EV Code Signing Vs OV Code Signing Certificate Difference Explained

Digital code signing certificates protect an application from every kind of phishing attack and modifications by external guests. Software developers use code sign certificate to sign their files, applications, and drivers, etc securely so that customer knows that your application/software is secure and cannot be tampered easily by anyone. When software developers go for a code sign certificate, they have two options to choose from: standard OV (Organization Validation) CodeSign Certificate and EV (Extended Validation) CodeSign Certificate.


What is an EV Code Sign certificate?

EV code sign certificate is just another type of code sign certificate that provides a higher level of security including more rigorous vetting of the customer who wants to buy this product. Moreover, in this type of certificate private keys are stored in a token externally to prevent them from any unauthorized hands. That’s the only big difference between standard and extended validation code sign certificate.

CA/B Forum has also set some guidelines on how all CA’s will issue these two code sign certificate types like EV code sign requires intensive verification before issuing certificate to website/software. And another one is that it cannot be issued to an individual, although the sole proprietor can apply for the same certificate. If someone already has a standard code sign certificate, they automatically get qualified for EV code signing certificate, and then we can skip few steps in the verification process.
