Code Signing Certificate Compatibility

DigiCert Code Signing Certificates can be used to sign any type of code that requires a code signing certificate including Microsoft Authenticode, Microsoft Office VBA, Java, Adobe AIR, Apple's Mac OS, and Mozilla objects. While any modern system will automatically trust DigiCert certificates, there are a few exceptions listed below.

If your platform is not listed, there is still a good chance it is supported. Please don't hesitate to contact us if you have a question about compatibility.
