public class ProviderMetadataCredentialResolver
extends BasicJOSEObjectCredentialResolver
implements InitializableComponent

A LocalJOSEObjectCredentialResolver that resolves credentials from the jwks_uri of an OpenID Provider. Further filtering of credentials is provided by the AbstractCriteriaFilteringCredentialResolver parent class.

Note, only RSA or EC keys are resolved as these are the only key types which should be exposed in public JWKS documents.

                                          throws ResolverException

resolveFromMetadata

@Nonnull
protected Collection<Credential> resolveFromMetadata(@Nonnull
 CriteriaSet criteriaSet,
 @Nonnull
 OIDCProviderMetadata metadata)

Fetch the remote JWK Set from the jwk_uri in the OpenID Provider's metadata. Convert each JWK into a Credential and return. Only supports EC (key agreement) and RSA (key encryption) keys.

If a keyId is passed through in the criteria set, it is used as a parameter to the remote JWK cache. This ensures if the key is not found any cached keyset document, the document is re-fetched irrespective of the cache entry expiry.

Parameters:

criteriaSet - the criteria set

metadata - the OpenID Provider's metadata

Returns:

a collection of credentials that represents EC and RSA keys in the remote JWK Set (if any)
