Every time you connect to a Wi-Fi network, send a message through an encrypted app, or access your bank account online, you're relying on encryption to keep your data safe. At the heart of this digital security infrastructure stands the Advanced Encryption Standard (AES) — the encryption algorithm...
Introduction Data breaches have become routine: millions of users worldwide face the consequences of compromised passwords. The scale is staggering: billions of credentials are exposed, fueling automated attacks and credential stuffing on a massive scale. Services like "Have I Been Pwned" now...
Symmetric algorithms, forming the backbone of modern cryptography, offer a secure method of encrypting and decrypting data utilizing a single shared key. They have been widely adopted for their unmatched speed and efficiency. Like any other technology, symmetric algorithms come with their own set...
If you've heard of ‘SHA’ in various forms but aren't sure what it stands for or why it's essential — you’re in luck! We'll attempt to shed some light on the family of cryptographic hash algorithms today. But, before we get into SHA, let's go over what a hash function is and how it works. Before...
If the concept of ‘quantum cryptography' sounds complicated to you, you're right. That’s why this ‘encryption tutorial for dummies’ shall demystify the concept and provide an explanation in layman’s terms. Quantum cryptography, which has been around for a few decades, is becoming more and more...
End-to-end encryption has been introduced by many communication providers in recent years, notably WhatsApp and Zoom. Although those companies have tried to explain the concept to their user base several times, we believe they failed. Whilst it's clear that these platforms have increased security,...
In this year of our lord, 2022, the term ‘Zero-Knowledge Encryption’ equates to best-in-class data insurance. We’ve already written an article named “What is Zero-Knowledge Proof?”, so we’re not going to look at definitions here, but rather, we’re going to explore the pros and cons of...
It is rare for technologies to be born from ambitious philosophical concepts or mind games. But, when it comes to security and cryptography – everything is a riddle. One of such riddles is ‘How can you prove that you know a secret without giving it away?’. Or in other words, ‘how can you tell...
