DistGuard (v0.0.1 - Pre-Alpha)

This package is under active development. Check the repository at DistGuard for development progress.

---

Vision

By default, Elixir node communication is unencrypted. DistGuard secures Elixir/Erlang node communication by automating the creation of a private, project-specific Certificate Authority (CA). Through a set of simple Mix tasks, it configures your release to use mutual TLS for all inter-node traffic, adopting a zero-trust security model by default.

DistGuard is for internal node security only. It is not a replacement for public CAs like Let's Encrypt and should not be used for client-facing HTTPS traffic.

Planned Features

• A mix dist_guard.init task for one-command project setup.
• Automatic generation of a secure openssl.cnf and management of keys/certificates.
• A Config.Provider for seamless integration with mix release.
• High-performance, secure-by-default TLS 1.3 configurations.

Prerequisites

• Erlang/OTP 28.0.1+: This package will only support modern OTP versions.
• OpenSSL 3.0.0+: DistGuard will use the openssl command-line tool.

Installation (Future)

Once a stable version is released, you will be able to install the package by adding dist_guard to your list of dependencies in mix.exs:

def deps do
  [
    {:dist_guard, "~> 0.1.0"}
  ]
end
