[pyOpenSSL] Arbitrary extension to X.509 certificate

[<phi...@st...>]

Hi all,

I'd like to find out if pyOpenSSL supports the addition of arbitrary certificate extensions.  I see here that you can add extensions:

http://stackoverflow.com/questions/7279282/extract-the-value-of-a-x-509-certificate-custom-extension-using-pyopenssl

But if I try this I get:

>>> from OpenSSL import crypto
>>> ext = crypto.X509Extension('1.2.3.4', 0, 'myextension')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OpenSSL.crypto.Error: [('X509 V3 routines', 'DO_EXT_NCONF', 'unknown extension name'), ('X509 V3 routines', 'X509V3_EXT_nconf', 'error in extension')]

If it is not currently possible is there some means that the relevant OpenSSL API calls needed could be exposed through pyOpenSSL?

Thanks,
Phil
