BLAKE2b

Category: Hashing

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

Input / output: ArrayBuffer → string

Background: https://wikipedia.org/wiki/BLAKE_(hash_function)#BLAKE2b_algorithm

What it does

Performs BLAKE2b hashing on the input. BLAKE2b is a flavour of the BLAKE cryptographic hash function that is optimized for 64-bit platforms and produces digests of any size between 1 and 64 bytes. Supports the use of an optional key.

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'`, `'160'`, `'128'`
`1`	Output Encoding	`option`	`'Hex'`	`'Hex'`, `'Base64'`, `'Raw'`
`2`	Key	`toggleString`	`{'string': '', 'option': 'UTF8'}`	`''`

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', 'Hex', {'string': '', 'option': 'UTF8'}]
result = bake(input_value, [{"op": 'BLAKE2b', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = ['512', 'Hex', {'string': '', 'option': 'UTF8'}]
transform = Pipeline().then('BLAKE2b', *args)
result = transform(b"example")

Dedicated operation module

The registered entry point lives in pychef.operations.by_operation.blake2b. Direct calls receive the input value and a positional argument tuple:

from pychef.operations.by_operation.blake2b import run

result = run(b"example", tuple(['512', 'Hex', {'string': '', 'option': 'UTF8'}]))

pychef.operations.by_operation.blake2b.run(value, args)

Run this operation using its shared internal implementation.

Parameters:

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

Return type:

str | bytes
