SHA-3 Hash Generator
Hash text or files with SHA-3 (FIPS 202) and choose a 224, 256, 384 or 512-bit output. Note that this is not the same as Ethereum's Keccak-256.
How to use it
Pick the output length, then type text or choose a file. SHA3-256 is the most common choice and matches openssl dgst -sha3-256.
