RSA Encrypt

Category: Public Key

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

Input / output: string → string

Background: https://wikipedia.org/wiki/RSA_(cryptosystem)

What it does

Encrypt a message with a PEM encoded RSA public key.

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`	RSA Public Key (PEM)	`text`	`'-----BEGIN RSA PUBLIC KEY-----'`	`'-----BEGIN RSA PUBLIC KEY-----'`
`1`	Encryption Scheme	`argSelector`	`'RSA-OAEP'`	`'RSA-OAEP'`, `'RSAES-PKCS1-V1_5'`, `'RAW'`
`2`	Message Digest Algorithm	`option`	`'SHA-1'`	`'SHA-1'`, `'MD5'`, `'SHA-256'`, `'SHA-384'`, `'SHA-512'`

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 = ['-----BEGIN RSA PUBLIC KEY-----', 'RSA-OAEP', 'SHA-1']
result = bake(input_value, [{"op": 'RSA Encrypt', "args": args}])
print(result)

Pipeline example

from pychef import Pipeline

args = ['-----BEGIN RSA PUBLIC KEY-----', 'RSA-OAEP', 'SHA-1']
transform = Pipeline().then('RSA Encrypt', *args)
result = transform("example")

Dedicated operation module

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

from pychef.operations.by_operation.rsa_encrypt import run

result = run("example", tuple(['-----BEGIN RSA PUBLIC KEY-----', 'RSA-OAEP', 'SHA-1']))

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

Run this operation using its shared internal implementation.

Parameters:

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

Return type:

str | bytes
