Note: MD5 isn’t available in the browser’s crypto API; SHA-256+ are recommended anyway.
How it works
Type text and get its SHA-1, SHA-256, SHA-384 and SHA-512 hashes instantly.
All hashing happens on your device.
Frequently asked questions
- Is my text uploaded?
- No — hashes are computed locally with the browser’s Web Crypto API.
- Why no MD5?
- Browsers don’t expose MD5 (it’s insecure). SHA-256 or stronger is recommended for checksums.
