[Cryptography-dev] Cipher/tls cipher negotiated

[Karan karan]

Thanks for the prompt reply *Alex !*

I have sent my question to the requests mailing list. I'm using the pythons
native ssl library not the pyOpenSSL libary as i can use the ssl's library
context in the Adapter. I looked into the requests response object but
could'nt find a way to the ciphers from it.

I wanted to use the requests package as it provides a higher level library
to call into the get,post calls. But i'm not sure how i can interface the
OpenSSL Context with the requests, do you know if there is any way i could
do that.

Thanks,
Konteya.
