Bit shift left

Category: Bitwise

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

Input / output: ArrayBuffer → ArrayBuffer

Background: https://wikipedia.org/wiki/Bitwise_operation#Bit_shifts

What it does

Shifts the bits in each byte towards the left by the specified amount.

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`	Amount	`number`	`1`	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 = [1]
result = bake(input_value, [{"op": 'Bit shift left', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = [1]
transform = Pipeline().then('Bit shift left', *args)
result = transform(b"example")

Dedicated operation module

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

from pychef.operations.by_operation.bit_shift_left import run

result = run(b"example", tuple([1]))

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

Run this operation using its shared internal implementation.

Parameters:

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

Return type:

str | bytes
