Whirlpool

Category: Hashing

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

Input / output: ArrayBuffer → string

Background: https://wikipedia.org/wiki/Whirlpool_(cryptography)

What it does

Whirlpool is a cryptographic hash function designed by Vincent Rijmen (co-creator of AES) and Paulo S. L. M. Barreto, who first described it in 2000. Several variants exist:

  • Whirlpool-0 is the original version released in 2000.

  • Whirlpool-T is the first revision, released in 2001, improving the generation of the s-box.

  • Whirlpool is the latest revision, released in 2003, fixing a flaw in the diffusion matrix.

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().

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 = ['Whirlpool', 10]
result = bake(input_value, [{"op": 'Whirlpool', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = ['Whirlpool', 10]
transform = Pipeline().then('Whirlpool', *args)
result = transform(b"example")

Direct call

pychef.ops.run_operation runs any registered operation as a plain function, under the active ExecutionPolicy (safe defaults, no network):

from pychef.ops import run_operation

args = ['Whirlpool', 10]
result = run_operation('Whirlpool', b"example", args=args)

Common operations also have typed helpers in Direct operations.

Low-level operation module

Warning

The module below is an internal implementation detail. It applies no execution policy, resource limits, or error sanitization; prefer bake(), Pipeline, or pychef.ops for application code.

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

from pychef.operations.by_operation.whirlpool import run

result = run(b"example", tuple(['Whirlpool', 10]))
pychef.operations.by_operation.whirlpool.run(value, args)

Run this operation using its shared internal implementation.

Parameters:

  • value (str | bytes)

  • args (Sequence[Any])

Return type:

str | bytes
