How to Choose a Code Signing Certificate

If you are a software developer, you know how important it is to code sign your applications. This helps ensure that users can trust the software they download and install on their devices. You will need to obtain a code signing certificate to code sign your applications. But how do you choose the right certificate? How do you get practical code signing guidance? This blog post will discuss the different types of certificates available and help you decide which one is right for you!

Why Do We Need Code Signing Certificates?

Code signing certificates are used to sign applications and software digitally. This helps ensure that the software is authentic and has not been tampered with. When a user downloads an application that has been code signed, they will see a message like this:

This message lets users know that the software was created by a trusted source and has not been modified in any way. It also provides them with some peace of mind knowing that the software is safe to install on their device.

How To Choose The Right Code Signing Certificate

When it comes time to choose a code signing certificate, there are several factors you need to consider. First, you need to decide which type of certificate is right for you. There are three types of certificates available: single domain, multiple domain, and wildcard.

Single Domain Certificates are used to sign software for a single domain name. For example, if you want to code sign an application installed on devices with the .com extension, you would need a single domain certificate.

Multiple Domain Certificates are used to sign software for multiple domain names. For example, if you want to code sign an application installed on devices with the .com and .net extensions, you would need a multiple domain certificate.

Wildcard Certificates allow you to sign software for an unlimited number of subdomains. For example, you would need a wildcard certificate if you have a website with the following domains: companyname.com, companyname.net, and companyname.org.

Once you have decided on the type of certificate you need, you will need to decide which certification authority (CA) is right for you. There are several CAs available, each with its own set of features and benefits. Do your research and decide which CA offers the best deal for your needs.

How To Get Started With Code Signing Certificates

The first step in getting started with code signing certificates is to decide which type of certificate is right for you. Once you have selected the appropriate certificate, you must purchase it from a CA. Next, you will need to create a code signing key pair.

You can find more information on how to do this in the documentation for your development environment.
