openssl/aes.h' file not found on Mac

I'm trying to install a python implementation of a proxy re-encryption scheme I found here.

When running $ sudo python setup.py install I get back an error

fatal error: 'openssl/aes.h' file not found

There are a few questions like this around (this or this (not for mac)) but none of the answers there fixed my problem.

I've tried (all taken from answers I found):

  1. Running env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" pip install cryptography and trying again;
  2. brew install openssl and trying again;
  3. brew reinstall python and trying again;

Option 1. returned

I'm running OSX 10.12.6.

Any ideas?

Specifying environment variables solved the issue for me:

For MacOS users:

Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries. This means that you will need to export some OpenSSL settings yourself.

Use the following commands:

export CFLAGS="-I$(brew --prefix openssl)/include"
export LDFLAGS="-L$(brew --prefix openssl)/lib"

First check if the path pointed out by $(brew --prefix openssl)/include exists.

If above is fine, you can try 

$ cd /usr/local/include
$ ln -s ../opt/openssl/include/openssl .
