openssl used by Python in a MacOS

I need to download some webpages with python 3.5 in OS X El Capitan (version 10.11.5). The majority of websites connect with my application with no problem. However, there are a bunch of them that raise an exception due to OpenSSL.

I have updated OpenSSL with brew, but python continues working with the old one. Here you can see both versions present in the system:

MacBook-Air-de-Tomas:~ tomasbaviera$ openssl version
OpenSSL 1.0.2o  27 Mar 2018
MacBook-Air-de-Tomas:~ tomasbaviera$ python -c "import ssl; print ssl.OPENSSL_VERSION"  
OpenSSL 0.9.8zh 14 Jan 2016

So, it seems python does not work with the updated OpenSSL version.

Any idea to connect the new OpenSSL version with python will be greatly appreciated.

MacBook Air, OS X El Capitan (10.11.5)

brew install openssl

brew link openssl --force # if you need too

brew install python3 --with-brewed-openssl # by now, it is Python 3.6.5, and not 3.5

The binary installation of Python 3.6.5 from Python.org includes 'OpenSSL 1.0.2n 7 Dec 2017' which is still behind slightly.

You may need to adjust your local PATH:

Hello tomasbaviera,

Build your own version of Python with your required version of OpenSSL. When you rely on a package management system, then you rely on them. If you build things yourself, then you are in full control.
