SSL encryption is crucial for informational sites and blogs, even if they do not collect payments or sensitive information. Implementing HTTPS, the secure version of the HTTP protocol, ensures that user activity remains private and protected from third-party entities.

There are different versions of the SSL/TLS protocols, each with varying security levels. The SSL versions 1.0, 2.0, and 3.0 are considered insecure and susceptible to attacks. TLS 1.0 was introduced as an upgraded version, followed by subsequent versions that addressed security flaws and improved encryption protocols.

For informational sites and blogs, it is essential to transition from outdated and vulnerable SSL versions to a more secure TLS protocol. TLS 1.2 offers backward compatibility with SSL, allowing websites with SSL certificates to continue functioning. However, upgrading to TLS 1.2 or the latest version, TLS 1.3, is highly recommended for optimal security.
