xor-cipher 5.0.2

Simple, reusable and optimized XOR ciphers in Python.

xor-cipher

Simple, reusable and optimized XOR ciphers in Python.

xor-cipher is a fast implementation of the XOR cipher written using Rust. Our tests show that it can be 1000x faster than pure Python implementations. It has been optimized to breeze through datasets of any size.

Installing

Python 3.9 or above is required.

pip

Installing the library with pip is quite simple:

$ pip install xor-cipher

Alternatively, the library can be installed from source:

$ pip install git+https://github.com/GDPSApp/xor-cipher-python.git

Or via cloning the repository:

$ git clone https://github.com/GDPSApp/xor-cipher-python.git
$ cd xor-cipher-python
$ pip install .

uv

You can add xor-cipher as a dependency with the following command:

$ uv add xor-cipher

Examples

Simple Cipher

Use the xor function to perform the simple XOR cipher:

>>> from xor_cipher import xor
>>> xor(b"Hello, world!", 0x42)
b"\n'..-nb5-0.&c"

Cyclic Cipher

Use the cyclic_xor function to perform the cyclic XOR variation:

>>> from xor_cipher import cyclic_xor
>>> cyclic_xor(b"Hello, world!", b"BLOB")
b"\n)#.-`o5->#&c"

In-Place Cipher

There are functions to perform the XOR cipher in-place, on bytearray instances:

>>> from xor_cipher import xor_in_place
>>> data = bytearray(b"Hello, world!")
>>> xor_in_place(data, 0x42)
>>> data
bytearray(b"\n'..-nb5-0.&c")
