[TrouSerS-users] Fwd: Binding problems

[Giovanni F. <gio...@gm...>]

I'd like to make a precisation
Using Tspi_data_seal instead Tspi_dataBind (adding a NULL pcr value
and specifing that the encrypted object will be TSS_ENCDATA_SEAL
instead TSS_ENCDATA_BIND)
everithing work fine

Goodmorning,
i'm writing some test cases using the TPM and now i would like to
perform a binding operation. My problem is that when i call the
binding functioni obtain an error and the returned value isn't one of
the returned possible values.
This is the interesting part of the code:

/* Bind the symmetric key */
       result=Tspi_Data_Bind
           (hEncdata, hKey, EVP_CIPHER_key_length(EVP_aes_256_cbc()),
            randKey);
       if (result !=TSS_SUCCESS) printf("\n Error encrypting the symmetric
key %d\n",result);
       if(result==TSS_E_INVALID_HANDLE) printf("\n TSS_E_INVALID_HANDLE \n");
       else if(result==TSS_E_BAD_PARAMETER) printf("\n TSS_E_BAD_PARAMETER \n");
       else if(result==TSS_E_INVALID_ENCSCHEME) printf("\n
TSS_E_INVALID_ENCSCHEME \n");
       else if(result==TSS_E_ENC_INVALID_LENGTH) printf("\n
TSS_E_ENC_INVALID_LENGTH \n");
       else if(result==TSS_E_ENC_NO_DATA) printf("\n TSS_E_ENC_NO_DATA \n");
       else if(result==TSS_E_ENC_INVALID_TYPE) printf("\n
TSS_E_ENC_INVALID_TYPE \n");
       else if(result==TSS_E_INTERNAL_ERROR) printf("\n
TSS_E_INTERNAL_ERROR \n");
       else
       printf("\Unknown Error\n");


The list of IF - ELSE IF has only be added to understand the error
returned, but i obtain always unknown error.
How is it possible ?

PS. The "result" variable as been declared as TSS_RESULT result;
