示例2: engineUnwrap
/**
* Unwrap a previously wrapped key.
*
* @param wrappedKey the key to be unwrapped.
*
* @param wrappedKeyAlgorithm the algorithm the wrapped key is for.
*
* @param wrappedKeyType the type of the wrapped key.
* This is one of <code>Cipher.SECRET_KEY</code>,
* <code>Cipher.PRIVATE_KEY</code>, or <code>Cipher.PUBLIC_KEY</code>.
*
* @return the unwrapped key.
*
* @exception InvalidKeyException if <code>wrappedKey</code> does not
* represent a wrapped key, or if the algorithm associated with the
* wrapped key is different from <code>wrappedKeyAlgorithm</code>
* and/or its key type is different from <code>wrappedKeyType</code>.
*
* @exception NoSuchAlgorithmException if no installed providers
* can create keys for the <code>wrappedKeyAlgorithm</code>.
