SSL and TLS are two essential terms that frequently mentioned when discussing online security, particularly in relation to safeguarding data and digital communications. While the two terms are often used interchangeably, they actually have distinct differences that are important for website owners and security-conscious users to understand. Gaining a clear understanding of SSL and TLS, including how each functions, can help you make informed decisions when choosing the right security measures to protect sensitive information from threats like data breaches or interception. This article will break down their differences in a simple and accessible way, highlighting their critical role in maintaining your website’s security and credibility. What are SSL and TLS? SSL ensures that the data exchanged between users and websites, or between systems, remains secure and accessible only to authorized parties. By using encryption algorithms, SSL secures the data during transmission, making it harder for hackers to intercept and read. This protection covers various types of sensitive information, including credit card numbers, names, addresses, and more. On the other hand, TLS (Transport Layer Security) is an enhanced version of SSL, providing a higher level of security. Although most modern websites use TLS, the term SSL is still more commonly recognized by the public. Both serve the same purpose, which is to encrypt data to safeguard information during its transfer. What is the difference? Both are encryption protocols that safeguard data as it travels across the internet. However, TLS is the updated and more advanced version of SSL. Despite SSL being the more familiar term, the majority of current websites rely on TLS for enhanced data protection. Here are the summary of the difference : SSL (Secure Sockets Layer) TLS (Transport Layer Security) Development Timeline SSL has been phased out, progressing through versions 1.0 to 3.0. TLS is the successor to SSL, with versions ranging from 1.0 to 1.3. Current Status All versions of SSL are obsolete and no longer in use. TLS 1.2 and 1.3 are currently active and widely implemented. Security Alerts Only includes two types of unencrypted alerts. Supports encrypted and more varied alert messages. Data Authentication Uses Message Authentication Codes (MACs). Uses the more secure Hashed MACs (HMACs). Encryption Standards Relies on older, less secure cipher suites. Employs modern and robust encryption algorithms. Connection Process Involves a longer, more complicated handshake process. Offers a quicker, more streamlined handshake procedure. Which one should you choose? Both are essentially connected, with TLS being the more advanced version that developed from SSL. Even so, since TLS is less familiar to the general public, many still refer to it as SSL. That’s why the term SSL continues to be widely used. To sum up, both are vital for protecting data during online communication. To maximize your site’s security, it’s strongly advised to use an SSL/TLS certificate issued by a reputable provider. DigiCert TLS certificates come in multiple configurations to meet diverse use cases and security needs, including compliance with Payment Services Directive 2 (PSD2). By choosing a trusted TLS certificate provider, you not only protect sensitive data but also build trust with users who rely on you to keep their information safe.
