🔐 What is SHA-256? | How This Powerful 🔢 Hash Function Keeps Your Data Secure! 🛡️#sha256 #crypto

In this video, we dive deep into SHA-256, the 256-bit cryptographic hash function designed by the U.S. National Security Agency (NSA). Learn how this powerful hash algorithm keeps your data secure, protecting everything from Bitcoin mining to online transactions. SHA-256 is a key part of modern cryptography and is widely used in blockchain technology, digital signatures, and securing sensitive information. But how does it work? In simple terms, we explain how it takes an input and outputs a fixed-length, unique "hash"—a fundamental process for cybersecurity and data encryption.
