string certPath = @"Test.pfx";
string certPass = "demo123";

Byte[] contentBytes = File.ReadAllBytes(certPath);

//boxing to the object
object comObject = contentBytes;

bool privatKey = SigDev.OverrideKey(0, comObject, certPass, "");
bool publicKey = SigDev.OverrideKey(1, comObject, certPass, "");
                
//  Disable Confirmdialog (Digital Signature will be added by Driver instead from the Pad)
SigDev.SetDriverLong(0, SigDev.GetDriverLong(0) | 0x00010A90);
