What is a hash generator?

A hash generator creates deterministic fingerprints (checksums) for any input. Use it to verify downloads, detect changes, and compare text or files. Everything runs locally in your browser; nothing is uploaded.

Supported algorithms

  • SHA-256: recommended default for integrity checks.
  • SHA-384 / SHA-512: longer digests for higher collision resistance.
  • SHA-1: legacy; avoid for security-sensitive use.

How to use

  1. Select text or file input, then paste text or upload a file.
  2. Pick an algorithm and (optionally) uppercase output in Settings.
  3. Copy the hex result to share or compare.

Best practices

  • Publish expected hashes alongside downloads so users can verify integrity.
  • Keep casing consistent when comparing hex outputs.
  • For passwords or secrets, use a slow, salted KDF (bcrypt, scrypt, Argon2) instead of plain hashes.
