About SHA
Compute SHA‑1, SHA‑256 or SHA‑512 hashes for text. For quick MD5 comparisons, see the MD5 Hash tool. If inputs are URL/Base64 encoded, decode via the URL Encoder/Decoder or Base64 Encoder/Decoder and then inspect with JSON Formatter.
Runs locally in your browser using the Web Crypto API. For password generation use the Password Generator and store using modern salted algorithms.
Common Use Cases
- Verify data integrity
- Check file hashes
- Prepare inputs for signatures
How It Works
- Choose SHA‑1 / SHA‑256 / SHA‑512
- Handles UTF‑8 via TextEncoder
- One‑click copy of results
- No data uploaded
FAQ
Is SHA reversible?
No. SHA is a one‑way hash (like MD5).
Which algorithm should I use?
Prefer SHA‑256 or SHA‑512 for stronger security; for legacy checks compare with MD5 as needed.
Does it work offline?
Yes, it runs entirely in your browser and no data is uploaded.
