SHA3

Category: Hashing

Status: Registered and callable in the CyberChef 11.3.0 compatibility inventory.

Input / output: ArrayBuffer → string

Background: https://wikipedia.org/wiki/SHA-3

What it does

The SHA-3 (Secure Hash Algorithm 3) hash functions were released by NIST on August 5, 2015. Although part of the same series of standards, SHA-3 is internally quite different from the MD5-like structure of SHA-1 and SHA-2. SHA-3 is a subset of the broader cryptographic primitive family Keccak designed by Guido Bertoni, Joan Daemen, Michaxebl Peeters, and Gilles Van Assche, building upon RadioGatxfan.

Note

Status here means the operation name is implemented and callable. It does not by itself promise byte-for-byte parity for every upstream option. See Compatibility and current status for the verified scope and known boundaries.

Arguments and options

Arguments are positional. Keep their order when using bake() or Pipeline.then().

Index	Name	UI type	PyChef default	Accepted values / format
`0`	Size	`option`	`'512'`	`'512'`, `'384'`, `'256'`, `'224'`

Recipe template

Important

This is a call template built from the documented defaults. Replace placeholder values such as empty keys, paths, patterns, or lookup data before running it.

from pychef import bake

input_value = b"example"
args = ['512']
result = bake(input_value, [{"op": 'SHA3', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = ['512']
transform = Pipeline().then('SHA3', *args)
result = transform(b"example")

Dedicated operation module

The registered entry point lives in pychef.operations.by_operation.sha3. Direct calls receive the input value and a positional argument tuple:

from pychef.operations.by_operation.sha3 import run

result = run(b"example", tuple(['512']))

pychef.operations.by_operation.sha3.run(value, args)

Run this operation using its shared internal implementation.

Parameters:

value (str | bytes)
args (Sequence[Any])

Return type:

str | bytes
