NAME
       Tspi_Data_Unbind - Decrypts data that has been bound to a key

SYNOPSIS
       #include <tss/platform.h>
       #include <tss/tcpa_defines.h>
       #include <tss/tcpa_typedef.h>
       #include <tss/tcpa_struct.h>

       TSS_RESULT Tspi_Data_Unbind(TSS_HENCDATA hEncData,	      TSS_HKEY hEncKey,
				   UINT32*	pulUnboundDataLength, BYTE**   prgbUnboundData);

DESCRIPTION
       Tspi_Data_Unbind  decrypts the encrypted data blob exportedfrom the data object used in Tspi_Data_Bind. The encrypted data blob must be im-
       ported to the object addressed by Tspi_SetAttribData before calling this method.

PARAMETERS
   hEncData
       The handle of the data object which contains the encrypted data.

   hEncKey
       Handle to the key object addressing the private key which is used to decrypt the data.

   pulDataLength
       Receives the length of the data at the parameter prgbUnboundData.

   prgbUnboundData
       Receives a pointer to a buffer containing the plaintext data.

RETURN CODES
       Tspi_Data_Unbind returns TSS_SUCCESS on success, otherwise one of the following values is returned:

       TSS_E_INVALID_HANDLE
	      hEncData or hEncKey is not a valid handle.

       TSS_E_INTERNAL_ERROR
	      An internal SW error has been detected.

       TSS_E_BAD_PARAMETER
	      One or more parameters is bad.

       TSS_E_INVALID_ENCSCHEME
	      Invalid encryption scheme.

       TSS_E_ENC_INVALID_LENGTH
	      Invalid length of data to be encypted.

       TSS_E_ENC_NO_DATA
	      No data to encrypt.

       TSS_E_ENC_INVALID_TYPE
	      Invalid encryption type.
