A small and insanely fast ARCFOUR (RC4) cipher implementation of Python.
Strongly focused on performance; entire source code is written in C.
Thread-safety; you can improve further performance with multi-threading.
Easily installable; single file with no dependency, pre-built wheels provided.
Benchmark
Below is benchmark metrics against 3 major RC4 implementations.
The whole benchmark code is in ./benchmark.py.
Install
Install from PyPI
pip install arc4Or clone the repo and do install
git clone https://github.com/manicmaniac/arc4.git
cd arc4
python setup.py installUsage
>>> from arc4 import ARC4
>>> arc4 = ARC4(b'key')
>>> cipher = arc4.encrypt(b'some plain text to encrypt')Because RC4 is a stream cipher, you must initialize RC4 object in the beginning of each operations.
>>> arc4 = ARC4(b'key')
>>> arc4.decrypt(cipher)
b'some plain text to encrypt'Documents
Here is the API reference.
