From Base45

Category: Encoding

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

Input / output: string → byteArray

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

What it does

Base45 is a notation for encoding arbitrary byte data using a restricted set of symbols that can be conveniently used by humans and processed by computers. The high number base results in shorter strings than with the decimal or hexadecimal system. Base45 is optimized for usage with QR codes.

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	`string`	`'0-9A-Z $%*+\\-./:'`	`'0-9A-Z $%*+\\-./:'`
`1`	Remove non-alphabet chars	`boolean`	`True`	`True` or `False`

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 = ['0-9A-Z $%*+\\-./:', True]
result = bake(input_value, [{"op": 'From Base45', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = ['0-9A-Z $%*+\\-./:', True]
transform = Pipeline().then('From Base45', *args)
result = transform("example")

Dedicated operation module

The registered entry point lives in pychef.operations.by_operation.from_base45. Direct calls receive the input value and a positional argument tuple:

from pychef.operations.by_operation.from_base45 import run

result = run("example", tuple(['0-9A-Z $%*+\\-./:', True]))

pychef.operations.by_operation.from_base45.run(value, args)

Run this operation using its shared internal implementation.

Parameters:

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

Return type:

str | bytes
