This indicates that the "cryptography" version does not fit with your "openssl" version: "openssl" defines "SSLv3_method" as a function returning a constant pointer to an "SSL_METHOD", while "cryptography" defines it as a pointer to such a function. I would contact the "cryptography" author. -- https://mail.python.org/mailman/listinfo/python-list
