HolderAgent

class HolderAgent(validator: Validator = Validator.newDefaultInstance(), subjectCredentialStore: SubjectCredentialStore = InMemorySubjectCredentialStore(), jwsService: JwsService, coseService: CoseService, val identifier: String, verifiablePresentationFactory: VerifiablePresentationFactory = VerifiablePresentationFactory( jwsService = jwsService, coseService = coseService, identifier = identifier, ), difInputEvaluator: InputEvaluator = InputEvaluator(), val defaultPathAuthorizationValidator: (SubjectCredentialStore.StoreEntry, NormalizedJsonPath) -> Boolean = { _, _ -> true }) : Holder

An agent that only implements Holder, i.e. it can receive credentials form other agents and present credentials to other agents.

getCredentials

open suspend override fun getCredentials(): Collection<Holder.StoredCredential>?

Gets a list of all stored credentials, with a revocation status.

matchInputDescriptorsAgainstCredentialStore

open suspend override fun matchInputDescriptorsAgainstCredentialStore(presentationDefinition: PresentationDefinition, fallbackFormatHolder: FormatHolder?, pathAuthorizationValidator: (SubjectCredentialStore.StoreEntry, NormalizedJsonPath) -> Boolean): KmmResult<Map<InputDescriptor, HolderAgent.CandidateInputMatchContainer?>>

Creates a mapping from the input descriptors of the presentation definition to matching credentials and the fields that would need to be disclosed.

setRevocationList

open override fun setRevocationList(it: String): Boolean

Sets the revocation list ot use for further processing of Verifiable Credentials

storeCredentials

open suspend override fun storeCredentials(credentialList: List<Holder.StoreCredentialInput>): Holder.StoredCredentialsResult
