SHA-3 & Keccak-256 Generator
Generate SHA3-224, SHA3-256, SHA3-384, SHA3-512 or Ethereum Keccak-256 hashes. Free and private: runs in your browser.
Pick a SHA-3 variant and type or paste text to get the hash.
Hashing runs locally in your browser. Your input never leaves this page.
Use cases
- Verify a download or file checksum.
- Create test fixtures for authentication code.
- Debug a hash mismatch between two systems.
Frequently asked questions
Is Keccak-256 the same as SHA3-256?
No. Ethereum uses the original Keccak padding, so its Keccak-256 output differs from the standardised SHA3-256.
Is the SHA-3 & Keccak-256 Generator free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Is hashing the same as encryption?
No. A hash is one-way: you cannot get the input back. Encryption is reversible with a key. Use slow password hashes (bcrypt, Argon2, PBKDF2) for passwords and fast hashes (SHA-256) for integrity checks.
