OPENSSL_CONF fix for NPM (nodejs)

Source: https://stackoverflow.com/questions/42918916/npm-install-openssl-failed-on-windows-10

As mentionned by Royi Mindel the npm openssl package is just a wrapper around the openssl binaries and not the actual openssl. You need to install openssl on your Windows 10 machine as follows:

1) Download the binaries from https://code.google.com/archive/p/openssl-for-windows/downloads
2) Extract to C:\OpenSSL-Win32\ (or whatever name you want to give it).
3) Add the system environment variable OPENSSL_CONF with value c:\OpenSSL-Win32\openssl.cnf (points to the config file where you extrated the binaries)
4) Add C:\OpenSSL-Win32\bin to your Path environment variable
5) Open a cmd or PowerShell and type openssl version. It should work and you should see the version installed
