We know that software development and cybersecurity require code signing certificates to ensure digital code’s authenticity and integrity. However, the effectiveness of these certificates hinges on their correct installation.
Confirming that your code signing certificate is installed correctly is not just a routine task – it’s a critical step towards building trust and security in your software applications.
This guide will verify your code signing certificate installation, demystifying the process across different platforms and browsers. Whether you’re a seasoned developer or just stepping into code signing, understanding this fundamental verification process is essential for safeguarding your code and ensuring its legitimacy in the digital landscape.
Let’s begin with the steps to validate your code signing certificate installation.
When it comes to ensuring the proper installation of your code signing certificate on a Windows system, the following steps can be taken to verify its presence:
Open Internet Explorer and proceed to the “Internet Options” menu.
Within the “Internet Options” window, locate the “Content” tab and click on it. This tab provides access to various security-related settings.
In the “Certificates” section, you’ll find several tabs. Click on the “Personal” tab to continue.
A list of certificates will be displayed in the “Personal” tab. Locate and double-click on the code signing certificate that you recently installed.
If you possess multiple code signing certificates, use the expiration date as a distinguishing factor. This will help you identify the correct certificate.
Once you access the window for the selected Code Signing Certificate, proceed to the “General” tab.
Within the “General” tab, locate the section labeled “Valid from.” Here, it should explicitly state the following crucial information:
> “You have a private key that corresponds to this certificate.”
This confirmation assures that the private key associated with your certificate is successfully installed.
If the certificate window does not contain the statement regarding the private essential correspondence, it signifies a potential issue. In such cases, initiating the re-keying process for your certificate within your account is necessary. Once this is completed, reinstall the certificate while following the installation steps.
This verification process confirms the presence of a corresponding private key. You can confidently proceed with using your code signing certificate to sign the code. This ensures the authenticity and security of your signed code projects.
To verify the successful installation of your code signing certificate within the Google Chrome browser, follow these steps:
Open Google Chrome and navigate to the “Settings” menu. You can do this by clicking on the three vertical dots in the top-right corner of the browser window.
On the “Settings” page, scroll down until you find the “Advanced” section. Click on “Show advanced settings” to reveal additional options.
Within the “Advanced” settings, look for the “HTTPS/SSL” subsection and click on “Manage Certificates.” This action will lead you to the certificate management interface.
Within the “Certificates” window, locate and click on the “Personal” tab. This tab provides access to certificates related to personal security functions, including code signing.
Find the code signing certificate you recently installed and double-click action on it. This will open up the details of the certificate.
If you possess multiple code signing certificates, utilize the expiration date as a distinguishing factor to identify the correct certificate for inspection.
Inside the certificate details window, navigate to the “General” tab. Below the “Valid from” section, there should be a statement similar to the following:
> “You have a private key that corresponds to this certificate.”
This statement confirms the successful correspondence of the private key associated with your certificate.
Should you encounter a situation where the certificate details do not include the private critical correspondence statement, it signifies a potential issue. In such cases, re-keying your certificate within your account is necessary. After this, proceed to reinstall the certificate using the installation process.
Once you’ve successfully verified the presence of the corresponding private key, you can confidently employ your code signing certificate to sign the code. This essential step guarantees the security and authenticity of your code signing activities.
To ensure that your code signing certificate is installed correctly in the Firefox browser, follow these steps:
Open Mozilla Firefox and click on the three horizontal lines in the top-right corner to access the “Options” menu.

Inside the “Advanced” settings, locate and click on the “Certificates” tab. This tab provides access to various security-related options, including certificates.
In the “Certificates” section, click the “View Certificates” button. This will open the Certificate Manager window.
Switch to the “Your Certificates” tab in the Certificate Manager window. Here, you should be able to spot the code signing certificate that you recently installed.
If you possess multiple code signing certificates, use the expiration date as a reference to identify the correct certificate. To view the detailed information of a specific certificate, select it and then click on the “View” button.
Once you’ve located the certificate you’re verifying, ensure it corresponds to the one you installed.
After confirming that your certificate is installed, you can confidently utilize it for signing code. This certificate will authenticate and secure your code signing activities.
You can verify the installation of your code signing certificate in Firefox. This validation step is crucial to guarantee the authenticity and security of your digital certificates.
If you’ve employed Safari or Chrome to install your Code Signing Certificate, follow these steps to ensure its successful installation and use:
Your Code Signing Certificate should be in the login keychain for certificates installed using Safari or Chrome.
To begin, open the “Keychain Access” application. You can do this through Finder by clicking “Applications,” then “Utilities,” and finally double-clicking “Keychain Access.”
In the “Keychain Access” window, locate the “Keychains” section. Click on “login” under Keychains to access your login keychain.

Look for your Code Signing Certificate in the list. It should appear here if you successfully installed the certificate in your keychain using Safari or Chrome.
To ensure accuracy, expand your code signing certificate by clicking on it. You should see a private key associated with the certificate.
It’s crucial to note that your certificate must have a private key corresponding to it. This private key is essential for secure code signing.
If your certificate lacks a corresponding private key, you must initiate a re-keying process for the certificate within your account. Following this, go through the installation process once more to ensure the presence of the private key.
Once you’ve verified that your certificate is installed correctly and has a corresponding private key, you can confidently use it to sign the code. This certificate plays a pivotal role in ensuring the authenticity and security of your code signing endeavors.
With these steps within the Keychain Access application, you can verify your Code Signing Certificate’s installation and readiness for code signing activities in Safari and Chrome.
If you encounter the “This certificate was signed by an unknown authority” warning message, follow these steps to resolve the issue:
Begin by opening your code signing certificate, typically by double-clicking on it.
Right-click on your certificate to reveal a list of options. From this list, choose “Get Info.”
