SSL Checker Tool Online: A Comprehensive Guide to Checking Your SSL Certificates

In the digital age, ensuring the security of your website is of utmost importance. One of the most effective ways to do so is by using an SSL (Secure Sockets Layer) certificate. SSL certificates encrypt the data exchanged between a user's browser and your website, ensuring that sensitive information like passwords, personal details, and credit card numbers are kept secure. To check the status and details of your SSL certificate, the SSL Checker Tool Online from CaTeL is a powerful and easy-to-use solution.

What is SSL?

SSL (Secure Sockets Layer) is a cryptographic protocol designed to provide secure communication over a computer network, primarily the internet. When a website is equipped with an SSL certificate, the data sent between the website and its users is encrypted, preventing malicious third parties from intercepting sensitive information.

SSL certificates are essential for any website that handles sensitive data, especially e-commerce sites or platforms requiring user login. SSL certificates not only secure data but also build trust with visitors by displaying a "padlock" symbol next to the website URL, which is a clear indicator of security.

How to Use the SSL Checker Tool Online

The SSL Checker Tool Online available at CaTeL is designed to make checking the health of your SSL certificates quick and easy. Here’s a step-by-step guide on how to use the tool effectively:

Step 1: Enter Domain Name

To start, simply navigate to the SSL Checker Tool page at https://catalog.tel/ssl-checker. Once you are on the page, you will see a search box where you need to enter the domain name of the website you want to check. This could be your own website or any website that you wish to inspect for its SSL certificate status.

For example, you can enter "www.example.com" or any other domain that you want to analyze.

Step 2: Press 'Examine SSL' Button

Once you have entered the domain name, simply press the ‘Examine SSL’ button. The tool will begin analyzing the SSL certificate of the given domain in real-time. It will scan the entire SSL certificate chain to ensure that the certificate is valid, properly configured, and up to date.

Step 3: Review the Results

After pressing the "Examine SSL" button, the tool will provide you with detailed information about the SSL certificate of the specified domain. Here are the key details you can expect:

Result: SSL Certificate Details

1. Given URL

The SSL Checker Tool will display the URL of the domain you entered. This allows you to verify that the certificate being checked corresponds to the correct website.

2. SSL Certificate

This section will provide an overview of the SSL certificate, including important details like the certificate type, such as SSL or TLS, and whether the certificate is active or expired.

3. Issuer

The issuer is the Certificate Authority (CA) that issued the SSL certificate. The tool will list the name of the issuing CA, ensuring that the certificate is trusted by browsers and users.

4. Expires At

Here, you will see the expiration date of the SSL certificate. This is a crucial piece of information, as SSL certificates need to be renewed periodically to maintain a secure connection. The tool will notify you if the certificate is close to expiring or has already expired, allowing you to take action before it impacts your website’s security.

5. Server Details

The SSL Checker Tool also provides information about the server hosting the website's SSL certificate. This includes several vital attributes:

• Common Name: The Common Name (CN) refers to the domain name for which the SSL certificate has been issued. This should match the domain name you entered in the tool.
• Valid: This indicates whether the certificate is currently valid. If the certificate is invalid, you will be notified, and the tool will offer insights into why it's not functioning correctly.
• SANs (Subject Alternative Names): The tool also lists the SANs associated with the SSL certificate. These are additional domain names or IP addresses that are secured by the same SSL certificate. This is especially useful for multi-domain or wildcard SSL certificates.
• Signature Algorithm: This shows the cryptographic algorithm used to sign the SSL certificate. Common algorithms include SHA-256 and SHA-1.
• Issuer: The name of the issuing Certificate Authority (CA) is displayed here as well. This helps confirm that the certificate comes from a trusted source.
• Certificate: Finally, the tool shows the SSL certificate itself, including its public key and additional metadata. This helps ensure that the certificate has been correctly installed and configured.
