To ensure secure and reliable signing practices in your automated build environments, consider the following best practices.
- 
                     Avoid storing PFX files directly on build agents; use AWS CloudHSM or KMS for secure key management. 
- 
                     Use timestamping for long-term signature validity. 
- 
                     Implement role-based access control via IAM. 
- 
                     Consider signing in isolated environments (e.g., CodeBuild or EC2 with least privilege). 
The table below outlines common problems, their causes, and recommended solutions.
| Issue | Possible Cause | Suggested Action | 
|---|---|---|
| "No certificate found" | Incorrect PFX path or missing permissions | Check certificate path and access rights | 
| "Provider cannot be found" | Middleware not installed or misconfigured | Ensure KSP or CNG bridge to AWS is correctly set up | 
| "Signature invalid after 3 days" | Missing timestamp | Add /tr and /td flags to the command |
