CertAlgIdToOID (Compact 2013)
3/28/2014
This function converts a CryptoAPI algorithm identifier (ALG_ID) to an ASN.1 object identifier string.
Syntax
LPCSTR WINAPI CertAlgIdToOID(
DWORD dwAlgId
);
Parameters
- dwAlgId
[in] Specifies the value to be converted to an object identifier (OID).
Return Value
Returns the NULL-terminated OID string or NULL if there is no OID string that corresponds to the algorithm identifier.
Example Code
Important
For readability, the following code example does not contain security checking or error handling. Do not use the following code in a production environment.
// 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");
}
