Cryptography studies secure communications techniques that allow only the sender and intended recipient of a message to view its contents. The term is derived from the Greek word “kryptos”, which means hidden. It is closely associated with encryption, which is scrambling ordinary text into what’s known as ciphertext and then back again upon arrival. In addition, cryptography […]
In a hacking attempt carried out by a security researcher, Lennert Wouters, at the Belgian university KU Leuven, the Starlink satellite-based internet system operated by SpaceX was successfully hacked. The most shocking thing is that it cost him approx 25 dollars only to make a homemade circuit board to hack the system. A series of […]

I recently read that SSH keys provide a secure way of logging into a Linux and Unix-based server. How do I set up SSH keys on a Linux or Unix-based system? In SSH for Linux/Unix, how do I set up public-key authentication? This page explains a public key and shows you how to set up […]
