SSL (Secure Sockets Layer) is a security protocol that is used to establish encrypted links between a web server and a browser. This ensures that all data that is transmitted between the two parties remains private and secure. To check the SSL version of a website, you can use a variety of online tools or browser extensions.
It is important to check the SSL version of a website before you enter any sensitive information, such as your credit card number or password. This is because older versions of SSL are more vulnerable to attack. By checking the SSL version, you can help to protect your personal information from being stolen.
The first version of SSL was released in 1994. Since then, there have been several updates to the protocol, each of which has improved its security. The current version of SSL is TLS 1.3, which was released in 2018.
To check the SSL version of a website, you can use a variety of online tools or browser extensions. Some popular tools include:
- SSL Labs
- DigiCert SSL Checker
- GlobalSign SSL Checker
Once you have chosen a tool, simply enter the URL of the website that you want to check into the search bar. The tool will then scan the website and provide you with a report that includes the SSL version.
If you are using a browser extension, you can simply click on the extension icon in your browser’s toolbar. The extension will then scan the website that you are currently visiting and provide you with the SSL version.
Checking the SSL version of a website is a simple and effective way to protect your personal information. By taking this simple step, you can help to ensure that your data is safe and secure.
