hi, I would like to configure TLS1.2 in my hivemq docker container . I have CA and server certificate created by me. I dont know how should I use these certificates. I have got the folowing files: **embeddedChain.crt** Server\_certificate.crt Server\_key.pem backend\_sub\_ca.crt cant figure how to use it. in your manuals ,you are talking only about jks files and creating them. what should I do if I want to use my own certificates? Thanks Tsach ---

Hi @Tsach, the simplest way to get from the OpenSSL world to the Java world, which uses the JKS format is this tool: [https://keystore-explorer.org/index.html](https://keystore-explorer.org/index.html) You should be able to import the files you created and export them again as JKS keystores. They have great documentation as well: [https://keystore-explorer.org/doc/5.4/overview.html](https://keystore-explorer.org/doc/5.4/overview.html) I wish you a great week Georg
