public class Wrapping

extends Object

This example demonstrates the use of key wrapping introduced by Sun in their JCE 1.2.1 API.

The point of that API is basically to define a way to encrypt and decrypt keys instead of byte arrays. Internally this will usually we implemented simply by encoding the key and then encrypting the byte array and vice versa for decryption.

This example shows how this API can be used to easily exchange a symmetric content encryption key (e.g. Triple DES) using RSA and key wrapping. Note that key wrapping can be used to wrap public, private, and secret keys and that all symmetric ciphers and the RSA cipher support key wrapping in the IAIK JCE.
