TLS 1.3 is the latest version of the cryptographic protocol, approved by IETF, bringing significant improvements over TLS 1.2 in terms of security and speed. It offers a faster handshake process with options like 0-RTT resumption, drastically reducing connection times. The transition to TLS 1.3 is imminent as major browsers prepare for its adoption, promising a more secure internet experience.

- 2. 2 TLS 1.3 is here, and we’re in safe hands
- 3. 3 Why TLS 1.3? LAUNCH Browser Support TLS 1.2 Improvement Soon, TLS 1.3 will be adopted by all leading browsers and will soon become a reality from the theoretical concept it is. Needless to say, TLS 1.3 brings a host of improvements over TLS 1.2, the current occupant of the SSL/TLS family. TLS 1.3, the latest and unsurprisingly the most advanced cryptographic protocol till date, has finally been approved by the IETF (Internet Engineering Task Force).
- 4. 4 SecureFaster Why TLS 1.3 is Faster and Secure? When it comes to browsing the internet, two things matter above else. These things are security and speed. TLS 1.3, with its faster handshake and security advancements, excels at both. It sheds away the insecure skin of TLS 1.2 and its predecessors and offers a quicker, secure way to communicate in the precarious world of internet.
- 5. 5 Why TLS 1.3 is more secure?
- 6. 6 TLS 1.2 is not broken TLS 1.2 TLS 1.2 Pitfalls TLS 1.2 isn’t broken TLS 1.3 with no Pitfalls TLS 1.2 is broken. It’s definitely not broken. TLS 1.3 eliminates such possibility as it doesn’t consist of such obsolete components. TLS 1.2, with all its benefits and successful serving tenure, has its pitfalls. These pitfalls come in the form of insecure protocols, ciphers, and algorithms.

- 8. 8 Less traveling = More speed TLS Handshake Encrypted communication This handshake involves a series of back-and-forth communication and verification steps between both entities. During these steps, they come to terms of data transfer and pave the way for encrypted communication. As good as this sounds, it comes with a constraint – SPEED. For a TLS-enabled secure connection to take place, a process named ‘TLS handshake’ must take place between the client and the server.
- 9. 9 As a result, it takes a bit more time to perform the handshake and establish a secure connection. The TLS 1.2 handshake incorporates two round- trips of communication between server and client. To give you a number, it takes around 0.25 to 0.5 seconds for it. This may not look like a lot on paper, but it can make some serious difference in reality as the data transfer takes place after the handshake. TLS 1.2 handshake
- 10. 10 TLS 1.3 introduces 1-RTT handshake that cuts the handshake time by almost half. With TLS 1.3, we’re about to see a radical change in the handshake time. In areas where even a microsecond can make a world of a difference, this is nothing less than a boon. As good as the 1-RTT handshake is, it’s 0-RTT Resumption that has stolen the thunder from it. TLS 1.3 handshake
- 11. 11 If the server and client have come across each other before, the handshake will be of zero round-trips. 0-RTT Resumption is accomplished by using the stored information such as session IDs. Yes, a handshake consisting of zero round-trips! This takes the handshake time down to the bottom. This way unprecedented connection speed will be achieved with the introduction of TLS 1.3.

- 13. 13 Thankfully, it’s been passed by IETF, and it’s become a question of ‘when’ instead of ‘if.’ Thanks to IETF There’s no doubt about the fact that the internet will be a better place when TLS 1.3 arrives.
