Overview

Package spiffebundle provides SPIFFE bundle related functionality.

A bundle represents a SPIFFE bundle, a collection authorities for authenticating SVIDs.

You can create a new bundle for a specific trust domain: 

td := spiffeid.RequireTrustDomain("example.org")
bundle := spiffebundle.New(td)

Or you can load it from disk: 

td := spiffeid.RequireTrustDomain("example.org")
bundle := spiffebundle.Load(td, "bundle.json")

The bundle can be initialized with X.509 or JWT authorities: 

td := spiffeid.RequireTrustDomain("example.org")

var x509Authorities []*x509.Certificate = ...
bundle := spiffebundle.FromX509Authorities(td, x509Authorities)
// ... or ...
var jwtAuthorities map[string]crypto.PublicKey = ...
bundle := spiffebundle.FromJWTAuthorities(td, jwtAuthorities)

In addition, you can add authorities to the bundle: 

var x509CA *x509.Certificate = ...
bundle.AddX509Authority(x509CA)
var keyID string = ...
var publicKey crypto.PublicKey = ...
bundle.AddJWTAuthority(keyID, publicKey)

Bundles can be organized into a set, keyed by trust domain: 

set := spiffebundle.NewSet()
set.Add(bundle)

A Source is source of bundles for a trust domain. Both the Bundle and Set types implement Source: 

// Initialize the source from a bundle or set
var source spiffebundle.Source = bundle
// ... or ...
var source spiffebundle.Source = set

// Use the source to query for X.509 bundles by trust domain
bundle, err := source.GetBundleForTrustDomain(td)

Additionally the Bundle and Set types also implement the x509bundle.Source and jwtbundle.Source interfaces: 

// As an x509bundle.Source...
var source x509bundle.Source = bundle // or set
x509Bundle, err := source.GetX509BundleForTrustDomain(td)

// As a jwtbundle.Source...
var source jwtbundle.Source = bundle // or set
jwtBundle, err := source.GetJWTBundleForTrustDomain(td)
