Hashes

Type or paste any text and get its hash in eight algorithms at once: MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-512 and Keccak-256. Everything is computed locally in your browser.

How to use

  1. Type or paste the text
  2. Hashes for all algorithms update as you type
  3. Copy the one you need with a click

Frequently asked questions

Is my text sent to a server?

No. Hashes are computed locally via the browser's Web Crypto API and pure JS — your input never leaves the page.

Can I "decrypt" an MD5 or SHA-256 hash?

No. Hashes are one-way functions; the only way back is guessing inputs. That's exactly why passwords are stored as hashes.

Which algorithm should I use?

For integrity checks SHA-256 is the safe default. MD5 and SHA-1 are broken for security purposes — use them only for legacy compatibility.

Why does Ethereum use Keccak-256?

Keccak-256 is the original SHA-3 submission adopted by Ethereum before the final NIST standard; this tool provides both variants.
