Signing windows executable/dll



  • Hello,
    I have some questions about signing executables/dll in qt for WIndow 7, 8, 10. Our software will be downloaded from our website and installed by end users.

    1. What are the reasons to sign executable/dll?

    2. How to sign qt executable/dll?

    3. Where to get cetificate/tools needed to sign? Is it possible to obtain that for free?

    4. Should I sign every single dll which comes with our software? Are dlls loaded by Windows application checked for signature and if it is not correct Windows refuses to load the dll?

    1. To trust (be sure that your app is not modified by viruses and so on).
    2. Read MSDN.
    3. Buy it from verisign.
    4. Yes, need to sign all binaries.
