In the digital world, ensuring the integrity and authenticity of software is crucial. This is where code signing comes into play.
Code signing is a process that uses a digital signature to verify that software or a piece of code has not been altered or corrupted since it was signed by the author. This helps users trust that the software they are downloading and installing is legitimate and safe to use.
code signing is like a digital seal of approval for software. When a developer finishes making a program, they add a special signature to it. This signature proves that the software is genuine and hasn’t been tampered with. When you download and install the software, your computer checks this signature to ensure the program is safe and trustworthy.
How does code signing work?
Code signing works by using a digital certificate issued by a trusted certificate authority (CA). The developer signs the code with their private key, and users can verify this signature using the developer’s public key, ensuring the code’s authenticity and integrity.
