Keccak 256 Hash

Generate Keccak hash with 256 bit length from your text or file.

Keccak 256 bit Hash Generator

This is the original Keccak algorithm, if you want SHA3, you can check SHA3-224, SHA3-256, SHA3-384, or SHA3-512.

Keccak is the winner of SHA-3 competition, so many people referring SHA-3 as Keccak. The core algorithm is still the same, but there's slight modification for SHA-3. That's why when we compared the result of SHA-3 with Keccak result, it will be different.

Fun fact: if you try to learn keccak algorithm, you may encounter word absorb and squeeze which related with Sponge.

Keccak use Sponge construction, not Merke-Damgård construction which used on MD4, MD5, RIPE-MD, RIPE-MD160, SHA0, SHA1, SHA2.
