Ascon MAC

Category: Hashing

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

Input / output: ArrayBuffer → string

Background: https://wikipedia.org/wiki/Ascon_(cipher)

What it does

Ascon-Mac produces a 128-bit (16-byte) message authentication code as part of the Ascon family standardised by NIST in SP 800-232. It provides authentication for messages using a secret key, ensuring both data integrity and authenticity. Ascon is designed for lightweight cryptography on constrained devices such as IoT sensors and embedded systems.

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 = [{'string': '', 'option': 'Hex'}]
result = bake(input_value, [{"op": 'Ascon MAC', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = [{'string': '', 'option': 'Hex'}]
transform = Pipeline().then('Ascon MAC', *args)
result = transform(b"example")

Dedicated operation module

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

from pychef.operations.by_operation.ascon_mac import run

result = run(b"example", tuple([{'string': '', 'option': 'Hex'}]))
pychef.operations.by_operation.ascon_mac.run(value, args)

Run this operation using its shared internal implementation.

Parameters:

  • value (str | bytes)

  • args (Sequence[Any])

Return type:

str | bytes
