Unable to dual sign drivers using Windows SDK 8.1 signtool RRS feed

  • Question

  • Hi,

    I am using Windows SDK 8.1 signtool to sign my drivers with two certificates :-

    1. Verisign Certificate - which uses sha1 algorithm

    2. Symantec Certificate - which uses sha256

    The problem that i am facing is that although the signtool successfully signs my driver but when i am running my application it says that the driver is not properly signed.

    I've verified the signed driver and it contains both the certificates as mentioned above.

    Any help would be deeply appreciated.
