Guide to Creating CSR for Code Signing Certificate

Are you a programmer or firm that develops desktop, web and mobile software or applications?

If so, you may have planned to publish it online so that users can download and install it on their devices. But today, users only install and use software with proper security measures. This can be easily handled by integrating code signing certificates into your software products.

A code signing certificate is a digital security certificate that assures users of the authenticity of the publisher. This guarantees that the software comes from verified publishers and does not contain any malicious code. In addition, these certificates are necessary to prove that your code has not been modified or changed since it was signed.

It has become important for digital brands to buy it from a trusted certificate authority or their trusted distributors like Comodo or Sectigo. But what’s next after purchasing the certificate? Next step is to create CSR for Code Signing Certificate.

Let us understand what is CSR and how it is created.

What is CSR?

The encoded text in the CSR contains information about the code signing certificate requester. This information may include the publisher’s name, contact information, and other required data. When you create a CSR, it will generate two files: the CSR, which will be requested during enrollment, and the private key, which is required during installation and should not be shared.

What is the next step after purchasing a Code Signing Certificate?

After obtaining a code signing certificate from a reputable CA or a trusted distributor, you may next want to generate a Certificate Signing Request (CSR). The CSR certificate is an encoded text created by the requester and contains all the necessary information regarding the request. This may include:

  • The generic name or name of the requester or publisher for the certificate.
  • Contact information such as email address to be contacted regarding the certificate.
  • The public key is linked to the private key of your certificate.

Once you have provided this information while generating the CSR, it will be sent to your respective CA for issuing a Code Signing Certificate. For example, let’s say you purchased a code signing certificate from a Comodo or Sectigo CA. Now, you can generate a CSR, and while doing so, you will provide the above information to that respective CA.

When you create a CSR request, it will state that your organization has requested a code signing certificate. Let us now understand how to generate CSR for code signing.
