  • KeyRep

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

    Construct the alternate Key class.

    Parameters:

    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()

    Throws:

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

• Method Detail

  • readResolve

    protected Object readResolve()
     throws ObjectStreamException 

    Resolve the Key object.

    This method supports three Type/format combinations:

    • Type.SECRET/"RAW" - returns a SecretKeySpec object constructed using encoded key bytes and algorithm
    • Type.PUBLIC/"X.509" - gets a KeyFactory instance for the key algorithm, constructs an X509EncodedKeySpec with the encoded key bytes, and generates a public key from the spec
    • Type.PRIVATE/"PKCS#8" - gets a KeyFactory instance for the key algorithm, constructs a PKCS8EncodedKeySpec with the encoded key bytes, and generates a private key from the spec

    Returns:

    the resolved Key object

    Throws:

    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
