NAME

       Tspi_Data_Unseal - dencrypt data encrypted by Tspi_Data_Seal() only if it was encrypted on the same platform and under the current configu-
       ration.

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_Unseal(TSS_HENCDATA hEncData,	       TSS_HKEY hKey,
				   UINT32	pulUnsealedDataLength, BYTE**	prgbUnsealedData);

DESCRIPTION

       Tspi_Data_Unseal reveals data encrypted by the Tspi_Data_Seal only if it was encrypted on the same platform and the current  configuration.
       This is internally proofed and guaranteed by the TPM.

PARAMETERS

   hEncData
       Handle of the data object which contains the sealed data.

   hKey
       Handle to the key object addressing the nonmigratable key which is used to decrypt the data.

   pulUnsealedDataLength
       The length (in bytes) of the prgbUnsealedData parameter.

   prgbUnsealedData
       On successful completion of the command, this parameter points to a buffer containing the plaintext data.

   hPcrComposite
       Handle  of  the	PCR Composite object specifying the PCRs which are part of the sealed data blob. Set to NULL, if the encrypted data should
       only be bound to the system and PCRs are not of interest.

RETURN CODES

       Tspi_Data_Unseal returns TSS_SUCCESS on success, otherwise one of the following values are returned:

       TSS_E_INVALID_HANDLE - Either hEncData or hKey is not a valid handle.

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

CONFORMING TO

       Tspi_Data_Unseal conforms to the Trusted Computing Group Software Specification version 1.1 Golden

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 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.
