Troubleshooting VBA Code Signing and Digital Signatures in Office

Signing macro-enabled files is essential for security, but it can be incredibly frustrating when your digital signatures do not appear or function correctly in file properties. This comprehensive text-based course helps you demystify the code-signing process for Office files. You will transition from encountering confusing security warnings to confidently signing, validating, and troubleshooting digital certificates for Excel and Word macros. What you'll learn: - Understand the foundational concepts of cryptography, digital certificates, and local trust stores. - Apply digital signatures to macro-enabled Excel and Word documents correctly. - Diagnose why the digital signatures tab might be missing from file properties. - Configure timestamping to ensure signatures remain valid after certificate expiration. - Establish trust relationships using local policies and Trusted Publishers. The course starts with essential security terminology and certificate mechanics before exploring practical troubleshooting steps to resolve visibility and validation issues. This course is designed for beginners, developers, and system administrators who need to secure macro-enabled files without any prior cryptographic experience.
