Description: python-salsa20
        ==============
        
        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
