[Cryptography-dev] help: pica cryptography get subjectAltNames

[Glyph Lefkowitz]

Does pyOpenSSL have this functionality built in?  My understanding is that it doesn't, which is why <https://pypi.python.org/pypi/service_identity> uses pyasn1 for ASN.1 extension parsing.  (By the way, you probably just want to use the service_identity module unless you're doing something truly unusual with SANs ;-)).
