Bindings for the NaCL implementation of Salsa20 and XSalsa20 by D. J. Bernstein (taken from libsodium).
Compatible with Python 2.6, 2.7 and 3.3.
The library performs a self-test at each import.
Installation
pip install salsa20
Usage
def Salsa20_keystream(length, nonce, key) def Salsa20_xor(message, nonce, key) def XSalsa20_keystream(length, nonce, key) def XSalsa20_xor(message, nonce, key)
Use [X]Salsa20_keystream to generate a keystream of the desired length, or pass [X]Salsa20_xor a plaintext or a ciphertext to have it XOR’d with the keystream.
Being a stream cipher, [X]Salsa20_xor does both encryption and decryption.
All values must be binary strings (str on Python 2, bytes on Python 3)
Example
>>> from salsa20 import XSalsa20_xor >>> from os import urandom >>> IV = urandom(24) >>> KEY = b'*secret**secret**secret**secret*' >>> ciphertext = XSalsa20_xor(b"IT'S A YELLOW SUBMARINE", IV, KEY) >>> print(XSalsa20_xor(ciphertext, IV, KEY).decode()) IT'S A YELLOW SUBMARINE
