How to use

  1. Type or paste your input (text, JSON, anything UTF-8).
  2. Pick the algorithm — SHA-256 is the safe default.
  3. The output updates as you type. Copy with one click.

When to use which

  • SHA-256 / SHA-512 — file fingerprints, content integrity, signing.
  • SHA-1 — legacy compatibility (Git uses it for object IDs). Avoid for new systems.
  • MD5 — checksums for trusted data only. Never for security.

Privacy

SHA hashes are computed via crypto.subtle.digest. MD5 uses a pure-JavaScript implementation embedded in this page. Nothing is transmitted. Open DevTools → Network and verify: zero requests when you hash.

Frequently Asked Questions

Which hash should I use?
For new security applications, use SHA-256 or higher. SHA-1 and MD5 are still fine for non-security purposes (file fingerprints, ETags, dedupe) but are not collision-resistant.
Is MD5 secure?
No, not for security. MD5 collisions are trivially produced today. Don't use it for password storage, signatures, or anything where a forgery matters. It remains useful for checksums of trusted data.
Is anything sent to a server?
No. SHA hashes are computed via the browser's Web Crypto API; MD5 runs as pure JavaScript in your browser. Your input never leaves the page.
How long is each hash output?
MD5 = 32 hex chars (128-bit). SHA-1 = 40 (160-bit). SHA-256 = 64 (256-bit). SHA-384 = 96 (384-bit). SHA-512 = 128 (512-bit).
Are hashes case-sensitive?
We always output lowercase hex. Compare in lowercase to match other tools (e.g., `sha256sum`, `git hash-object`).
