Episode notes
Code Signing Rules Became Burdensome
- Code signing rules now force non-exportable keys and HSM or cloud-hosted signing, increasing complexity and cost for developers.
- Rick Strahl and Steve Gibson see this as gatekeeping that burdens small developers and raises yearly costs dramatically.
Evaluate Azure Trusted Signing Costs
- Consider Microsoft's Azure Trusted Signing for cheaper, cloud-based code signing despite setup pain and preview status.
- Weigh signature quotas and monthly pricing (basic vs premium) before choosing cloud signing plans.
Three-Day Certificates Purpose
- Microsoft issues very short-lived code signing certificates (about three days) to thwart abuse if keys are compromised.
- Short lifetimes reduce window of misuse while relying on timestamping to preserve signature validity.
