Embracing the Future: Understanding the Superiority of TLS 1.3 Over TLS 1.2


Published on Nov 13, 2023   —   2 min read

In the realm of internet security, the Transport Layer Security (TLS) protocol plays a pivotal role in safeguarding communications. The evolution from TLS 1.2 to TLS 1.3 marks a significant leap forward in enhancing online security and performance. This blog post aims to elucidate the differences between these two protocols and underscore why TLS 1.3 is the preferred choice moving forward.

A Comparative Overview: TLS 1.2 vs. 1.3

TLS 1.2: The Foundation

Introduced in 2008, TLS 1.2 was developed to improve upon its predecessors by offering stronger security features:

  • Enhanced Cipher Suites: It introduced more effective cipher suites, which are combinations of algorithms used for encryption, key exchange, and authentication.
  • Robust Hashing Algorithms: TLS 1.2 employed SHA-256 and SHA-384 hashing algorithms, offering more security than the older SHA-1.
  • Improved Protocol Version Negotiation: This feature prevented the use of earlier, less secure protocols, thereby mitigating downgrade attacks.
