Sample Code Showing Bilateral Authentication in AddInAuthenticate()

Here is an example of typical code that might be added to an AddInAuthenticate function to accomplish bilateral authentication:

ISL_VERIFIED_MODULE_PTR VerifiedCLModulePtr = NULL;

ISL_STATUS islret;

void* retAddress;

ISL_CONST_DATA key = {0, NULL};

ISL_CONST_DATA signer = {0, NULL};

CSSM_PROC_ADDR tmp;

int i;

shl_t pImage = NULL; uint8 work[2][1024];

key.Data = (uint8 *)&work[0]; key.Length = 1024; signer.Data = (uint8 *)&work[1]; signer.Length = 1024;

pImage = (shl_t)pVerifiedModule->hModule; pVerifiedModule->Path.Length = 50;

tmp = NULL;

if ((i = shl_findsym( (shl_t *)&pImage, “ISL_RetrieveRootIssuerKey”,

TYPE_PROCEDURE,

(void *)&tmp ) ) != 0 )
