Setting up SSL on Ubuntu 16.04

The steps to set up SSL on Ubuntu 16.04 are as follows:

First, create a private key and self-signed certificate request (Note: This is only for testing purposes)

openssl req \
  -x509 -sha256 -nodes -days 365 -subj "/CN=eventstore.org" \
  -newkey rsa:2048 -keyout geteventstore.pem -out geteventstore.csr

Export a p12 file from the certificate request. This will be used when starting Event Store :

openssl pkcs12 -export -inkey geteventstore.pem -in geteventstore.csr -out geteventstore.p12

The certificate needs to be added to Ubuntu’s trusted certificates. Copy the cert to the ca-certificates folder and update the certificates :

sudo cp geteventstore.csr /usr/local/share/ca-certificates/geteventstore.crt

sudo update-ca-certificates

Mono has its own separate certificate store which needs to be synced with the changes we have made to Ubuntu’s certificates. You will need to install mono-devel :

sudo apt-get install mono-devel

This installs cert-sync, which can be used to update mono’s certificate store with the new certificate :

sudo cert-sync geteventstore.csr

Start Event Store with the following configuration :

CertificateFile: geteventstore.p12
ExtSecureTcpPort: 1115

Connect to Event Store using the Event Store .NET Client.

var settings = ConnectionSettings.Create().UseSslConnection("eventstore.org", true);

using (var conn = EventStoreConnection.Create(settings, new IPEndPoint(IPAddress.Loopback, 1115)))
