Released in 1995, <strong>SSL 2.0<\/strong> (<strong>SSL 1.0<\/strong> was never released) was the first widely used version but revealed serious security flaws. These included:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Vulnerability to downgrade attacks like <a href=\"https:\/\/www.hosted.com\/blog\/ssl-stripping-attack\/\" alt=\"Link to Hosted.com Blogs - What Is An SSL Stripping Attack And How To Prevent It\" title=\"Hosted.com - What Is An SSL Stripping Attack And How To Prevent It\" target=\"_blank\" rel=\"noopener\">SSL stripping<\/a>.<\/li>\n\n\n\n<li>Poor Message Authentication Code (<strong>MAC<\/strong>) made it susceptible to attacks that could alter data without detection.<\/li>\n\n\n\n<li>Weak cipher suites (combinations of encryption algorithms, key exchange methods, and hashing functions), meaning an attacker could easily break the encryption.<\/li>\n<\/ul>\n\n\n\n<p><strong>Note: MAC<\/strong> is a digital signature confirming the communication originated from the intended website.<\/p>\n\n\n\n<p>Improvements in the newer version, SSL 3.0, followed in 1996, but it also came with issues, such as gaps that let hackers decrypt data and steal sensitive information. This prompted major browsers to deprecate <strong>SSL<\/strong> and use <strong>TLS<\/strong> instead.<\/p>\n\n\n\n<p>The first version of <strong>TLS<\/strong> was an upgrade to <strong>SSL 3.0<\/strong> with several security improvements. However, it still contained vulnerabilities that led to attacks like <strong>BEAST<\/strong> (Browser Exploit Against SSL\/TLS).<\/p>\n\n\n\n<p><strong>TLS 1.1<\/strong> (2006) improved upon <strong>TLS 1.0<\/strong> by addressing some of these. <strong>TLS version 1.2<\/strong> (2008) was the next step up, and it included a more substantial security upgrade, supporting stronger cryptographic algorithms.<\/p>\n\n\n\n<p>This brings us to <strong>TLS 1.3<\/strong> (2018), the current industry standard for modern browsers (<strong>Google Chrome, Firefox, Safari, Edge<\/strong>), and mobile device operating systems. The latest version&#8217;s improvements include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The handshake process requires only one round-trip (<strong>RTT<\/strong>) instead of two.<\/li>\n\n\n\n<li>Removal of support for outdated and insecure algorithms.<\/li>\n\n\n\n<li>Encrypted handshake messages for better privacy.<\/li>\n\n\n\n<li>Improved performance with less connection latency.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading h3\" id=\"the-role-of-ssl-tls-certificates\">The Role of SSL &amp; TLS Certificates<\/h2>\n\n\n\n<p><strong>SSL\/TLS<\/strong> certificates establish an encrypted connection between a client (web browser) and a server\/website, protecting data travelling between the two from eavesdropping, tampering, and forgery. This is especially important for sensitive personal information, online banking, e-commerce transactions, and other financial data.<\/p>\n\n\n\n<p>The same applies to <a href=\"https:\/\/www.hosted.com\/blog\/what-is-ssl-email-securing-communications\/\" alt=\"Link to Hosted.com Blogs - What Is SSL Email - Securing Email Communications\" title=\"Hosted.com - What Is SSL Email - Securing Email Communications\" target=\"_blank\" rel=\"noopener\">secure email communications<\/a> that use protocols like <strong>SMTPS<\/strong>, <strong>POP3S<\/strong>, and <strong>IMAPS<\/strong> to protect content and attachments.

Though <strong>TLS vs SSL handshakes<\/strong> differ in some technical details, they follow the same general sequence. Here&#8217;s how <strong>SSL<\/strong> certificates work in real time:<\/p>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"1-client-hello\">1: Client Hello<\/h3>\n\n\n\n<p>The browser begins the connection (usually using <strong>port 443<\/strong>) by sending a <strong>Client Hello message<\/strong> containing information about its capabilities, including:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>The highest protocol version it supports.<\/li>\n\n\n\n<li>A random number for generating the session keys later.<\/li>\n\n\n\n<li>A list of suggested cipher suites.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"2-server-response\">2: Server Response<\/h3>\n\n\n\n<p>The server responds with:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>The highest mutually supported protocol version.<\/li>\n\n\n\n<li>Another random number for session key generation.<\/li>\n\n\n\n<li>The selected cipher suite from the client&#8217;s list that it supports.<\/li>\n\n\n\n<li>The digital certificate containing the server&#8217;s public key<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"3-certificate-verification\">3: Certificate Verification<\/h3>\n\n\n\n<p>The client verifies the server&#8217;s digital certificate by checking whether a trusted Certificate Authority (<strong>CA)<\/strong> issued it, its validity and expiration date. It also checks if the domain name in the certificate matches the actual domain name of the website being accessed and if the digital signature on the certificate is verified using the <strong>CA<\/strong>&#8216;s public key.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hosted.com\/blog\/wp-content\/uploads\/2025\/05\/tls-vs-ssl-3-1024x229.webp\" alt=\"Strip Banner Text - Despite different names, modern SSL certificates use TLS encryption.\" title=\"Despite different names, modern SSL certificates use TLS encryption.\" class=\"wp-image-8917\" width=\"1024\" height=\"229\" srcset=\"https:\/\/www.hosted.com\/blog\/wp-content\/uploads\/2025\/05\/tls-vs-ssl-3-1024x229.webp 1024w, https:\/\/www.hosted.com\/blog\/wp-content\/uploads\/2025\/05\/tls-vs-ssl-3-300x67.webp 300w, https:\/\/www.hosted.com\/blog\/wp-content\/uploads\/2025\/05\/tls-vs-ssl-3-768x172.webp 768w, https:\/\/www.hosted.com\/blog\/wp-content\/uploads\/2025\/05\/tls-vs-ssl-3-1536x343.webp 1536w, https:\/\/www.hosted.com\/blog\/wp-content\/uploads\/2025\/05\/tls-vs-ssl-3-2048x458.webp 2048w, https:\/\/www.hosted.com\/blog\/wp-content\/uploads\/2025\/05\/tls-vs-ssl-3-960x214.webp 960w, https:\/\/www.hosted.com\/blog\/wp-content\/uploads\/2025\/05\/tls-vs-ssl-3-603x135.webp 603w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"4-key-exchange\">4: Key Exchange<\/h3>\n\n\n\n<p>The exchanged information allows the client and server to agree on the pre-master secret, which will be used to generate the session keys.

These keys will encrypt and decrypt the application data exchanged after the handshake. A <strong>TLS handshake<\/strong> uses asymmetric encryption, which means that two different keys are used instead of symmetric encryption, which uses the same key for both.<\/p>\n\n\n\n<p>Both parties send encrypted <strong>Finished<\/strong> messages to verify that the handshake was successful, and that the encryption works correctly.<\/p>\n\n\n\n<p>After the handshake, a secure channel is established, and all communications are encrypted using the established session keys.<\/p>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"security-features-of-tls-ssl\">Security Features of TLS &amp; SSL<\/h3>\n\n\n\n<p>Both <strong>TLS<\/strong> vs <strong>SSL<\/strong> protocols implement several security features to protect private and personal data during transfer:<\/p>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"encryption-protocols\">Encryption Protocols<\/h3>\n\n\n\n<p>The main function of both <strong>TLS<\/strong> vs <strong>SSL<\/strong> is data encryption. They convert plaintext data into ciphertext, which appears as a random string of characters to anyone who may intercept it. Only the intended recipient (browser\/server) with the corresponding key can decrypt the ciphertext back to readable plaintext.<\/p>\n\n\n\n<p>Encryption methods have evolved significantly from older versions of <strong>SSL<\/strong> to modern <strong>TLS<\/strong> connections.<\/p>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"authentication\">Authentication<\/h3>\n\n\n\n<p>The authentication process ensures that the server and site you&#8217;re connecting to are precisely the ones you intended. This also helps prevent Man-In-The-Middle (<strong>MITM<\/strong>) and <strong><a href=\"https:\/\/en.wikipedia.org\/wiki\/Phishing\" alt=\"Link to Wikipedia - Phishing\" title=\"Wikipedia - Phishing\" target=\"_blank\" rel=\"noopener\">phishing attacks<\/a><\/strong>, where scammers pose as legitimate websites.<\/p>\n\n\n\n<p>Authentication is done through the digital certificates issued by trusted Certificate Authorities (<strong>CAs<\/strong>) that contain:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The website&#8217;s public key.<\/li>\n\n\n\n<li>Domain name information.<\/li>\n\n\n\n<li>The certificate owner.<\/li>\n\n\n\n<li>The <strong>CA<\/strong>\u2019s digital signature.<\/li>\n\n\n\n<li>Validity dates.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"data-integrity\">Data Integrity<\/h3>\n\n\n\n<p><strong>Secure Socket Layer<\/strong> and <strong>TLS<\/strong> certificates ensure data isn&#8217;t altered during transmission by implementing <strong>MACs<\/strong> to verify that what is received is identical to what was sent.<\/p>\n\n\n\n<p>If any part of the data changes during the transfer, the integrity check will fail, and the connection will be rejected to prevent tampering.<\/p>\n\n\n\n<h2 class=\"wp-block-heading h3\" id=\"the-key-differences-between-tls-vs-ssl\">The Key Differences Between TLS vs SSL Certificates<\/h2>\n\n\n\n<p>As we\u2019ve discussed, while often used interchangeably, <strong>TLS<\/strong> and <strong>SSL<\/strong> are different security protocols.<\/p>\n\n\n\n<p>The main difference is that <strong>TLS<\/strong> is the modern, secure successor to <strong>SSL<\/strong> because of those security vulnerabilities we mentioned earlier, and all SSL versions are no longer supported. However, when you purchase an <strong>SSL<\/strong> certificate, it will almost always support the latest <strong>TLS<\/strong> protocols.<\/p>\n\n\n\n<p>The <strong>TLS encryption<\/strong> we use today offers better security features, including improved authentication methods, stronger cipher suites and encryption algorithms, and protection against <strong>SSL <\/strong>protocol vulnerabilities.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Security Level: TLS<\/strong> offers significantly stronger mechanisms than <strong>SSL<\/strong> to secure web traffic.<\/li>\n\n\n\n<li><strong>Alert System: TLS <\/strong>has a better alert system that provides specific information about potential errors or security issues during connection and diagnosing attack attempts.<\/li>\n\n\n\n<li><strong>Record Protocol: TLS<\/strong> uses <strong>HMAC<\/strong> (Hash-based Message Authentication Code) for message authentication, while <strong>SSL<\/strong> uses a more vulnerable <strong>MAC<\/strong> algorithm.<\/li>\n\n\n\n<li><strong>Handshake Process: TLS<\/strong> has an improved handshake process that is more secure and requires fewer round trips. This speeds up connections, contributing to a better user experience and reduced server load.<\/li>\n<\/ul>\n\n\n\n<p>It also resumes sessions more efficiently, which allows clients and servers to re-establish a secure connection much faster without a full <strong>TLS<\/strong> handshake, improving performance.<\/p>\n\n\n\n<p>Encryption methods have improved significantly since the early versions of <strong>SSL<\/strong>. <strong>SSL<\/strong> initially used relatively weak encryption algorithms such as <strong>RC4<\/strong> and <strong>DES<\/strong>. Today, <strong>TLS<\/strong> uses stronger encryption standards, including <strong>AES<\/strong> (Advanced Encryption Standard) with <strong>128-bit<\/strong> or <strong>256-bit<\/strong> keys.<\/p>\n\n\n\n<h2 class=\"wp-block-heading h3\" id=\"benefits-of-using-tls-ssl\">Benefits of Using TLS or SSL Certificates<\/h2>\n\n\n\n<p>The biggest benefit of <strong><a href=\"https:\/\/www.hosted.com\/blog\/need-an-ssl-certificate-for-a-website\/\" alt=\"Link to Hosted.com Blogs - Do I Need An SSL Certificate For A Website\" title=\"Hosted.com - Do I Need An SSL Certificate For A Website\" target=\"_blank\" rel=\"noopener\">TLS vs SSL <\/a><\/strong><a href=\"https:\/\/www.hosted.com\/blog\/need-an-ssl-certificate-for-a-website\/\" alt=\"Link to Hosted.com Blogs - Do I Need An SSL Certificate For A Website\" title=\"Hosted.com - Do I Need An SSL Certificate For A Website\" target=\"_blank\" rel=\"noopener\">for your website<\/a> is the encryption that protects sensitive data from theft and keeps it private.
