/*
 * NAME
 *	Tspi_Data_Unbind06.c
 *
 * DESCRIPTION
 *	This test will verify that Tspi_Data_Unbind can encrypt and decrypt
 *	some data using the OAEP Encryption Scheme.
 *
 * ALGORITHM
 *	Setup:
 *		Create Context
 *		Connect Context
 *		Create Key Object
 *		Create Enc Data
 *		Set Attrib Uint32
 *		Load Key By UUID
 *		Bind Data
 *
 *	Test:
 *		Call Data_Unbind then if it does not succeed
 *		Make sure that it returns the proper return codes
 *		Print results
 *
 *	Cleanup:
 *		Free memory related to hContext
 *		Close context
 *
 * USAGE
 *      First parameter is --options
 *                         -v or --version
 *      Second parameter is the version of the test case to be run
 *      This test case is currently only implemented for v1.1
 *
 * HISTORY
 *      Kent Yoder, shpedoikal@gmail.com, 04/14/05
 *
 * RESTRICTIONS
 *	None.
