Software Publisher Certificate Validation Levels

Whether you purchase Windows Code Signing Certificate or any other, you must select a validation level. It will define the level of security and authenticity of your software. Further, the Primary three levels include:

Individual Validation Code Signing (IV)

IV Code Signing Certificate is the only digital certificate available for independent software developers. To avail of it, you don't need to have a registered company and a high budget. It is available at a low cost, and its vetting process also gets completed within minutes.

Furthermore, it’s the lowest validation level, opening a slight probability for users to face an Unknown Publisher Warning. However, if your purchase it from a trusted provider, you can prevent system alerts.

Individual Validation Code Signing Certificates leverage with:

Optimizes your brand name’s trust across all major platforms
Improves authenticity and productivity
Protect software from unauthorized alterations

Organization Validation Code Signing (OV)

OV Code Signing Certificate is above the IV certificate, and only registered companies can utilize it. Its vetting procedure is rigorous, as Certificate Authority verifies all the details with government databases.

Whether you are a startup or a large enterprise, each one must sign their software before release. In addition, online app stores only allow applications with Code Signing Certificates to get listed on the charts.

Further, OV Code Signing Certificates leverage with:

Limitless software validity with timestamping
Elimination of Unknown Publisher Warning
Recognition as a legitimate publisher across Windows, Linux, and macOS
The unlimited signing of files of different types

Extended Validation Code Signing (EV)

EV Code Signing Certificates are for organizations requiring more solid security than OV certificates. Likewise, the OV certificate, EV is also only for firms. But, CA takes around 1 to 5 days to complete its validation procedure.

Certificate Authority strictly follows every CA/B Forum guideline during the Extended Validation process. As a result, any discrepancy leads you to start from the beginning. And once you fulfill the criteria and the CA issues the EV Code Signing Certificate, you get the benefits of it.

EV Code Signing Certificates leverage with:

Your software users don't face Windows Defender SmartScreen warnings.
CA provides a private key in a hardware token.
Every operating system treats your software as authentic.

How Software Publisher Certificate Works?

Software Publisher Certificate functions on the fundamentals of hashing and encryption. When you select the file to get signed, it hashes its content and creates a hashed file. Further, it encrypts the hashed file and integrates your signature and a timestamp. To encrypt the file, it uses the private key, and as a result, you get the signed software.

Further, when an end-user initiates the installation of signed software, the system verifies the signature, CA details, and timestamp data. If the software satisfies the system's criteria, installation begins.

Why a Software Publisher Requires a Digital Certificate?

Build confidence among users about the brand
Prevents malicious actors from altering source code
Removes Unknown Publisher Warnings

The Fundamental Roles in Code Signing Ecosystem

The Code Signing Certificate Ecosystem consists of the following stakeholders:

Certificate Authorities (CAs)

Certificate Authority is the primary entity in the ecosystem responsible for issuing Code Signing Certificates to genuine publishers. Also, the CA is responsible for validating the developer's details to decide whether to provide a digital certificate.
Software Publisher

Software Publisher is the individual or the organization providing the applications to consumers. A publisher undergoes the vetting process to avail Code Signing Certificate to tamper-proof the source code.
Software Distributor

Software Distributor is the entity through which a customer purchases the software. For instance, if you buy a Microsoft Windows OS from Amazon, then Amazon is the software distributor.
Software Consumer

Software Consumer is the end-user who installs the software on their machine and utilizes it. When a consumer installs software, the system analyses publisher’s signature and CA details.

What to Expect after using a Software Publisher Certificate?

Once you sign the software, you don’t have to fret about the Unknown Publisher Warning. Each customer will seamlessly install the application, regardless of the operating system. In addition, your software will be safe from malicious actors, as the code will be in an encrypted format.

In the image with the title Unverified Publisher, the system shows an Unknown Publisher Warning due to non-signing of the software. However, in a verified Publisher's case, the system asks the user to move further in the installation process.

Hence, your customers will experience flawless installation after you sign your software.
