To Modhex

Category: Encoding

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

Input / output: ArrayBuffer → string

Background: https://en.wikipedia.org/wiki/YubiKey#ModHex

What it does

Converts the input string to modhex bytes separated by the specified delimiter.

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`	Delimiter	`option`	`'Space'`	`'Space'`, `'Percent'`, `'Comma'`, `'Semi-colon'`, `'Colon'`, `'Line feed'`, `'CRLF'`, `'None'`
`1`	Bytes per line	`number`	`0`	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 = b"example"
args = ['Space', 0]
result = bake(input_value, [{"op": 'To Modhex', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = ['Space', 0]
transform = Pipeline().then('To Modhex', *args)
result = transform(b"example")

Dedicated operation module

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

from pychef.operations.by_operation.to_modhex import run

result = run(b"example", tuple(['Space', 0]))

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

Run this operation using its shared internal implementation.

Parameters:

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

Return type:

str | bytes
