Extended Validation (EV) certificates come along with the standard features of a digital codesign. Along with the traditional process for simple signed code, Extended Validation included a very strict vetting procedure and the requirements are extremely high for hardware security. This makes the license much more credible in comparison to typical signed code. Apart from that it also adds a layer of trust to the users and adds to the integrity of applications.
Similar to most certificates, the most essential aspect of any code signing certificate is the private key of the certificate. The private key allows the digital signature to be credibly verified by the internet browser. With the compromise of the private key, a plethora of new risks open up. They are really dangerous for the functional integrity of the software. EV Software makes sure that software is protected from the aforementioned risk by placing the private key on an external hardware token, ensuring that unauthorized access is not possible.
The purpose of the use of code signing certificates is to serve as evidence on the credibility of the product. It is also proof that the software has not been altered for any reason. This brings an extra level of confidence for users and improves the reception of the product.
