Create Self Signed SSL Certificate

You can do this via openssl:

1. Install openssl package (if you are using Windows, download binaries here).
2. Generate private key: openssl genrsa 2048 > private.pem
3. Generate the self signed certificate: openssl req -x509 -days 1000 -new -key private.pem -out public.pem
4. If needed, create PFX: openssl pkcs12 -export -in public.pem -inkey private.pem -out mycert.pfx

Note: Use Windows command prompt.
