Buy or Renew Code Signing Certificate
Add a digital signature to your executables and remove security warnings with a Comodo Code Signing Certificate. When end users download your software, they can be confident your code is secure and has not been tampered with since it was signed.
Code signing certificates and their private keys must be stored on a FIPS-compliant hardware security module or token to protect your digital signature. Want to start signing code quickly? Comodo CA can ship your certificate to you on a FIPS-compliant USB eToken – so you can plug it into your computer and start signing files.
Industry standards from the CA/B Forum now require that all code signing certificate keys be stored on a compliant hardware security module (HSM) or hardware token. As part of implementing these changes, Comodo CA has increased code signing certificate prices. (As always, we're helping you save money by offering a discount off retail prices.) If you have any questions about the new code signing requirements, our support team is happy to help!

Comodo Code Signing Certificate Features & Benefits
Boost Customer Confidence
Customers trust software that displays a verified publisher name instead of an “Unknown Publisher” warning. Signed code helps protect end users from malicious code and assures them the code hasn’t been tampered with in transit.
Prove Software Authenticity
When signing software, you’re proving to end users that it is authentic software published by the real you, not an imposter. To get a Comodo Code Signing certificate, the CA must first verify that you are who you say you are. The verification process validates the publisher’s identity, building another layer of trust for the end user.
Seamless Integration and Ease-of-Use
Modern operating systems (e.g., Microsoft Windows) alert users that software may not be secure if it wasn’t signed via a trusted Certificate Authority. Comodo Code Signing Certificates work alongside the tools most developers already use, enabling smooth integration.
Exceed Industry Standards
All Comodo Code Signing Certificates meet and exceed CA/B Forum and NIST standards and are trusted by popular platforms such as Microsoft Windows. The Comodo Code Signing Certificate uses a 3072-bit public-key and hashing algorithm to generate a secure digital signature.
Secure Private Key Storage
Securely store your private key and certificate in a USB token or hardware security module (HSM). Secure storage ensures your private key and certificate can’t be easily lost or stolen by malicious actors.
Remove Security Warnings
Ensure end users can install and download your software without receiving the Microsoft Windows “Unknown Publisher” warning.
Comodo Code Signing Certificates are compatible with a wide range of major file types – Mozilla Objects, Microsoft VBA, Adobe AIR, Microsoft Authenticode, Java, and MS Office Macros. You can digitally sign both 32-bit and 64-bit executable files such as .exe, .dll, .csx, .cab, and more.

What is Code Signing?
When customers buy software in a store, its shrink-wrapped and sealed to ensure it hasn’t been tampered with – but what about when they purchase software online?
Code signing certificates serve as a virtual “shrink-wrap” for your software: once you sign your software, the digital signature will break and warn customers the code isn’t trustworthy if it’s tampered with in any way. That way, when customers download digitally signed files (including .exe, .cab, .jar, and more) or drivers from your website, they can be confident your code really comes from you and hasn’t been corrupted since it was signed.
Assure the software hasn’t been tampered with since it was signed.
Authenticate the software’s origin from a verified individual or legally registered business.
When Do You Need to Sign Code?
You’ll need to sign your code to distribute the software—whether over the internet, through distributors, or via another medium. When the code is signed, it tells users and customers it hasn’t been altered or tampered with by unknown sources. In addition, signed code helps distinguish legitimate software or code from your organization from fraudulent code from an impersonator.
Aside from verifying the software’s origin and establishing trust with the end user, code signing is essential if you want people to download and install your software or code. People are innately wary of digital downloads and won’t want to download software marked as “unverified” or a potential “security risk.”
