🛡️ What is SHA-256 Hash?

SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a 256-bit hash value, expressed as a 64-character hexadecimal number. It's part of the SHA-2 family and is currently the gold standard for cryptographic hashing, used in Bitcoin, SSL certificates, and modern security applications.

📋 How to Use This SHA-256 Generator:
