etypes.

Parameters
configName
kerberosConfig

public static EType getInstance (int eTypeConst)

Parameters
eTypeConst
Throws
KdcErrException

public static boolean isSupported (int eTypeConst, int[] config)

Parameters
eTypeConst
config

public static boolean isSupported (int eTypeConst)

Parameters

Parameters
