Trust for Data-in-Motion.

Ockam is a suite of open source tools, programming libraries, and managed cloud services to orchestrate end-to-end encryption, mutual authentication, key management, credential management, and authorization policy enforcement โ€“ at massive scale.

Modern applications are distributed and have an unwieldy number of interconnections that must trustfully exchange data. To build trust for data-in-motion, applications need end-to-end guarantees of data authenticity, integrity, and confidentiality. To be private and secure by-design, applications must have granular control over every trust and access decision. Ockam allows you to add these controls and guarantees to any application.

We are passionate about making powerful cryptographic and messaging protocols simple and safe to use for millions of builders. For example, to create a mutually authenticated and end-to-end encrypted secure channel between two Ockam nodes, all you have to do is:

$ ockam secure-channel create --from /node/n1 --to /node/n2/service/api \
    | ockam message send hello --from /node/n1 --to -/service/uppercase


We handle all the underlying protocol complexity and provide secure, scalable, and reliable building blocks for your applications. In the snippet above we used Ockam Command, it's also just as easy to establish secure channels within your application code using our Rust Library.

Ockam empowers you to:

  • Create end-to-end encrypted, authenticated Secure Channels over any transport topology.
  • Provision Encrypted Relays for trustful communication within applications that are distributed across many edge, cloud and data-center private networks.
  • Tunnel legacy protocols through mutually authenticated and encrypted Portals.
  • Add-ons to bring end-to-end encryption to enterprise messaging, pub/sub and event streams.
  • Generate unique cryptographically provable Identities and store private keys in safe Vaults. Add-ons for hardware or cloud key management systems.
  • Operate project specific and scalable Credential Authorities to issue lightweight, short-lived, easy to revoke, attribute-based credentials.
  • Onboard fleets of self-sovereign application identities using Secure Enrollment Protocols to issue credentials to application clients and services.
  • Rotate and revoke keys and credentials โ€“ at scale, across fleets.
  • Define and enforce project-wide Attribute Based Access Control (ABAC) policies.
  • Add-ons to integrate with enterprise Identity Providers and Policy Providers.
  • Programming libraries for Rust, Elixir and more on the roadmap.

Get Started

Install Ockam Command

If you use Homebrew, you can install Ockam using brew.

brew install build-trust/ockam/ockam

Otherwise, you can download our latest architecture specific pre-compiled binary by running:

curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/build-trust/ockam/develop/install.sh | sh

After the binary downloads, please move it to a location in your shell's $PATH, like /usr/local/bin.

End-to-End Trustful communication using Relays.

Let's build a solution for a very common topology. A application service and an application client running in two private networks wish to communicate with each other without exposing ports on the Internet.

# Create a relay node that will relay end-to-end encrypted messages
ockam node create relay


# Start our application service, listening on a local ip and port, that clients
# would access through the cloud relay. We'll use a simple http server for our
# first example but this could be some other application service.
python3 -m http.server --bind 5000

# Setup an ockam node, called blue, as a sidecar next to our application service.
# Create a tcp outlet on the blue node to send raw tcp traffic to the application service.
# Then create a forwarder on the relay node to blue.
ockam node create blue
ockam tcp-outlet create --at /node/blue --from /service/outlet --to
ockam forwarder create blue --at /node/relay --to /node/blue


# Setup an ockam node, called green, as a sidecar next to our application client.
# Then create an end-to-end encrypted secure channel with blue, through the relay.
# Then tunnel traffic from a local tcp inlet through this end-to-end secure channel.
ockam node create green
ockam secure-channel create --from /node/green --to /node/relay/service/forward_to_blue/service/api \
  | ockam tcp-inlet create --at /node/green --from --to -/service/outlet

# Access the application service though the end-to-end encrypted, secure relay.

If something breaks or if you'd like to start from the beginning as you try this example, please run ockam reset.

In this example, we enabled two applications, a python web server and a curl web client, to communicate with each other without exposing them to the internet and without any change to their code. These two applications can run in two separate private networks and communicate with each other over a relayed, end-to-end encrypted, mutually authenticated secure channel.

Next Steps with the Rust Library

  • [Build End-to-End Encryption with Rust](./documentation/use-cases/end-to-end-encryption-with-rust#readme): In this hands-on guide, we create two small Rust programs called Alice and Bob. Alice and Bob send each other messages, over the network, via a cloud service. They mutually authenticate each other and have a cryptographic guarantee that the integrity, authenticity, and confidentiality of their messages is protected end-to-end. [๐Ÿ‘‰](./documentation/use-cases/end-to-end-encryption-with-rust#readme)

  • [Build End-to-End Encryption through Kafka](./documentation/use-cases/end-to-end-encryption-through-kafka#readme): In this guide, we show two programs called Alice and Bob. Alice and Bob send each other messages, over the network, via a cloud service, through Kafka. They mutually authenticate each other and have a cryptographic guarantee that the integrity, authenticity, and confidentiality of their messages is protected end-to-end. The Kafka instance, the intermediary cloud service and attackers on the network are not be able to see or change the contents of en-route messages. The application data in Kafka is encrypted.
