Tspi_TPM_GetAuditDigest(3)			     TCG Software Stack Developer's Reference				Tspi_TPM_GetAuditDigest(3)

NAME

       Tspi_TPM_GetAuditDigest - retrieve the audit digest.

SYNOPSIS

       #include <tss/tspi.h>

       TSS_RESULT Tspi_TPM_GetAuditDigest(TSS_HTPM	  hTpm, 	   TSS_HKEY	      hKey,
					  TSS_BOOL	  closeAudit,	   UINT32*	      pulAuditDigestSize,
					  BYTE**	  prgbAuditDigest, TPM_COUNTER_VALUE* pCounterValue,
					  TSS_VALIDATION* pValidationData, UINT32*	      ordSize,
					  UINT32**	  ordList);

DESCRIPTION

       Tspi_TPM_GetAuditDigest	 is used to retrieve the audit digest.	The audit digest may be signed or unsigned.  If the audit digest is signed
       (hKey is non-NULL) then the current audit digest, the current audit counter and, optionally, the hash of the audited  ordinal  list  and  a
       signature  are returned.  If the audit digest is not signed (hKey is NULL) then the current audit digest, the current audit counter and the
       full list of audited ordinals is returned.

PARAMETERS

   hTpm
       Handle of the TPM object.

   hKey
       Handle of the signature key object (the handle can be NULL).

   closeAudit
       A flag indicating whether or not to close the current audit digest after it is signed.  This parameter is ignored if hKey is NULL.

   pulAuditDigestSize
       Pointer to the size of the returned audit digest.

   prgbAuditDigest
       Pointer to a buffer that holds the returned audit digest.

   pCounterValue
       Pointer to a TPM_COUNTER_VALUE structure that holds the returned audit counter.

   pValidationData
       Pointer to a validation data structure.	The validation data structure provides external information required to compute the signature.	On
       input,  the  fields representing the ExternalData must contain an anti-replay nonce that will be used in the signing operation.	On output,
       this structure provides a buffer containing the data used to compute the validation data and a buffer containing  the  validation  data	(a
       signature generated by signing the data using the key referenced by hKey).  If this parameter is NULL then the TSS will perform the valida-
       tion.  This parameter is ignored if hKey is NULL.

   ordSize
       Pointer to the number of ordinals in the returned audited ordinal list.	This parameter is ignored if hKey is non-NULL.

   ordList
       Pointer to a buffer that holds the returned audited ordinal list.  This parameter is ignored if hKey is non-NULL.

RETURN CODES

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

       TSS_E_INVALID_HANDLE

       TSS_E_BAD_PARAMETER

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

CONFORMING TO

       Tspi_TPM_GetAuditDigest conforms to the Trusted Computing Group Software Specification Version 1.2

Tspi_Data_Unseal(3)				     TCG Software Stack Developer's Reference				       Tspi_Data_Unseal(3)

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
