How to Collect Comodo EV Code Signing Certificate?

It is a brave new world with millions of users downloading and installing mobile applications each day. But unfortunately, these apps can be a cybersecurity nightmare without an Comodo EV code signing certificate.

Take an example of Capital One. The US banking giant used hosted AWS system to power its customer-facing applications. In 2019, they faced the server-side request forgery(SSRF) attack. It compromised millions of user data.

You can avoid such attacks by using an EV code signing certificate from a trustworthy certificate authority like Comodo. EV stands for extended validation, where a CA vets the requestor organization’s identity, location, business legitimacy, etc.

Further after the vetting process, a code signing certificate is issued for an application. It allows users to authenticate the identity of the publisher before downloading it. Here is a guide for collecting your Comodo EV Code Signing Certificate for enhanced security.

Let us begin with a basic understanding of the EV code signing certificate.

EV Code Signing Certificates: An Overview

An EV code signing certificate is perfect for enterprises looking to secure experience for their customer-facing apps. It offers enhanced security and a higher level of authentication. Increased trust in applications means higher downloads.

An EV code signing certificate has extended validation that involves a two-factor authentication of the publisher’s identity. The code signing needs private keys stored on physical storage. So, it provides an extended vetting of the software or app publisher before issuing the certificate.

Most of the CAs like Comodo provides EV code signing certificate with support for Windows SmartScreen. Microsoft Defender SmartScreen or Windows SmartScreen protects the Edge browser from phishing websites and filters malicious websites.

So, if there is no support for the Windows SmartScreen, your users will face warning. This is where a Comodo EV code signing certificate can help. Now that we have an idea about the EV code signed certificates let us understand how to collect one for your organization.

Here is what you get in the package,

  • Hardware security module-based card- You will get a card with a chip that has a private key stored in it. The device or card is as per the HSM standards.
  • Reader for the HSM card-It is a device that reads the HSM card and locks your apps with the private key.
  • An acknowledgment letter is a letter from the certificate authority with all the necessary instructions and acknowledgment of the code-signed app.

Now that you know what is to expect from the EV code signing package let us understand the steps to collect it.

Steps to Collect Your EV Code Signing Certificate

One of the critical aspects of your acknowledgment letter will lead you to the first step of collecting the Comodo EV Code Signing Certificate. So, it is recommended not to throw it away or misplace the letter.

For you, what matters is the software without which you may not be able to access the certificate. First, go to the URL provided in the acknowledgment letter and download the executable file. After downloading the software, install it and restart your computer.

Step 2 Plug in your Smart Card
