Information

Our free SHA-256 Hash Generator creates cryptographic hashes from any text or file input. The SHA-256 algorithm produces a fixed-size 256-bit (32-byte) hash represented as a 64-character hexadecimal string. Widely used in blockchain technology, digital signatures, password storage, and file integrity verification, SHA-256 offers significantly stronger security than older algorithms like MD5. This online tool processes everything locally in your browser - your data never leaves your device. Simply enter text or upload a file to instantly generate a secure SHA-256 hash for verification purposes or security implementations.

How to Use

  1. Enter text or upload a file to hash
  2. The SHA-256 hash will be generated automatically
  3. Copy the hash to verify data integrity elsewhere

Note: All processing happens locally in your browser. Your data never leaves your device, ensuring complete security and privacy.
