Generate De Bruijn Sequence

Category: Generators

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

Input / output: string → string

Background: https://wikipedia.org/wiki/De_Bruijn_sequence

What it does

Generates rolling keycode combinations given a certain alphabet size and key length.

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`	Alphabet size (k)	`number`	`2`	A Python integer or floating-point value
`1`	Key length (n)	`number`	`3`	A Python integer or floating-point value

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 = "example"
args = [2, 3]
result = bake(input_value, [{"op": 'Generate De Bruijn Sequence', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = [2, 3]
transform = Pipeline().then('Generate De Bruijn Sequence', *args)
result = transform("example")

Dedicated operation module

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

from pychef.operations.by_operation.generate_de_bruijn_sequence import run

result = run("example", tuple([2, 3]))

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

Run this operation using its shared internal implementation.

Parameters:

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

Return type:

str | bytes
