In this hands-on example we send end-to-end encrypted messages through Redpanda.

Ockam encrypts messages from a Producer all-of-the-way to a specific Consumer. Only that specific Consumer can decrypt these messages. This guarantees that your data cannot be observed or tampered with as it passes through Redpanda or the network where it is hosted. The operators of Redpanda can only see encrypted data in the network and in service that they operate. Thus, a compromise of the operator's infrastructure will not compromise the data stream's security, privacy, or integrity.

To learn how end-to-end trust is established, please read: “How does Ockam work?


This example requires Bash, Git, Curl, Docker, and Docker Compose. Please set up these tools for your operating system, then run the following commands:

# Clone the Ockam repo from Github.
git clone --depth 1 && cd ockam

# Navigate to this example’s directory.
cd examples/command/portals/kafka/redpanda/docker/

# Run the example, use Ctrl-C to exit at any point.

If everything runs as expected, you'll see the message: The example run was successful 🥳


The script, that you ran above, and its accompanying files are full of comments and meant to be read. The example setup is only a few simple steps, so please take some time to read and explore.


  • The script calls the run function which invokes the enroll command to create an new identity, sign in to Ockam Orchestrator, set up a new Ockam project, make you the administrator of this project, and get a project membership credential.

  • The run function then generates three new enrollment tickets, each valid for 10 minutes, and can be redeemed only once. The first ticket is meant for the Ockam node that will run in Redpanda Operator’s network. The second and third tickets are meant for the Consumer and Producer, in the Ockam node that will run in Application Team’s network.

  • In a typical production setup, an administrator or provisioning pipeline generates enrollment tickets and gives them to nodes that are being provisioned. In our example, the run function is acting on your behalf as the administrator of the Ockam project. It provisions Ockam nodes in Redpanda Operator’s network and Application Team’s network, passing them their tickets using environment variables.

  • The run function takes the enrollment tickets, sets them as the value of an environment variable, and invokes docker-compose to create Redpanda Operator’s and Application Teams’s networks.

Application Teams

We sent end-to-end encrypted messages through Redpanda.

Messages are encrypted with strong forward secrecy as soon as they leave a Producer, and only the intended Consumer can decrypt those messages. Redpanda and other Consumers can only see encrypted messages.

All communication is mutually authenticated and authorized. Keys and credentials are automatically rotated. Access can be easily revoked.
