Cannot sign (or, presumably, verify) data with embedded NULs

[Jean-Paul Calderone]

>>> OpenSSL.crypto.sign(key, b'\0', 'md5')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: must be bytes without null bytes, not bytes

I've pushed bugfix into lp:~lihalla/pyopenssl/sign_and_verify - the commit message should be self-explanatory.

Thanks very much for the fix, David!
