RSA (Rivest-Shamir-Adleman) public-key cryptosystem algorithm

This is a Python RSA asymmetric cryptography algorithm uploaded on an autonomous instance of the package index (TestPyPI) deliberated for probation.

How-Tos

Precursive

Execute the venv module as a script to initiate a virtual environment:

$ python -m venv venv

Activate it:

$ source venv/Scripts/activate

Install the package:

(venv)
$ pip install -i https://test.pypi.org/simple/ rsa-pasaforte

And invoke the Python Interactive Interpreter:

(venv)
$ python

Usage or Demonstration

import it:

>>> from rsa_pasaforte import utility, main

Employ the generate_keys() function within the utility module and tuple-unpack or destructure it.

Its return value type hint is:

Tuple[Tuple[int, int], Tuple[int, int]]

>>> public_key, private_key = utility.generate_keys()

The encryption key is public and distinct from the decryption key (held undisclosed).

public_key: Tuple[int, int]
private_key: Tuple[int, int]

Initialize the plaintext variable with a string literal of your preference.

>>> plaintext = 'Python'

Toss the plaintext and public_key as arguments of the main module’s encrypt() subroutine.

ciphertext: Iterable[int]

>>> ciphertext = main.encrypt(plaintext, public_key)
>>> print(*ciphertext)
3606640 4172688 6583515 3193439 436542 872288

To crack the ciphertext, hand it over with the private_key as arguments of the decrypt() subroutine.

>>> plaintext = main.decrypt(ciphertext, private_key)
>>> print(plaintext)
