SSL InsecurePlatform error when using Requests package

Requests 2.6 introduced this warning for users of python prior to 2.7.9 with only stock SSL modules available.

Assuming you can't upgrade to a newer version of python, this will install more up-to-date python SSL libraries:

pip install --upgrade ndg-httpsclient 

HOWEVER, this may fail on some systems without the build-dependencies for pyOpenSSL. On debian systems, running this before the pip command above should be enough for pyOpenSSL to build:

apt-get install python-dev libffi-dev libssl-dev

I don't use this in production, just some test runners. And to reiterate the urllib3 documentation

If you know what you are doing and would like to disable this and other warnings

import requests.packages.urllib3
requests.packages.urllib3.disable_warnings()

Edit / Update:

The following should also work:

import logging
import requests

# turn down requests log verbosity
logging.getLogger('requests').setLevel(logging.CRITICAL)

Use the somewhat hidden security feature:

pip install requests[security] or pip install pyOpenSSL ndg-httpsclient pyasn1

Both commands install following extra packages:

• pyOpenSSL
• cryptography
• idna

Please note that this is not required for python-2.7.9+.

If pip install fails with errors, check whether you have required development packages for libffi, libssl and python installed in your system using distribution's package manager:

• Debian/Ubuntu - python-dev libffi-dev libssl-dev packages.

• Fedora - openssl-devel python-devel libffi-devel packages.

Distro list above is incomplete.

Workaround (see the original answer by @TomDotTom):

In case you cannot install some of the required development packages, there's also an option to disable that warning:

import requests.packages.urllib3
requests.packages.urllib3.disable_warnings()

If your pip itself is affected by InsecurePlatformWarning and cannot install anything from PyPI, it can be fixed with this step-by-step guide to deploy extra python packages manually.
