Keccak

The Keccak hash algorithm was designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche, building upon RadioGatún. It was selected as the winner of the SHA-3 design competition. This version of the algorithm is Keccak[c=2d] and differs from the SHA-3 specification. Keccak lives in the Hashing category of the fx menu.

Parameters

Parameter	Type	Required	Default	Description
Input	string	yes	—	Value to transform. Previous step output or a literal.
Size	string	no	512	Choose one of: 512, 384, 256, 224.

Input is the primary value (previous step output or a literal).

Returned value

Type	Description
string	Result of the Keccak transformation.

Limitations

• This operation treats Input as raw bytes (binary-capable). Non-text payloads may display differently after decoding.

Example

Run Keccak

The Keccak hash algorithm was designed by Guido Bertoni, Joan Daemen, Michaël Peeters, and Gilles Van Assche, building upon RadioGatún. Adjust optional parameters when the defaults do not match your payload.

1. Set Input to the value to transform (previous step output or a literal).

2. Review Size and keep defaults unless your format requires otherwise.

3. Confirm Output value shows the transformed result.
