CertAlgIdToOID (Windows CE 5.0)
This function converts a CryptoAPI algorithm identifier (ALG_ID) to an ASN.1 object identifier string.
LPCSTR WINAPI CertAlgIdToOID(DWORDdwAlgId);
Parameters
- dwAlgId
[in] Specifies the value to be converted to an object identifier (OID).
Return Values
Returns the NULL-terminated OID string or NULL if there is no OID string that corresponds to the algorithm identifier.
Example Code
// EXAMPLE CODE USING CertAlgIdToOID() to
// convert the CALG_SHA algorithm identifier to an
// object identifier string.
+
//--------------------------------------------------------------------
// Declare variables.
LPCSTR pszObjID;
if(pszObjID= CertAlgIdToOID(CALG_SHA))
{
printf("The OID for CALG_SHA is %s \n",pszObjID);
}
else
{
printf("No object identifier string correlates to the ALG_ID. \n");
}
