NAME
       Tspi_Hash_Sign - sign the hash data of an object with a signing 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_Hash_Sign(TSS_HHASH hHash,	       TSS_HKEY hKey,
				 UINT32    pulSignatureLength, BYTE**	prgbSignature);

DESCRIPTION
       Tspi_Hash_Sign signs the hash data of an object with a given signing key. The data must be
       set at the hash instance  associated  with  hHash  by  calling  Tspi_Hash_SetHashValue  or
       Tspi_Hash_UpdateHash.  The Tspi_Hash_Sign method allocates a memory block for the prgbSig-
       nature data. This memory must be released using Tspi_Context_FreeMemory.

PARAMETERS
   hHash
       The handle to the hash object instance whose hash value should be signed.

   hKey
       Handle to the key object which should be used for the signature.

   pulSignatureLength
       Receives the length of the signature data returned at the parameter prgbSignature on  suc-
       cessful completion.

   prgbSignature
       Receives a pointer to the signature data on successful completion.

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

       TSS_E_INVALID_HANDLE
	      hKey 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_HASH_INVALID_LENGTH
	      Hash length is inconsistent with hash algorithm.

       TSS_E_HASH_NO_DATA
	      Hash object has no internal hash value.

       TSS_E_HASH_NO_IDENTIFIER
	      The hash algorithm identifier is not set.

CONFORMING TO
       Tspi_Hash_Sign conforms to the Trusted Computing Group Software Specification version  1.1
       Golden
