TWINE: A Lightweight Block Cipher for Multiple Platforms

This repository is an implementation of TWINE: A Lightweight Block Cipher for Multiple Platforms paper introduced by Tomoyasu Suzaki, Kazuhiko Minematsu, Sumio Morioka, and Eita Kobayashi.

Installation

Install by pip from PyPI:

pip3 install twine

Or install latest version from github:

python3 -m pip install -U git+https://github.com/amoallim15/TWINE.git

Usage

This repository contains a command line tool that can be used to ecnrypt plaintext samples using either of the supported 80 bits or 128 bits sized keys.

Example 1:

xtwine "hello world" -k "<o8~I{?3Uz"

The output:

Encryption Key: "<o8~I{?3Uz"
abb90d4c0a8f67632cec7c01ee409ea1

Example 2:

xtwine "01bbed92bccc2104b7e12141f1413ad6" -d -k "4ejqxfDL3#"

The output:

Decryption Key: "4ejqxfDL3#"
hello world

Example 3:

xtwine "1 plus 1 equals 2"

The output:

Encryption Key: "8_D]H[!^M*"
0315a70682ac625cdced6a7ff834d629c2b70de4e2d1fc7b

Example 4:

xtwine "1 plus 1 equals 2" -z 128

The output:

Encryption Key: "oti,D:H6[5WX|8jS"
7f9c4394decc4c59c94be30b49db5ef66943a2938416382f

Example 5:

    from xtwine import Twine

    twine = Twine(key_size=0x50)
    # If the key param is not specified
    # it will generate a key automatically.
    ciphertext = twine.encrypt("hello world")
    print(ciphertext) # > "abb90d4c0a8f67632cec7c01ee409ea1"
    plaintext = twine.decrypt(ciphertext)
    print(plaintext) # > "hello world"
