Have you ever wondered how your online data stays safe? The answer often starts with SHA (Secure Hash Algorithm). It plays a leading role in password storage, SSL certificates, digital signatures, and blockchain technology. Whether you know it or not, you interact with it every day. This article explains what SHA is, how it works, […]
Think of encryption as sending a secret message in a bottle. You have two ways to secure it: seal the entire message in one go (like a block cipher) or encode it letter by letter (like a stream cipher). Both methods protect your data, but they work in fundamentally different ways. Nowadays, understanding the difference […]
You rely on encryption whenever you check your email, browse the web, or pay online. But how does that protection actually work? That’s where elliptic curve cryptography comes in. It’s a modern public key encryption that offers strong online security without demanding too much computing power. More services now choose ECC over older systems like […]
You’ve probably hesitated before entering your credit card details on a site that didn’t “feel” right. That hesitation is genuine, and most online shoppers share it. Trust is the foundation of every click, form, and transaction in a space riddled with scams and data breaches. That’s where a trust seal steps in. It helps create […]
Staying safe online starts with encryption. Whether you’re sending a private message, browsing a secure website, or managing blockchain data, strong cryptographic tools protect your information. Two of the most widely used methods today are ECDSA and RSA. Both are powerful, well-tested, and built for asymmetric encryption. But if you’re trying to decide which best […]
Every time you log into a website, download software, or make an online payment, hash functions work behind the scenes to keep your data secure. These mathematical tools convert information into unique strings of characters, helping verify passwords, check file integrity, and secure digital transactions. Hash functions are crucial in modern cybersecurity, from protecting your […]
Ever signed something online and wondered if it truly holds up? A qualified certificate is what makes that signature more than just a click. It’s a digital certificate that confirms your identity and gives your electronic signature full legal power under the eIDAS regulation. That means real digital security, not just good intentions. Businesses, governments, […]
You’ve probably seen a small “Not Secure” warning sitting next to a website’s address in your browser. It might seem harmless, but it can send visitors running. That little message tells people your site isn’t safe to use, and in a world where online privacy matters, that’s a big deal. It affects trust, hurts your […]
Have you ever received an email that looked legitimate but turned out to be fraudulent? Email spoofing and phishing attacks remain persistent threats to your online security. Fortunately, new protective measures like Verified Mark Certificates (VMCs) are changing how we identify trustworthy emails. These certificates work alongside BIMI (Brand Indicators for Message Identification) to display […]
Mutual TLS (mTLS) is an authentication method that ensures secure communication between both parties in a connection. Unlike regular TLS, which verifies only the server’s identity, mTLS authenticates both client and server by exchanging and validating digital certificates. This approach forms a cornerstone of Zero Trust security frameworks, where nothing is trusted by default. Whether […]
