<p>A customer asked me how they can store a JKS file with certificates in a spring cloud config server, retrieve it on application startup and use it to setup a a Java SSLContext for doing mutual TLS with a backend system, that was using self signed certificates.</p>
<p>The config server can’t store binary files, so you have to first encode the JKS file as a base64 string, put in the config server then pull it at startup with regular Spring <a href="https://hashnode.com/@Value" class="user-mention" target="_blank" rel="noopener">@Value</a> annotation which is then used to setup the context. I created a sample application which you can find at <a target="_blank" href="https://github.com/asaikali/mtls-demo">https://github.com/asaikali/mtls-demo</a></p>
