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 particular 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 which verifies their identities and issues 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, for example. 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.

Very happy with the service from SSLTrust! I had to organise a code signing certificate with a hardware token. Having somewhere local made the process much smoother for verification. Support is also very quick to answer which is a great change!

SSLTrust support is first rate. They assisted me with each issue I faced from the start of ordering a code-signing certificate through to actually receiving the certificate. I couldn't have hoped for more prompt support. I wish there were more Australian IT companies, and that have this level of care for their customers. Highly recommend to anyone needing such services.

Code Signing Certificates FAQ

You can get Code Signing SSL certificates right here at SSLTrust! Simply choose between the various Comodo and DigiCert Code-Signing certificates featured on this page, and click on the appropriate link. Setting it all up is easy as pie, once you get past choosing between the different options.

You don't technically need Code-Signing SSL certificates, but the simple truth is that they can hugely improve the trustworthiness of your software. By extension, your customers will be far more likely to trust your code, which is a huge boon for any software developer and/or publisher. They're an easy and foolproof way to ascertain your identity to all interested parties.

Any given Code Signing certificate can provide you with more or less the same level of authority. CA options available via SSLTrust will verify your identity and sign your software quickly and easily, giving both business and private customers assurance for your organization.

EV Code Signing certificates do come with improved feature sets for enterprise-grade developers. They provide more trust in your identity and can have the benefit of less error messages shown on the users computer.

Code Signing necessitates a thorough audit of the author's identity and integrity, doubly so in the case of EV Code Signing certificates. The process includes all manner of reputation lookup, so that the CA can make a reliable identity assurance when all is said and done. This is a costly process, of course.

Getting a Certificate Authority to digitally sign your code is no small feat. While the system has been significantly streamlined over the years, it still requires a lot of groundwork before a CA can verify your code. This is done to protect both you and your customers, too.

There are no free Code Signing SSL certificates for you to use to protect your software. The process of getting a certificate code signing in place takes a fair bit of effort from Certificate Authorities, and you should be suspicious of anyone offering this manner of security for free.
