Code Signing certificates attach a digital signature to code to validate that the content has not been altered since it was signed and distributed. Code signing works with software components, macros, firmware images, configuration files, and other types of content. Driver Signing certificates (also know as kernel-mode Code Signing certificates) are identical to Code Signing certificates, except they are specifically designed to secure code from Windows® hardware drivers and operating systems. Driver Signing certificates are required to sign all drivers on any Windows Vista® operating system or later.
As an independent developer or programmer, your code is your reputation. If your release is hacked, infected, or altered in any way, customers won't trust you enough to give you a second chance. Protect yourself, your customers and your good name with the rock-solid security of a code or driver signing certificate.
