How do Code Signing Certificates work?

Any given certificate binds a user's identity to a public key, which can then mathematically be associated with a specific private key. This is the basis for Public Key Infrastructure (PKI): in this case, the verified user signs code using their private key. Anybody who attempts to download signed code afterward will use the identity-affirming public key to check for potential tampering.

Therefore, Code Signing SSL certificates protect all involved parties by providing a special digital signature that can verify their identities and issue an assurance or a warning, depending on whether something is amiss. This principle is applied by certificates code signing software that is available for download from the Internet. All thanks to PKI.

Where does Signed Code Security come into play?

Applicable downloads can be comprised of drivers, system updates, 32-bit OS applications, or a simple file collection, just to name a few. If there's no certificate in place to digitally sign said downloads, then the user gets a security warning when opening the downloaded software.

When a CA applies a digital signature to code attached to your identity (i.e. published on your protected website), it records a special timestamp. This timestamp signifies that the certificate used could confirm the code's validity at that moment in time. Whenever someone makes a change to the code to, say, improve hardware support, add management features, or introduce extra security solutions, the signature needs to be re-applied.

Why are Code Signing Certificates so Important?

Signing code is absolutely crucial when it comes to company trustworthiness. Both in the private and business spheres, depending on your code's purpose. Security is key if you want your website and/or service to persevere online, and any extra level of authenticity and trustworthiness you can add to your products is a must-have.

Since modern web security solutions rely so heavily on PKI, ensuring the source and integrity of downloaded content requires no outside support, once a certificate is in place. Maximum security with a minimum of management needed.
