AES-128

This tool provides encryption/decrytion according to AES(128) standart. The standart is based on symmetric Rijndael algorithm and regulates work with 128/192/256 bit long keys. My tool works only with 128 bit length key, ie your secret key should be less than 16 symbols. The algorithm has been recognized impregnable even with this key-length.

About this fork

The main goal of the fork is to make it simple to use, without adding third-party libraries, and also to adapt the functioning of the project in the environment of a modern version of Python

FIXED AND UPGRADED by Mr. JS (October 2023)

Requirements

Pure Python 3.11 (No third party libraries are used)

How to install

There is only one file:

aes.py

Simple put him in your project (no need to install third-party libraries).

How to use

Now it's simple after my upgrade of this project:

from aes import run, Direction

pwd='1234567890'
data_source = 'This is a text string'
data_encrypted = run(Direction.ENCRYPT, data_source, pwd)
data_decrypted = run(Direction.DECRYPT, data_encrypted, pwd)
print(f'SOURCE:\n{data_source}\nSTORAGE (source=>encrypted):\n{data_encrypted}\nRESULT (source=>encrypted=>decrypted):\n{data_decrypted}')

Results:

SOURCE:
This is a text string
STORAGE (source=>encrypted):
[228, 65, 17, 225, 113, 34, 220, 249, 40, 93, 247, 195, 208, 93, 228, 140, 64, 231, 122, 38, 98, 186, 82, 229, 87, 122, 167, 242, 46, 67, 27, 86]
RESULT (source=>encrypted=>decrypted):
This is a text string

Now it works in Python 3.11 environment

Notes

If you want to save/load encrypted data in/from file you may use "bytearray" (see example here):

from aes import run, Direction
import os

def decode(filename, pwd=''):
    data = ''
    if os.path.isfile(filename):
        with codecs.open(filename, 'rb') as f:
            data = bytes(f.read())
            data = run(Direction.DECRYPT, data, pwd)
    return data

def encode(filename, data='', pwd=''):
    if os.path.isfile(filename):
        with open(filename, 'wb') as f:
            data = run(Direction.ENCRYPT, data, pwd)
            f.write(bytearray(data))
    return data
