Extended validation code signing certificate

I have a doubt whether EV code signing certificate can be used for one driver itself or in future, if I develop another driver, can I use old one?

A code signing certificate is issued to a COMPANY, and you use it to sign an executable (for example) to “prove” who wrote the code. As long as the certificate is valid (they DO expire) you can use that certificate as many times as you want.

Thanks for quick response Peter Viscarola. So, EV certificate is valid for one year only, after that we may need to renew or it works after one year also?

Different Certificate Authorities sell EV Certs with different validity periods.
During the Cert’s validity period you can use it to sign code. When the cert’s validity period ends, the code will still be signed (and drivers signed will still load), but you no longer use the (now expired) cert to sign additional drivers.
