This is a pre-production deployment of Warehouse, however changes made here WILL affect the production instance of PyPI.
Project Description

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.


pip install salsa20


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)


>>> 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())
