Code Signing Resources & Support Guides

Every encryption strategy eventually runs into the same question: where do the keys actually live? An HSM (Hardware Security Module) is a physical device that generates and guards cryptographic keys inside a sealed, tamper-resistant boundary � the keys never leave in readable form.

Your Azure application build is complete. The installer is packaged, the pipeline has run, and it is ready for distribution. Then Windows Defender SmartScreen evaluates it � and presents the end user with an “Unknown Publisher” warning that stops the install cold. If you have been in cloud-native software delivery long enough, you know this moment. The fix is not complicated, but it must be done correctly, and in 2024 the standards for what “correctly” means changed significantly.

The Open Worldwide Application Security Project (OWASP) has been defining application security standards since 2001. Most developers know the OWASP Top 10 � a list of the most dangerous web vulnerabilities. But the OWASP Secure Coding Practices are a different animal entirely.

Every time you walk away from your computer and come back to a beautiful wallpaper with a clock on it, that’s not magic � that’s LockApp.exe doing its job quietly behind the scenes. But what exactly is it? Is it safe? And what should you do when it starts misbehaving?

Every time you visit an HTTPS website, connect to a corporate Wi-Fi network, establish a VPN tunnel, or run signed software, Windows quietly checks a digital certificate behind the scenes. These certificates are the backbone of trust in modern computing � they verify identities, encrypt communications, and authorize software. But where does Windows actually store and manage them?

Code signing is a non-negotiable requirement for distributing Windows executables. Whether you’re publishing an installer, distributing internal enterprise tools, or deploying signed binaries for CI/CD, Windows requires Authenticode signatures to establish trust and prevent tampering.

If your Windows 11 or 10 PC is behaving unpredictably � crashing, freezing, or showing strange hardware errors � unsigned drivers might be to blame. Drivers act as communication bridges between your operating system and hardware. When a driver isn�t digitally signed, it means Microsoft hasn�t verified its integrity or compatibility, which can lead to serious issues.
