Hash Generator
MD5, SHA-1, SHA-256/512, SHA-3 and Keccak-256 — instantly
How it works
Type or paste text and every supported digest is computed live using the Web Crypto API (SHA family) and pure-JS implementations (MD5, SHA-3, Keccak-256). Results are shown in hexadecimal, with an uppercase toggle. Nothing is sent to a server — hashing happens entirely in your browser.
Frequently asked
Which hash algorithms are supported?
MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-512 and Keccak-256.
Is the input uploaded?
No. SHA hashes use the browser's built-in Web Crypto API and the rest are computed in JavaScript locally.
What's the difference between SHA3-256 and Keccak-256?
Keccak-256 is the original pre-standardization algorithm (used by Ethereum); SHA3-256 is the NIST-standardized variant. They produce different outputs.
