Hardware Errors

Hardware Errors

If the hardware fails, Crypto-C will return an error of BE_HARDWARE or

BE_NOT_SUPPORTED. BE_HARDWARE indicates that the Intel primitive has returned an

error. This error can be retrieved using

B_GetExtendedErrorInfo (described in the

Crypto-C Library Reference Manual), as shown below. In this example,

randomAlgorithm

is an algorithm that has been created to retrieve a seed from the Intel Random

Number Generator. The data returned in the data field of

errorData

is a structure

of type

A_RSA_EXTENDED_ERROR (see A_RSA_EXTENDED_ERROR on page 11). The third

parameter will return a pointer to the algorithm method that was in use when the

error was encountered:

For information about the Intel error codes returned by

B_GetExtendedErrorInfo,

consult Appendix B.

An error of

BE_NOT_SUPPORTED may mean that there is a problem accessing the BHAPI

driver. See Appendix A for more information.

ITEM errorData;

POINTER am;

B_GetExtendedErrorInfo(randomAlgorithm, &errorData, &am);

/* Print out the error information. */

if (am == &HW_INTEL_RANDOM) {

printf ("[Seed] Code: %d\n",

((A_RSA_EXTENDED_ERROR *)errorData.data)->errorCode);

printf ("[Seed] Message: %s",

((A_RSA_EXTENDED_ERROR *)errorData.data)->errorMsg);

}
