Hash Generator

Generate SHA hashes for text or files. Uses the Web Crypto API — all processing is local.

How to Generate a Hash

Enter text or upload a file, choose a hash algorithm, and click Generate Hash. The tool uses the Web Crypto API to compute the hash. All processing happens in your browser — nothing is uploaded to any server.

Algorithm Comparison

  • SHA-1 — 160-bit (40 chars). Deprecated for security. Use only for legacy compatibility.
  • SHA-256 — 256-bit (64 chars). Recommended for most use cases.
  • SHA-384 — 384-bit (96 chars). Stronger, good for high-security applications.
  • SHA-512 — 512-bit (128 chars). Strongest, but slower on 32-bit systems.
