Examples of javax.crypto.SecretKeyFactory.translateKey()

javax.crypto.SecretKeyFactory.translateKey()
Translates the specified secret key into an instance of the corresponding key from the provider of this key factory. @param key the secret key to translate. @return the corresponding translated key. @throws InvalidKeyException if the specified key cannot be translated using this key factory.

        assertNull("Incorrect result", secKF.translateKey(null));
        secKF = new mySecretKeyFactory(null, null, null);
        assertNull("Algorithm must be null", secKF.getAlgorithm());
        assertNull("Provider must be null", secKF.getProvider());
        try {
            secKF.translateKey(null);
            fail("NullPointerException must be thrown");
        } catch (NullPointerException e) {            
        }
