Backward compatibility is an important aspect when transitioning from SSL to TLS. TLS versions up to TLS 1.2 are backward compatible with SSL. This means that websites with SSL certificates can still function with TLS enabled. However, it is recommended to upgrade to TLS 1.2 for better security.
TLS 1.3 removed backward compatibility with SSL, making it exclusively a TLS-only protocol. This decision was made to eliminate the vulnerabilities associated with older SSL versions and ensure greater security.
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.
