Code Signing
Code signing is a security practice that uses digital signatures to verify the authenticity and integrity of software code, executables, or scripts. It involves a developer or organization signing their code with a private key, allowing users to verify that the code comes from a trusted source and hasn't been tampered with since signing. This is commonly used for applications, drivers, mobile apps, and software updates to prevent malware distribution and ensure trust.
Developers should use code signing when distributing software to end-users, especially for commercial applications, mobile apps (iOS/Android), browser extensions, or system-level software where security and trust are critical. It's essential for passing app store requirements (e.g., Apple App Store, Google Play), preventing warnings about untrusted software, and protecting users from malicious modifications. In enterprise environments, it helps enforce software policies and secure updates.
