How to Find SSL Certificate on Server

Have you ever wondered how websites are able to securely transmit data between servers and users? The answer lies in SSL certificates. SSL (Secure Sockets Layer) certificates are one of the most important tools for establishing secure connections online.

In this comprehensive guide, we will walk you through everything you need to know about finding SSL certificates on your server.

What is an SSL Certificate?

An SSL certificate is a digital certificate that authenticates the identity of a website and enables the encryption of data transmitted over the internet. SSL certificates utilize public key cryptography to establish secure HTTPS connections between a web server and a browser.

The key benefits of using an SSL certificate include:

  • Encryption of sensitive data during transmission
  • Authentication of website identity
  • Building trust and credibility with users

SSL certificates are issued by certificate authorities (CAs) like Comodo, DigiCert, GoDaddy, etc. after validating the website’s identity.

There are three common types of SSL certificates:

  • Domain Validation (DV) – Validates domain ownership only
  • Organization Validation (OV) – Validates domain and business organization
  • Extended Validation (EV) – Highest level of validation for domains and organizations

Why Do You Need to Find SSL Certificates?

There are a few important reasons why you may need to find and view SSL certificates installed on your server:

To verify certificate details – You can validate that the correct SSL certificate is installed for your site by viewing the certificate details like domain name, validity dates, issuer, etc.

To check expiration dates – SSL certificates are only valid for a limited time, usually 1-2 years. You need to find certificates nearing expiration so you can renew them on time.

For troubleshooting issues – If your website is showing SSL errors or warnings, you may need to find the problematic certificate causing them.

When migrating servers – When moving to a new server, you need to find and transfer over existing SSL certificates to avoid downtime.

Where are SSL Certificates Stored?

SSL certificates are stored in the certificate store of your Windows server. There are different types of certificate stores where your SSL certificates may be located:

  • Personal – Stores certificates associated with private keys
  • Intermediate CA – Stores SSL certificates of intermediate CAs
  • Trusted Root CA – Stores root SSL certificates

You need to methodically check each relevant certificate store to find your SSL certificates.

How to Find SSL Certificates on Windows Server

Follow these steps to find SSL certificates on your Windows server:

1. Open Microsoft Management Console (MMC)

The first step is to open the Microsoft Management Console (MMC). This is where you can view all certificates on your server.

Go to Start and type “mmc” to open it.

2. Add Certificates Snap-in

  • In the MMC menu, click on File > Add/Remove Snap-in.
  • In the Available Snap-ins dialog, select Certificates and click Add.
  • Choose Computer account and click Next.
  • Select Local computer and click Finish.

3. Open Relevant Certificate Store

  • In the left pane, navigate to Certificates (Local Computer) > Personal.
  • If not found here, check in Trusted Root Certification Authorities and Intermediate Certification Authorities.

4. Identify SSL Certificate

  • Double click on certificates in the personal store one by one to open them.
  • Check the certificate details to identify SSL certificates for your website.
  • Match domain name, issuer details, validity dates, etc. to verify.

This will help you find all SSL certificates installed on your Windows server through MMC console.

Using PowerShell to Find SSL Certificates

You can also use PowerShell commands to find and view SSL certificates on your Windows server.

Here are the key PowerShell commands for finding SSL certificates:

  • Get-ChildItem -Path Cert:\LocalMachine\My – Lists all personal certificates
  • Get-ChildItem -Path Cert:\LocalMachine\CA – Lists trusted intermediate and root certificates
  • Get-ChildItem -Path Cert:\LocalMachine\Root – Lists trusted root certificates

Once you have listed the certificates, you can pipeline them to the Format-List command to view details:

Get-ChildItem -Path Cert:\LocalMachine\My | Format-List

This displays all the certificate properties to identify the correct SSL cert.

Using OpenSSL to View SSL Certificate Details

OpenSSL is a useful command-line tool that can help you view and verify SSL certificate details on Windows, Linux and Mac systems.

Here are the steps to view SSL certificate details using OpenSSL:

1. Open Command Prompt

On Windows, open the Command Prompt.

On Linux/Mac, open the Terminal.

2. Enter OpenSSL Command

openssl x509 -in [CERT-FILENAME] -text -noout

  • Replace [CERT-FILENAME] with the path to your SSL certificate file.
  • This will dump the complete certificate details in a readable text format. 
  • You can verify the domain name, issuers, signature algorithm, validity dates and more.

3. Review Details

Go through the certificate details dumped on your terminal to identify and validate your SSL certificate.

Locating SSL Certificates Across Your Network

If you operate multiple servers, finding SSL certificates manually on each server can be tedious. A better approach is to use automated tools to discover and map SSL certificates deployed across your entire network.

Here are some ways to locate SSL certificates on all your servers:

SIEM tools – Solutions like Splunk can monitor network traffic and index SSL certificate details.

SSL scanning tools – Software like Venafi continuously scans networks to find SSL certificates in use.

Certificate transparency logs – Public CT logs record all SSL certificates issued by public CAs which you can leverage.

Network traffic analysis – Capture and inspect network traffic to extract SSL certificate details.

Centralized visibility into all SSL certificates in your environment is critical for managing them effectively.


SSL certificates play a vital role in securing communications for your website and customers. Finding and verifying the correct SSL certificates on your server should be part of your regular security monitoring process.

This guide has provided you various methods to accurately locate SSL certificates on your Windows servers, Linux/Unix systems and across the network.

Be proactive in finding and renewing SSL certificates before they expire to minimize disruptions for your online business. Use the right tools to maintain a comprehensive inventory of SSL certificates deployed on your infrastructure.
