Comment:

 lgtm - but I didn't test it, but it should be a safe substitution:
 {{{

     urandom(...)
         urandom(n) -> str

         Return n random bytes suitable for cryptographic use.
 }}}
 https://github.com/pyca/pyopenssl/blob/16.2.0/src/OpenSSL/rand.py#L41
 {{{
 def bytes(num_bytes):
     """
     Get some random bytes from the PRNG as a string.
     This is a wrapper for the C function ``RAND_bytes``.
     :param num_bytes: The number of bytes to fetch.
     :return: A string of random bytes.
     """
 }}}
