Each entity needs to have access to a private key and a certificate signed by
the diet authority.
sslEnabled default = 0
This indicates whether secure communications are enabled. Other security options
will not be taken into account if the value is 0.
sslRootCertificate default = none
This is a mandatory parameter when security is enabled. It indicates
where to find the DIET certificate which comes from the authority.
sslPrivateKey default = none
This is a mandatory parameter when security is enabled. It indicates
where to find the private key and the entity's certificate (a file containing
the concatenation of the private key and the certificate). The certificate
has to be signed by the authority with the Root Certificate.
You can find the full set of DIET configuration file options in the chapter A.
