Hash Generator
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes of any text.
Hashing is computed locally using your browser's Web Crypto API — nothing you type here leaves your device.
Frequently asked questions
Which hash should I use?+
For anything security-related (passwords, signatures, integrity checks against tampering), use SHA-256 or higher — MD5 and SHA-1 are both cryptographically broken and shouldn't be trusted for security purposes. They're included here because they're still common for non-security uses like checksums and cache keys.
Does the hash update as I type?+
Yes — every algorithm recomputes live as you edit the text, no button to click.
Is my text sent anywhere to be hashed?+
No — SHA hashes are computed with your browser's built-in Web Crypto API, and MD5 with a small local library. Nothing leaves your device.
