问题
This problem may not be as simple as the title says, because for some reason, I am not authorized to have a certificate, and I can only give the program (not the code) to another person for digitally sign. I'll elaborate on the following.
What I already know is that after I upload the app to MS store, Ms store will automatically sign my app, but it seems that it will only sign the msixbundle file. because in this path: C:\Program Files\WindowsApps\[AppName]_[AppVersion]_neutral__[PackageID], I can see my DLL files and exe files - but these files are not signed, unless the DLL has been signed before uploading the app to the store, for example, Newtonsoft.Json.dll in the directory is signed, but my own [appname].exe file is not signed.
So, the question is: how can someone else sign my desktop bridge app installation files using signtool.exe without having my code?
Maybe this can't be achieved, but please tell me the solution, thank you.
