Ask HN: Can hash verification replace EV code-signing on Windows?

1 point

3 months ago

I ship an offline Windows tool and instead of paying for an EV certificate, I am experimenting with a detached verification model:

1. User downloads the .exe from GitHub Releases 2. User downloads verify.ps1 (60-line PowerShell script, zero dependencies) 3. User runs: .\verify.ps1 .\MyApp-Setup.exe

The verifier computes SHA-256 and checks against a hardcoded manifest. No network calls. No certificate chain.

The thesis: for technical users, this is higher trust than opaque SmartScreen telemetry.

Open questions: - Does the verification step give users enough confidence to click through SmartScreen? - Is there prior art for this in the Nix/Guix ecosystem? - What is the minimum viable UX for hash verification?
