NAME
       Tspi_Hash_VerifySignature  -  verify the hash value with a given signa-
       ture

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_VerifySignature(TSS_HHASH hHash,             TSS_HKEY hKey,
                                            UINT32    ulSignatureLength, BYTE*    rgbSignature);



DESCRIPTION
       Tspi_Hash_VerifySignature verifies the hash value of a given  hash  ob-
       ject  with  a  given  signature. In order to use this command, one must
       have a hash and a signature of the hash that one is trying  to  verify.
       The  public  key  which corresponds to the private key used to sign the
       hash is also needed.


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 verifi-
       cation.

   ulSignatureLength
       The length of the signature data provided at  the  parameter  rgbSigna-
       ture.

   rgbSignature
       A pointer to the signature data.


RETURN CODES
       Tspi_Hash_VerifySignature 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_INVALID_SIGSCHEME
              Invalid signature scheme.



CONFORMING TO
       Tspi_Hash_VerifySignature conforms to the Trusted Computing Group Soft-
       ware Specification version 1.1 Golden
