Constructor Detail

KeyRep

public KeyRep(KeyRep.Type type,
              String algorithm,
              String format,
              byte[] encoded)

Constructs a new instance of KeyRep with the specified arguments. The arguments should be obtained from the Key object that has to be serialized.

Parameters:

type - the type of the key.

algorithm - the algorithm (obtained by Key.getAlgorithm()).

format - the format of the key (obtained by Key.getFormat()).

encoded - the encoded byte[] (obtained by Key.getEncoded()).

Throws:

NullPointerException - if type, algorithm, format or encoded is null .

Method Detail

readResolve

protected Object readResolve()
                      throws ObjectStreamException

Resolves and returns the Key object. Three KeyRep.Type|format combinations are supported:

• Type.PRIVATE | "PKCS#8" : returns a PrivateKey instance, generated from a key factory (suitable for the algorithm) that is initialized with a PKCS8EncodedKeySpec using the encoded key bytes.
• Type.SECRET | "RAW" : returns a SecretKeySpec instance, created with the encoded key bytes and the algorithm.
• Type.PUBLIC | "X.509": returns a PublicKey instance, generated from a key factory (suitable for the algorithm) that is initialized with a X509EncodedKeySpec using the encoded key bytes.

Returns:

the resolved Key object.

Throws:

ObjectStreamException - if the Type|format combination is not recognized, or the resolution of any key parameter fails.
