DTR uses SSL certificates in addition to a login/password to login. 

The steps to use openssl to create a self-signed certificate as below:

1. First create a private key (myserver.key) and a certificate signing request (server.csr)
openssl req -nodes -newkey rsa:2048 -keyout myserver.key -out server.csr

2. Finally create the SSL certificate (server.crt) using the csr and private key just created:
openssl x509 -req -days 365 -in server.csr -signkey myserver.key -out server.crt
