SSL/TLS
Web security protocol
SSL/TLS is a pair of cryptographic protocols that secure internet communications.
SSL (Secure Sockets Layer) was the original; TLS (Transport Layer Security) is its successor and current standard.
Both encrypt data transmitted between browsers and servers, preventing eavesdropping.
The padlock icon in your browser indicates an SSL/TLS connection.
Though SSL is technically obsolete, people still say "SSL" when they mean TLS: Make sure your site has an SSL certificate.
