But there are important differences between them.<\/p>\n<p><strong>SSL (Secure Sockets Layer)<\/strong> is an older technology used when web security was originally built. Today, it is considered obsolete and is no longer used.<\/p>\n<p><strong>TLS (Transport Layer Security)<\/strong> is a more modern and secure development of SSL. It is TLS that is now used by all major websites and online services. Any website that starts with https:\/\/ uses TLS, although many people still say \u201cSSL\u201d because it\u2019s the more familiar term.<\/p>\n<h3>The history of SSL &#038; TLS<\/h3>\n<ul>\n<li><strong>SSL 1.0<\/strong> was never released &#8211; it had serious vulnerabilities.<\/li>\n<li><strong>SSL 2.0<\/strong> appeared in 1995 but quickly became obsolete.<\/li>\n<li><strong>SSL 3.0<\/strong> was released in 1996 and became more reliable, but it was soon replaced.<\/li>\n<li><strong>TLS 1.0<\/strong> became the official successor to SSL in 1999.<\/li>\n<li><strong>TLS 1.1<\/strong> and 1.2 gradually strengthened security and eliminated old vulnerabilities.<\/li>\n<li><strong>TLS 1.3<\/strong> (released in 2018) is the current standard, providing both high security and faster operation.<\/li>\n<\/ul>\n<h3>Key differences between TLS and SSL<\/h3>\n<table>\n<tbody>\n<tr>\n<td><strong>Characteristic<\/strong><\/td>\n<td><strong>SSL<\/strong><\/td>\n<td><strong>TLS<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>Status<\/strong><\/td>\n<td>Outdated<\/td>\n<td>Modern standard<\/td>\n<\/tr>\n<tr>\n<td><strong>Encryption<\/strong><\/td>\n<td>Uses weaker algorithms<\/td>\n<td>Uses strong, reliable algorithms<\/td>\n<\/tr>\n<tr>\n<td><strong>Performance<\/strong><\/td>\n<td>Slower<\/td>\n<td>Faster connection establishment<\/td>\n<\/tr>\n<tr>\n<td><strong>Message authentication<\/strong><\/td>\n<td>Based on MD5<\/td>\n<td>Uses HMAC (more secure)<\/td>\n<\/tr>\n<tr>\n<td><strong>Browsers support<\/strong><\/td>\n<td>Almost absent<\/td>\n<td>Supported by all<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>What about SSL certificates?<\/h3>\n<p>The name &#8220;SSL certificate&#8221; has stuck, but all modern certificates use TLS. That is, when you buy an SSL certificate today, you get protection via TLS &#8211; they just haven&#8217;t changed the term due to habit and marketing.<\/p>\n<h3>Conclusion<\/h3>\n<p>While SSL was the first step towards a secure internet, its era is long gone. Today, online communications are secured by TLS, a protocol that is fast, reliable, and secure against modern threats. If you are creating a website, working with sensitive data, or simply want to protect your users, you need TLS. Fortunately, it is already built into every modern SSL certificate.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Regarding online security, especially when transmitting personal or financial information, two key protocols come into play: SSL and TLS.
