How to install cryptography on Mac OS X?
My OS: Mac OS X El Capitan
When I install cryptography like this:
pip install cryptography==0.2.1
The error was:
Collecting cryptography==0.2.1
Using cached cryptography-0.2.1.tar.gz
Complete output from command python setup.py egg_info:

I am sure that I have upgrade the openssl to the newest version:
$ openssl version
OpenSSL 1.0.2f 28 Jan 2016
But I don't know how to fix it. Even I checked the official documentation:
https://cryptography.io/en/latest/installation/#building-cryptography-on-os-x
And follow that to do, the result was the same.

Trying to install the scrapy I need to install cryptography package on Mac OS El Capitan. As explained in Cryptography installation doc
env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" pip install cryptography

brew to the rescue:
brew install openssl
then brew gives a hint:
Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries
Generally there are no consequences of this for you. If you build your own software and it requires this formula, you'll need to add to your build variables:
LDFLAGS: -L/usr/local/opt/openssl/lib
CPPFLAGS: -I/usr/local/opt/openssl/include
PKG_CONFIG_PATH: /usr/local/opt/openssl/lib/pkgconfig
So just export these env vars and rerun your favorite pip install (or better to avoid havoc in future add following to your ~/.bash_profile:
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"
This worked for me like a charm!
