What is SSL Certificate
An SSL (Secure Sockets Layer) certificate is a digital certificate that establishes a secure encrypted connection between a web server and a web browser. SSL certificates are used to protect sensitive information such as login credentials, credit card details, and personal data.
SSL certificates contain important information, including the certificate holder’s name, a unique serial number, expiration date, and a digital signature from the certificate issuer.
When a web browser attempts to connect to a website secured with SSL, the browser requests that the web server identify itself. The web server sends the SSL certificate to the browser, which verifies that the certificate is valid and issued by a trusted certificate authority (CA). If the certificate is valid, the browser establishes a secure encrypted connection with the web server, allowing secure transmission of sensitive information between the two parties.
Overall, SSL certificates play an important role in securing online communications and protecting user data from interception and tampering.
Where to Buy a SSL certificate
SSL certificates can be purchased from a variety of reputable sources, including certificate authorities (CAs), web hosting providers, and online SSL certificate resellers. Some popular options include:
- Certificate Authorities (CAs): Some well-known CAs that offer SSL certificates include DigiCert, Symantec, Comodo, GlobalSign, and GeoTrust. You can purchase SSL certificates directly from these CAs, but they may be more expensive than other options.
- Web Hosting Providers: Many web hosting providers offer SSL certificates as part of their hosting packages. For example, popular providers such as Bluehost, SiteGround, and HostGator offer SSL certificates for free or at a discounted rate.
- Online SSL Certificate Resellers: There are also several online resellers that offer SSL certificates at competitive prices, including SSL.com, SSLs.com, and Namecheap.
Before purchasing an SSL certificate, it’s important to determine the type of certificate that best suits your needs (e.g. single domain, wildcard, or EV SSL), as well as the level of validation and support required. Additionally, make sure to choose a reputable vendor that offers high-quality certificates and reliable customer support.
Where to Get Free SSL Certificate
There are several options to get free SSL certificates, including:
- Let’s Encrypt: Let’s Encrypt is a non-profit organization that provides free SSL certificates. The certificates are automatically issued and can be easily installed on your website using tools such as Certbot.
- Cloudflare: Cloudflare provides a free SSL certificate through their SSL/TLS service. The certificate is easy to set up and offers several security features, including DDoS protection and a web application firewall.

- ZeroSSL: ZeroSSL offers a free SSL certificate that is valid for 90 days. The certificate can be easily generated and installed on your website using their online tools.
It’s important to note that while free SSL certificates can provide basic encryption and security for your website, they may not offer the same level of features and support as paid certificates. Additionally, some web hosting providers may offer free SSL certificates as part of their hosting package, so it’s worth checking with your provider to see if this is an option.
What is an SSL Certificate Used for
An SSL (Secure Sockets Layer) certificate is used to establish a secure encrypted connection between a web server and a web browser. SSL certificates are used to protect sensitive information, such as login credentials, credit card details, and personal data, transmitted between the web server and the browser.
When a website is secured with SSL, it will have an HTTPS URL instead of the regular HTTP. The HTTPS protocol indicates that the website has a valid SSL certificate, and that the data being transmitted between the web server and the browser is encrypted and secure.
SSL certificates also play a crucial role in maintaining the trust and security of online transactions. Websites that handle sensitive information, such as e-commerce sites, banking sites, and government sites, are required to have SSL certificates to protect users’ data from interception and tampering.
Overall, SSL certificates are used to provide secure communication and encryption between web servers and web browsers, protecting sensitive information and ensuring the privacy and security of online transactions.
What is Free SSL Certificate
A free SSL (Secure Sockets Layer) certificate is a digital certificate that can be obtained without cost, typically from a certificate authority (CA) or a third-party SSL certificate provider. Free SSL certificates provide the same level of encryption and security as paid SSL certificates, but they are issued with a shorter validity period, ranging from a few weeks to a few months.
Free SSL certificates are often used by small businesses, personal blogs, and non-profit organizations that want to secure their website but may not have the budget to purchase a paid SSL certificate. In addition, many web hosting providers and website builders now offer free SSL certificates as part of their hosting packages, making it easy for website owners to secure their sites with HTTPS.
It’s important to note that while free SSL certificates can provide basic encryption and security for your website, they may not offer the same level of features and support as paid certificates. Additionally, free SSL certificates typically do not include the same level of validation and trust as paid certificates, which may be important for certain types of websites or businesses.
How to Check Website SSL Certificate
To check a website’s SSL (Secure Sockets Layer) certificate, follow these steps:

Click on the padlock icon to view details about the SSL certificate. This will open a pop-up window that displays information about the certificate, such as the name of the certificate authority (CA) that issued the certificate, the expiration date of the certificate, and the level of encryption used.
Verify that the information in the SSL certificate matches the information for the website. Make sure that the domain name in the SSL certificate matches the domain name of the website you are visiting.
If you want to view more detailed information about the SSL certificate, you can click on the “View Certificate” or “Certificate Information” link in the pop-up window. This will display more detailed information about the SSL certificate, including the public key, the certificate chain, and the certificate revocation status.

How to Fix SSL Certificate Error
An SSL (Secure Sockets Layer) certificate error can occur for a variety of reasons, but the following steps can help you troubleshoot and fix common SSL certificate errors:
- Check the SSL certificate expiration date: If the SSL certificate has expired, you will need to renew it with your certificate provider or web hosting company. If the certificate is still valid, proceed to the next step.
- Check the SSL certificate chain: SSL certificates are typically issued by a trusted certificate authority (CA), and the certificate chain must be properly configured to ensure that the certificate is recognized as valid by web browsers. Use an SSL checker tool to verify that the certificate chain is properly configured and that all intermediate certificates are installed correctly.
- Check for mixed content: If your website includes content (such as images or scripts) that is hosted on a non-secure server, web browsers may display an SSL certificate error. Use a tool like the Qualys SSL Labs SSL Test to check for mixed content on your website.
- Clear your web browser cache: Sometimes SSL certificate errors can be caused by issues with your web browser’s cache. Clearing your cache can help resolve these issues. You can typically clear your cache by going to the settings or options menu in your web browser.
- Try accessing the website from a different web browser or device: If the SSL certificate error persists, try accessing the website from a different web browser or device. This can help you determine if the error is specific to one browser or device, or if it is a more widespread issue.
- Contact your web hosting company or SSL certificate provider: If you have tried all of the above steps and the SSL certificate error still persists, contact your web hosting company or SSL certificate provider for assistance. They may be able to provide more detailed troubleshooting steps or help you resolve the issue directly.
