What Is the Difference Between SSL & TLS?

What Is the Difference Between SSL & TLS? thumbnail
The SSL and TLS protocols make Internet transmissions more secure.

The Secure Sockets Layer and Transport Layer Security protocols are often abbreviated SSL and TLS, respectively. The SSL protocol preceded TLS, which is based on the current standard version of SSL called SSL 3.

  1. Function

    • Both SSL and TLS allow Web servers and Web clients, such as browsers, to share information securely by encrypting data to make it private after confirming the identity of the server. Since TLS is an open standard, it will probably enjoy wider use in the future because people are free to adapt it to their specific needs, according to LuxSci.

    Features

    • The SSL and TLS protocols employ authentication, encryption and handshake procedures to transmit data securely over the Internet. Connections using SSL activate security features that require a specific port to be secure. In contrast, connections using TLS may be either insecure or secure, both of which can occur over an identical port.

    Considerations

    • While SSL and TLS provide similar functionality, they are not interchangeable. The TLS protocol is backwards compatible with SSL, however, which means it works with client-server connections that require SSL. Yet, SSL does not work with client-server connections that require TLS.
