What is a Hash?

A Hash Generator computes cryptographic hash digests (MD5, SHA-1, SHA-256, SHA-512) from text or files. Hashes are one-way fingerprints used to verify data integrity, check file downloads, store passwords securely, and detect tampering. This tool runs entirely in your browser using the WebCrypto API for maximum speed and security.

How to Use This Tool

  1. Type or paste text into the input area to generate hashes instantly.
  2. Or click Load File to hash any file from your computer.
  3. All four hash algorithms compute simultaneously in real time.
  4. Enable Compare Mode to verify a hash against generated results.
  5. Copy individual hashes or download all results as a text file.
