Python library nonce generation is insecure #241

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The Python library nonce generation uses the following code:

    return ''.join([str(random.randint(0, 9)) for i in range(length)])

This is not terribly secure, as it relies on a non cryptographically secure 
PRNG with an unknown seed.

Instead, nonce generation should be something like this:

    return os.urandom(8).encode('base64'))
