[pyOpenSSL] Getting the next cert in hierarchy

[Sebastian Greatful]

As part of my verification I'm trying to retrieve the email embedded in the
certificate. However it returns None

 

I'm using the code below where _verify is the callback pass as the second
argument to the set_verify method of a context object.

Judging from this, http://89.150.104.27/~snot/certificate.PNG, screenshot it
seems like I need to get the second certificate in the certificate
hierarchy. but how do I access it?

 

31         def _verify(self, conn, cert, errno, depth, retcode):

 

<snip />

 

38                 print cert.get_issuer().emailAddress

 39                 self.accessRights.read = True

 40                 self.accessRights.write = True

 41                 return retcode

 

Best regards,

Seb
