You need to have private key and CA signed certificate (to test you may generate your own Self signed
certificate) to configure your nginx to serve request over SSL. Add following lines into your nginx.conf file and make required changes to point ssl_certificate to location of your certificate in this configuration it is server.crt (if you copy your .crt and .key file into <nginx home>/conf folder . In that case you can specify only file name other wise you need to specify absolute path of a file). Change ssl_certificate_key to point your key file. Restart nginx server and hit https url https://yourdomain.com. ( If you have installed self signed certificate you will see Untrusted Exception. You can safely continue with it.)
