The post-quantum cryptography (PQC) transition is well underway in Red Hat Enterprise Linux (RHEL). In May 2025, RHEL 10 delivered post-quantum key exchange algorithms in three major cryptography libraries (OpenSSL, GnuTLS, and NSS), making post-quantum key exchange usable in TLS 1.3 connections. RHEL 10.1 followed, setting the new key exchange algorithms as default in TLS, and introducing post-quantum signatures for RPM packages.The secure shell (SSH) protocol was not left behind. RHEL 10 shipped with OpenSSH 9.9, supporting two hybrid post-quantum key exchange methods: sntrup761x25519-sha512
Nearly two years ago, we launched image mode for Red Hat Enterprise Linux (RHEL) to give customers a simpler way to deploy the foundation of their IT enterprise. Since then, I’ve heard users who have adopted image mode describe it as a lifestyle change. There's a fundamental shift in thinking from package-based management to container-native, image-based management. And let's face it, lifestyle changes can be difficult. But the benefits—technical and personal—are real.Image mode makes some of IT’s most tedious processes simpler. That means more predictable operations for the enterprise
