This encryption ensures that sensitive data, such as credit card details or login credentials, can&#8217;t be intercepted by malicious actors.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Although <\/span><b>SSL<\/b><span style=\"font-weight: 400;\"> has technically been succeeded by <\/span><b>TLS (Transport Layer Security)<\/b><span style=\"font-weight: 400;\">, the term &#8220;SSL&#8221; is still widely used when referring to the technology that secures websites with HTTPS.<\/span><\/p>\n<h2><b>SSL vs. TLS: What\u2019s the Difference?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">While SSL was the original encryption protocol, it has been deprecated in favor of TLS due to security vulnerabilities.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>SSL<\/b><span style=\"font-weight: 400;\">: First introduced in the 1990s.
