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>
       #include <tss/tss_typedef.h>
       #include <tss/tss_structs.h>
       #include <tss/tspi.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 imported
       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.
