AppIdentity for Elixir

Description

AppIdentity is an Elixir implementation of the Kinetic Commerce application identity proof algorithm as described in its spec.

Synopsis

app = %{id: id, secret: secret, version: 2}
proof = AppIdentity.generate_proof(app)
AppIdentity.verify_proof(proof, app)

There is a Plug available for authenticating applications, AppIdentity.Plug.

plug AppIdentity.Plug,
  headers: ["app-identity-proof"],
  finder: fn %{id: id} = _proof -> IdentityApplications.get(id) end

There is a Tesla Middleware for providing proof generation for clients.

def client(app) do
  middleware = [
    {AppIdentity.TeslaMiddleware, identity_app: app, header: "app-identity-proof"}
  ]
end

Installation

The package can be installed by adding app_identity to your list of dependencies in mix.exs:

def deps do
  [
    {:app_identity, "~> 1.3"}
  ]
end

If you need to use a pre-release version, the dependency structure is slightly different:

def deps do
  [
    {:app_identity, github: "KineticCafe/app_identity", sparse: "elixir"}
  ]
end

If on Elixir 1.13 or later, you can use :subdir instead:

def deps do
  [
    {:app_identity, github: "KineticCafe/app_identity", subdir: "elixir"}
  ]
end

Optional features are present when Plug and/or Tesla are part of your application.

Documentation can found at HexDocs or generated with ex_doc.

Semantic Versioning

AppIdentity uses a Semantic Versioning scheme with one significant change:

  • When PATCH is zero (0), it will be omitted from version references.

Additionally, the major version will generally be reserved for specification revisions.
