What is the difference between SSL and TLS?

SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are protocols for securing network connections. TLS is a more modern and secure version of SSL.

Main differences:

• SSL is outdated and no longer used due to known vulnerabilities.
• TLS provides improved cryptography and security.
• TLS is backward compatible with SSL, but it is recommended to use only TLS (starting from version TLS 1.2 and above).

In practice today, SSL often refers to TLS, but it is important to understand that TLS is the current standard for encrypting traffic, for example, in HTTPS.
