🔐 Chrome is testing a new model of HTTPS certifications in preparation for the post-quantum era.
In a proactive step against the risks of quantum computing, Google Chrome is testing what’s known as Merkle Tree Certificates (MTCs) — a radically different mechanism than the traditional X.509 certification model.
The problem is clear: Integrating post-quantum signature algorithms within the X.509 series will result in a significant boom in certificate volume, meaning a significant increase in TLS handshake data and a direct impact on performance.
The suggested solution is based on the structure of Merkle Tree:
Instead of the credentialing book signing...

🌐 Networking Basics Every IT Professional Should Know

If you're starting your journey in Networking, CCNA, or Cybersecurity, understanding these core concepts is essential. This quick guide covers some of the most important building blocks of modern networks.

📌 Key Networking Concepts

🔹 Network – Connects multiple devices to share data and resources.
Types include LAN, WAN, and MAN.

🔹 Switches – Connect devices within a Local Area Network (LAN) and forward frames based on MAC addresses.

🔹 Router – Directs data packets between different networks using routing protocols.

🔹 VLAN (Virtual LAN) – Segments a network into multiple logical...
