Tag: Public Keys

In our increasingly Digital world, securing our communications and data is paramount. One of the foundational technologies that makes modern cybersecurity possible is public-key cryptography. This innovative approach, also known as asymmetric cryptography, uses a pair of keys – one public and one private – to provide authentication, encryption, and digital signatures. Understanding the principles behind public keys is essential for anyone navigating the complexities of online security. What is a Public Key? The Core Concept of Public-Key Cryptography Public-key cryptography, at its heart, relies on mathematical algorithms that are easy to compute in one direction but exceptionally difficult to reverse without specific information. Imagine a padlock: anyone can close it (encrypt a message)...
