Example 61 with ObjectInputStream

use of java.io.ObjectInputStream in project XobotOS by xamarin.

the class SealedObject method getObject.

/**

     * @return the encapsulated object.
     * @throws IOException
     *             if deserialization fails.
     * @throws ClassNotFoundException
     *             if deserialization fails.
     * @throws IllegalBlockSizeException
     *             if the specified cipher is a block cipher and the length of
     *             the serialized data is not a multiple of the ciphers block
     *             size.
     * @throws BadPaddingException
     *             if the padding of the data does not match the padding scheme.
