# Encrypting Zenoh Traffic

## Make the CA and Certs

Use the tools we have for that!

git.jpace121.net:2222/public/j7s-ca

```
j7s_mk_ca --org-name test -o ca
j7s_mk_cert --common-name test-node --identity-type domain --identity node.test.internal.jpace121.net --auth-mode server --ca-path ./ca/ -o cert
```

## Change the configs

Note: Can also TLS instead of quic. I tried both, and just saved the last one.

Inspect the traffic in wireshark!
