SSL/TLS protocols are the unsung heroes of the internet. They:

Encrypt internet traffic

Authenticate server identity

Ensure that data transferred over the internet is secure

Verify the identity of the website being accessed

The widespread adoption of SSL/TLS as baseline web security measures is designed to protect data from interception and maintain user privacy during online interactions.

Now, let’s dive into the specifics of these protocols. HTTPS, which incorporates SSL/TLS, offers a more secure connection than HTTP by encrypting data exchanged between the user’s browser and a website. This encryption aids in the prevention of data interception and tampering, ensuring your online interactions remain private and secure.

Certificate Essentials: Decoding the Details

SSL certificates are like passports for websites; they contain important details that help identify the website. These details include:

The domain name

The entity they’re issued to, which includes the common name

The issuing certificate authority

The certificate’s validity dates

In recent years, there has been a notable shift from using the common name in SSL certificates to using the Subject Alternative Name for verifying server identity.

The Importance of Valid SSL Certificates

Validity is a key attribute of SSL certificates. They are crucial for:

Maintaining secure user data

Authenticating domain ownership

Preventing fake site creation

Ensuring secure website transactions

A valid SSL certificate contributes to building trust by verifying the authenticity of the website and protecting online interactions.

SSL certificates contain important details including:

The domain name

Certificate authority

Validity dates

Public key

For additional certificate details, please refer to the issuing authority’s documentation.

These details serve to validate the website’s identity. Initiatives like the HTTPS-Only Standard mandate secure and private online interactions, underscoring the need for valid SSL certificates on all publicly accessible federal websites.

Step-by-Step Guide to Checking Your SSL Certificate

An SSL Certificate Checker is a handy tool used to verify the proper installation and validity of a website’s SSL certificate. Simply enter your website URL or server hostname into the SSL Checker to initiate the review process.

Just like a health check-up can reveal potential health issues, the analysis from the SSL Checker will display the status of your SSL certificate, including any errors or warnings that need attention.

Inputting Your Server Hostname or Website URL

The initial step in using an SSL Certificate Checker like is similar to entering a destination into your GPS. You input the website’s URL or server hostname into the designated field of the checker tool. To check an SSL certificate, you insert the URL into the provided space and initiate the check to receive information such as:





expiration dates.

Certain rules apply, though. To check an SSL certificate using a certificate checker tool, you enter the public hostname of the server. But remember, internal hostnames are not accepted by SSL Certificate Checkers; only public hostnames should be entered.

Analyzing the Results: What to Look For

Once you’ve initiated the check, it’s crucial to know what to look for when interpreting the results. You need to verify the certificate’s expiry date to ensure it hasn’t expired and is still valid for a certain duration. Checking the certificate details to determine if all the domain names and subdomains that you want to secure are indeed listed and properly covered by the certificate is also important.

Identifying the certificate’s issuing authority and checking for any additional points or flags that may be indicators of warnings or errors within the certificate’s status is another critical factor. If the website uses an extended validation (EV) certificate, the certificate results should include clear identification of the organization to ensure the certificate is not only valid but also provides a high level of trust.

The Impact of SSL on User Trust and Google Rankings

The benefits of SSL extend beyond encryption and security. The padlock icon visible in a browser’s address bar is a common indicator that a website holds an SSL certificate, and it’s directly accessible by users for verification. This visible SSL indicator can substantially elevate user confidence, contributing to the perception of a secure and trustworthy website.

Moreover, SSL encryption plays a significant role as a positive ranking factor recognized by search engines, including Google, which prefer secure sites with HTTPS over unsecured ones. Thus, the implementation of SSL certificates contributes to better search engine rankings for websites, underlining the influence of SSL on visibility and web traffic.

HTTPS as a Standard: The New Norm for Web Security

The adoption of HTTPS, enabled by SSL certificates, represents a commitment to web security and has become the standard for websites. Using SSL certificates to enable HTTPS yields benefits such as stronger Google rankings, improved customer trust, and encrypted communication between users and websites.

The widespread availability of free SSL/TLS encryption options, such as those offered by Cloudflare, has contributed to the mass adoption of HTTPS, furthering the internet’s collective security.

Acquiring and Installing SSL Certificates
