Constructor Detail


public KeyRep(KeyRep.Type type,
              String algorithm,
              String format,
              byte[] encoded)
Construct the alternate Key class.

type - either one of Type.SECRET, Type.PUBLIC, or Type.PRIVATE
algorithm - the algorithm returned from Key.getAlgorithm()
format - the encoding format returned from Key.getFormat()
encoded - the encoded bytes returned from Key.getEncoded()
NullPointerException - if type is null, if algorithm is null, if format is null, or if encoded is null
Method Detail


protected Object readResolve()
                      throws ObjectStreamException
Resolve the Key object.

This method supports three Type/format combinations:

the resolved Key object
ObjectStreamException - if the Type/format combination is unrecognized, if the algorithm, key format, or encoded key bytes are unrecognized/invalid, of if the resolution of the key fails for any reason
