DES Encrypt

Category: Ciphers

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

Input / output: string → string

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

What it does

DES is a previously dominant algorithm for encryption, and was published as an official U.S. Federal Information Processing Standard (FIPS). It is now considered to be insecure due to its small key size. Key: DES uses a key length of 8 bytes (64 bits). You can generate a password-based key using one of the KDF operations. IV: The Initialization Vector should be 8 bytes long. If not entered, it will default to 8 null bytes. Padding: In CBC and ECB mode, PKCS#7 padding will be used.

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`	Key	`toggleString`	`{'string': '', 'option': 'Hex'}`	`''`
`1`	IV	`toggleString`	`{'string': '', 'option': 'Hex'}`	`''`
`2`	Mode	`option`	`'CBC'`	`'CBC'`, `'CFB'`, `'OFB'`, `'CTR'`, `'ECB'`
`3`	Input	`option`	`'Raw'`	`'Raw'`, `'Hex'`
`4`	Output	`option`	`'Hex'`	`'Hex'`, `'Raw'`

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 = [{'string': '', 'option': 'Hex'}, {'string': '', 'option': 'Hex'}, 'CBC', 'Raw', 'Hex']
result = bake(input_value, [{"op": 'DES Encrypt', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = [{'string': '', 'option': 'Hex'}, {'string': '', 'option': 'Hex'}, 'CBC', 'Raw', 'Hex']
transform = Pipeline().then('DES Encrypt', *args)
result = transform("example")

Direct call

pychef.ops.run_operation runs any registered operation as a plain function, under the active ExecutionPolicy (safe defaults, no network):

from pychef.ops import run_operation

args = [{'string': '', 'option': 'Hex'}, {'string': '', 'option': 'Hex'}, 'CBC', 'Raw', 'Hex']
result = run_operation('DES Encrypt', "example", args=args)

Common operations also have typed helpers in Direct operations.

Low-level operation module

Warning

The module below is an internal implementation detail. It applies no execution policy, resource limits, or error sanitization; prefer bake(), Pipeline, or pychef.ops for application code.

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

from pychef.operations.by_operation.des_encrypt import run

result = run("example", tuple([{'string': '', 'option': 'Hex'}, {'string': '', 'option': 'Hex'}, 'CBC', 'Raw', 'Hex']))

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

Run this operation using its shared internal implementation.

Parameters:

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

Return type:

str | bytes
