Overview

Restricting ECom plug-in usage to known clients

Description

To restrict the use of a DLL or ECom plug-in only to known/trusted clients, it is possible to identify the caller with RProcess::SecureID() and/or RProcess::VendorID().

Solution

Instantiating an RProcess object creates a handle to the current process (client that loaded the DLL), with its SecureID and VendorID values set.
    RProcess loaderProcess;
    if( loaderProcess.VendorID() != KMyVendorId )
        {
        return KErrPermissionDenied;
        }
    RProcess loaderProcess;
    if( loaderProcess.SecureID() != KMySecureId )
        {
        return KErrPermissionDenied;
        }
