Trying to figure out how to install a Sectigo (Comodo) code signing certificate? This intuitive guide will help get your code signing certificate ready in just 3 easy steps

Before we dive into the Comodo code signing certificate instructions, let’s quickly clarify something. The days when you could generate a publicly trusted code signing certificate in your browser and install it on your computer or server are over. The industry upgraded its code signing baseline requirements back in 2023 to ensure that all publicly trusted code signing certificates’ private keys are generated only on secure hardware and aren’t handled directly.

Wondering how the new process of getting a code signing certificate works? Our Sectigo code signing instructions (otherwise known as Comodo code signing instructions) will walk you through the process with plenty of screenshots to help you along the way.

How to Get a Code Signing Certificate in 3 Steps

Getting a code signing certificate boils down to three key steps that we’ll cover in our Comodo code signing instructions:

  1. Purchasing a code signing certificate from a CA or authorized reseller
  2. Completing the validation process
  3. Setting up the code signing certificate’s secure hardware

Step One: Purchase a Comodo Code Signing Certificate

Browse our code signing certificate offerings for Microsoft Authenticode, Java code signing, and more. Select your code signing certificate of choice and hit the green Add to Cart button. This will bring up a new window where you can specify the number of coverage years for the certificate — i.e., up to about 3 years (or a maximum of 39 months) — and your preferred certificate delivery method.

In the top drop-down menu, select how many years you want the certificate to be good for:

NOTE: Unless otherwise specified, all code signing certificates must be generated on secure hardware (i.e., FIPS 140-2 Level 2, Common Criteria EAL 4+, or equivalent compliant as a minimum). Comodo Code Signing Certificates, issued by Sectigo (formerly Comodo CA), are delivered on a secure hardware token by default.

Already have a hardware security module (HSM) and want to install your certificate there? Select the Install on Existing HSM option in the certificate order drop-down menu (shown below) and continue with the checkout process. (Click the red More Info link to see which devices are supported.)

Step Two: Complete the Validation Process

Alright, this next part of the process varies based on the validation level of the code signing certificate you choose. For example, code signing certificates come in three validation levels, ranging from lowest to highest:

  1. Individual validation (IV) for independent developers. This process is a bit different from the other two validation methods because you’re proving your personal identity.
  2. Organizational validation (OV) for businesses seeking base business validation.
  3. Extended validation (EV) for organizations seeking the highest validation.

The validation process itself involves four key steps:

  • Proving your personal or organizational identity: This involves providing key verifying information to the issuing CA (in this case, Sectigo).
    • For individuals, this involves providing a copy of your physical ID and engaging in a face-to-face video call to verify your identity.
    • For businesses, this entails the CA using government documents and other official resources to verify your organization’s registered legal status.
  • Confirming your physical locality: For this process, the CA verifies that your organization has a physical presence in a specified locality (i.e., in a specific city and state).
  • Completing a verification phone call: The CA checks to ensure your organization has an associated active telephone number listed in an online directory that matches the one you provide.  
  • Completing a final verification phone call: This last step of the process requires a CA validation expert to call and speak with the specified applicant using the business phone number that was provided to confirm the order details. It’s a straightforward and fast phone call that won’t take much of your time.

That’s it!

Step Three: Set Up the Secure eToken or HSM

For this example, we’ll use a standard Comodo Code Signing Certificate that’s stored on a Thales SafeNet eToken.

Sectigo generates and stores the certificate and key on the secure eToken for you. This means you don’t have to mess around with provisioning a certificate and key yourself. After purchasing your Comodo Code Signing Certificate, all you have to do is sit back and wait for the eToken it’s stored on to arrive in the mail.

Once you’ve received your token, you’ll need to install the SafeNet Authentication Client onto your machine and go from there.
