Externalising Configuration

Warden Supreme configuration consists of two parts:

Attestation policy configuration as explained in Attestation Policy Configuration, split into
AndroidAttestationConfiguration for Android specifics
IosAttestationConfiguration for iOS specifics
Configuration related to fully integrated attestation, such as OIDs used inside attestation proofs (CSRs) and key constraints, as explained in Attestation Verifier Setup.

To externalise such configuration conveniently, use the umbrella SupremeConfiguration. It includes both the platform-specific configurations and the properties related to fully integrated attestation.
SupremeConfiguration has canonical serialised representations (JSON and YAML) and comes with the following (de)serialisation functions:

toJsonString() and fromJsonString()
toYamlString() and fromYamlString()
toJsonObject() and fromJsonObject()

This is required for externalising configurations, as using Spring Boot's internal config loader to construct configurations is discouraged due to issues with handling nullable properties.

YAML with Defaults for a Sample Android and iOS App

The below example shows every configuration property in YAML form. It uses a single Android app and a single iOS app. Android revocation checks use the default Google revocation list, as well as a custom file-based revocation list. All other properties show their default values.
You can download the below example here.

It is possible to add time sources other than the system clock and externalise their configurations as well by implementing SupremeConfiguration.Clock and registering the classes for serialisation using SupremeConfiguration.Clock.registry.

Both AndroidAttestationConfiguration and IosAttestationConfiguration are useful on their own if you don't opt for fully integrated attestation, which is why they also have canonical serialised representations (JSON and YAML) and expose the same (de)serialisation functions as SupremeConfiguration. All three and their companion objects implement the same interface tandem to keep the API consistent.

YAML for a Sample App

The below example shows every configuration property in YAML form. Applications aside, all properties show their default values, which means that a minimum configuration needs to contain only app information. As for deviations with respect to revocation:

An HTTP proxy is configured for the default HTTP-based revocation checker using the official Google revocation list.
A file-based revocation list is configured to allow for manually revoking certificates.

The HTTP loader used to fetch Google-official revocation lists can also be used generically for any HTTP-based revocation checks. The only difference is in the configuration, as shown in the example below.

Custom HTTP Revocation List Loader Configuration

- type: http
  value: 
    url: 'https://superstrict.revocation.example.org/json'
    fallbackRevocationListValiditySeconds: 60
    preferHeaderBasedExpiry: false
    proxyConfig: 
      type: HTTP
      url: 'https://localhost:2345'

It is possible to create entirely new loaders and even externalise their configuration by implementing an AndroidRevocationList.Loader for the actual loader itself and an AndroidRevocationList.Loader.Configuration for the externalisable configuration. The latter must be marked as @Serializable and registered using the AndroidRevocationList.loaderRegistry before the first configuration reading or writing happens.
