One-Time Pad Cipher: The Only Mathematically Unbreakable Encryption Method Here’s the deal—most encryption methods can be cracked with enough time and computing power. But One-Time Pad (OTP) cipher is different. It’s the only mathematically proven unbreakable encryption in existence. In this guide, we’ll break down: ✔ How OTP works (with a step-by-step example) ✔ Why […]

Data Encryption Standard (DES): How It Works, Security Flaws & Modern Alternatives Data Encryption Standard (DES): How It Works, Security Flaws & Modern Alternatives The Data Encryption Standard (DES) is a symmetric-key block cipher that shaped modern cryptography when adopted by NIST in 1977. It was once widely used for securing sensitive data, but with […]

Images come in many formats like JPEG, PNG, WebP, BMP, and GIF. Sometimes, you need to change an image’s format – for example, converting a JPEG to a PNG or a WebP to a JPEG. Whether it’s for web optimization, transparent backgrounds, or better quality, image conversion is simple if you know the right tools. […]
