public SealedObject (Serializable object, Cipher c) throws IOException, IllegalBlockSizeException

Constructs a SealedObject from any Serializable object.

The given object is serialized, and its serialized contents are encrypted using the given Cipher, which must be fully initialized.

Any algorithm parameters that may be used in the encryption operation are stored inside of the new SealedObject.

object    the object to be sealed; can be null.
c    the cipher used to seal the object.

NullPointerException    if the given cipher is null.
IOException    if an error occurs during serialization
IllegalBlockSizeException    if the given cipher is a block cipher, no padding has been requested, and the total input length (i.e., the length of the serialized object contents) is not a multiple of the cipher's block size
