What is TLS?

TLS is a reference to Transportation Layer Security and is the successor of SSL (Secure Sockets Layer). TLS ensures secure communications between servers and browsers. The connection itself is safe since symmetric cryptography is employed to secure the information transmitted. Keys are generated uniquely for each connection and built using a secret shared by all parties that is negotiated before the beginning in the course of the connection. This is often called a TLS handshake. Assistance

SSL/TLS certificates provide the power behind what people simply refer to as HTTPS. It appears on the address bar.

TLS 1.3 as compared with TLS 1.2

Businesses like Cloudflare are currently providing TLS 1.3 accessible to their customers. Filippo Valsorda gave a wonderful presentation (see the presentation below) regarding the distinctions between TLS 1.2 and TLS 1.3. The main advantages of TLS 1.3 in comparison to the TLS 1.2 is speedier speeds and enhanced security.

The other benefit is that in a sense, it will remember! If you've been to a website, it will remember! You can send data as the initial message you send to the server. It is known as"zero round trip. "zero round trip." (0-RTT). It will improve loading times.

Enhance Security With TLS 1.3

One of the main issues of TLS 1.2 is that it's frequently not properly configured, which exposes websites to attacks. TLS 1.3 now removes obsolete and unsecure functions from TLS 1.2 that include:

  • SHA-1
  • RC4
  • DES
  • 3DES
  • AES-CBC
  • MD5
  • Arbitrary Diffie Hellman groups CVE-2016-0701
  • EXPORT-strength-ciphers are responsible the ciphers for FREAK and LogJam

Because the protocol is more straightforward which makes it less likely for programmers or administrators to make mistakes in the development for the protocols. Jessie Victors, a security consultant, specializing in privacy-enhancing technology and cryptography applied stated:

I'm excited about the upcoming standard. I am convinced that we will see lesser security flaws and trust TLS much higher than previously.

Google is raising the standard. They have been warning users via their search consoles that they're moving to TLS version 1.2 to make sure that TLS 1 does not seem to be the safest. They've set a date in March of 2018.

TLS 1.3 browser support

Chrome has provided the initial release of TLS 1.3 since Chrome 65. With the Chrome 70 version (released in October 2018,) it was the final version of TLS 1.3 was enabled for connection outgoing.

The first release of TLS 1.3 was enabled in Firefox 52 and above (including Quantum). It was using the insecure fallback TLS 1.2 until they learned more about server tolerability and TLS 1.3. 1.3 handshake. Firefox 53 (released in October 2018) was released with the latest version of TLS 1.3.

Microsoft Edge started supporting TLS 1.3 in version 76 and it is turned on by default for Safari 12.1 with macOS 10.14.4.

In addition, certain SSL tests that are available through the Internet do not support TLS 1.3 currently as of yet, nor do other browsers like IE as well as Opera mobile.

It may take some time to allow the other browsers to be able to catch up. Most browsers are in development currently. Cloudflare offers a great blog about the reasons TLS 1.3 isn't available in browsers yet.

However, on the 11th of September, 2018, TLS 1.3 surpassed TLS 1.0 in the ranking of the second most used version at Cloudflare.

TLS 1.3 Server Support

If you're trying to determine the server or hosting provider is compatible with TLS 1.3 but, it is possible to make use of the SSL Test tool. The test software is available for download. You just need to scan your domain and scroll down into the "Protocol Features" section. The application will either say"yes" or "no".

TLS 1.3 Support

Our CDN partner, KeyCDN, launched TLS 1.3 that supports 0-RTT, on September 27, 2018. This support was added to the media and assets delivered by the CDN.

In the month of August, we introduced the TLS 1.3 support on all our servers. Now, you can take advantage of the performance as well as security features of TLS 1.3.
