Create a self signed certificate with OpenSSL on Windows

First unzip OpenSSL from and put it anywhere you want e.g. c:\openssl.

Right click on c:\openssl\bin\openssl.exe and "run as administrator".

Enter the following command where c:\openssl is the location you unzipped into:

> req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem -config "C:\OpenSSL\openssl.cnf"

Country name or any of the other information isnt required so you can keep pressing enter. You should now have two files in the bin folder key.pem and cert.pem.
