Java 26 has just been released! (depending on your timezone), but work on Java 27 is already on the way. The first JEP of the new release is JEP 527: Post-Quantum Hybrid Key Exchange for TLS 1.3.

JEP 527 (Post-Quantum Hybrid Key Exchange for TLS 1.3) is a Java enhancement designed to protect your internet communications from future quantum computers.

Here is the breakdown in easy terms:

1. The Problem: “Harvest Now, Decrypt Later”

Today, when you connect to a website (using HTTPS/TLS), the “key exchange” that secures your connection uses math (RSA or Elliptic Curve) that is very strong for current computers but could be cracked by a powerful quantum computer in the future.
