What is SHA-256?

SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a 64-character hexadecimal string. It's widely used in security applications, blockchain, and data integrity verification.

Open Source & Secure

This tool uses the Web Crypto API, a built-in browser API that implements FIPS-validated cryptographic algorithms. No external dependencies, no tracking, completely open source.

Use Cases

SHA-256 is used for password hashing, file integrity verification, digital signatures, blockchain transactions, and SSL/TLS certificates. It's considered secure for cryptographic applications.

Browser-Based Processing

All processing happens locally in your browser using the Web Crypto API. Your input is never transmitted to any server, ensuring complete privacy and offline functionality.
