What’s new in post-quantum cryptography in RHEL 10.1

by No author

In May 2025, Red Hat Enterprise Linux 10 (RHEL) shipped with the first steps toward post-quantum cryptography (PQC) to protect against attacks by quantum computers, which will make attacks on existing classic cryptographic algorithms such as RSA and elliptic curves feasible. Cryptographically relevant quantum computers (CRQC) are still not known to exist, but that does not mean the risk is zero. For example, "harvest now, decrypt later" attacks do not need a quantum computer now, one only needs to become available before the stored encrypted data loses its value, and depending on the transferr

From if to how: A year of post-quantum reality

by No author

For the last 5 years, post-quantum cryptography (PQC) has largely been discussed as a research topic. It was a question of if—if the standards are ratified, if the algorithms perform, if the threat is real.In 2025, Red Hat changed the conversation. We stopped asking “if” and started defining “how.” This past year, we moved PQC out of the laboratory and into the operating system (OS). It wasn’t just about upgrading libraries, it was about pushing the entire modern software supply chain. We found that while the foundation is ready, the ecosystem has a long way to go.Here is the story

RPM and DNF features and enhancements in Red Hat Enterprise Linux 10.1

by No author

Red Hat Enterprise Linux 10.1 (RHEL) features some significant updates to RPM and DNF, two technologies designed to help you manage software installs and updates. The RPM package manager (RPM) creates installation files used to install and uninstall an application, and that can be queried for information about what libraries and binaries the application contains. The dnf command is the tool used on RHEL to search for available applications, and then to install, update, or uninstall them. These are important components of a computer system, so we've worked hard to improve them.RPM signature imp

Beyond modularity and other upgrades: The game-changer for your IT planning

by No author

Scott and I talk to a lot of customers, and one theme that comes up over and over is that it’s difficult to plan for future releases of Linux. Sometimes, support drops for a feature or capability on which they rely. Other times, it’s that they can’t wait for a new feature, bug fix, and so on. Planning for Red Hat Enterprise Linux (RHEL) with its built-in digital roadmap, powered by Red Hat Lightspeed, is changing that. Product managers within RHEL now communicate directly with you about upcoming changes in the code base. This gives you more time to plan for changes, as well as clearer in

Deterministic performance: Why Red Hat Enterprise Linux is the engine for industrial edge

by No author

In industrial environments, the drive toward smart manufacturing means blending the worlds of operational technology (OT) and information technology (IT). To this point, these worlds have existed in silos—OT managing the physical, real-time control of machinery, and IT focusing on data, security, and enterprise efficiency.But today, the industrial edge depends on this convergence. This unification demands a reliable platform that provides low latency as well as predictable latency—what we call deterministic performance. Determinism means that a high-priority task, like motion control or

Alliander modernises its electricity grid with Red Hat for long-term reliability in balance with rapid innovation

by No author

Long‑lasting transformers and short‑lifecycle IT are not a natural pairing. Utilities run process installations designed to last for decades, while the control software ages far faster. Deferring replacement isn’t an option, because operations must stay online with up‑to‑date security. So how do you resolve this? How can you procure operational technology (OT) – the technology that runs the power grid – today with confidence it will still run reliably by 2035?

Navigating the industrial edge: How a platform approach unlocks business value

by No author

When I talk to industrial customers, a consistent theme emerges: the world of operational technology (OT) is undergoing a rapid, often-daunting transformation. For decades, OT environments have been built on proprietary, siloed systems, prized for their stability and longevity. But as we see technology power improvements in efficiency, productivity, and cost reduction, the pressure to evolve is immense. It's no longer just about keeping the factory running; it's about making it smarter, more agile, and more resilient.This shift presents a unique challenge for IT managers and business leaders.
