IObjectId interface (certenroll.h)

  • Article

The IObjectId interface represents an object identifier (OID). OIDs are returned from numerous Certificate Enrollment API properties, and they can be used to initialize the following objects:

All of the methods used to initialize an IObjectId object call the CryptoAPI CryptFindOIDInfo function which retrieves the first registered CRYPT_OID_INFO structure that matches the specified parameters. The function searches the registry and static memory on the local computer and Active Directory on the domain server. The CRYPT_OID_INFO structure is declared in Wincrypt.h and has the following signature.

Note  You cannot use the CRYPT_OID_INFO structure directly in the Certificate Enrollment API.

 

Inheritance

The IObjectId interface inherits from the IDispatch interface. IObjectId also has these types of members:
