Package-level declarations

What goes in and comes out: requests and presets, results, credential summaries and details, document types, and SdkResult / SdkError.

Types

AcceptanceDecision

enum AcceptanceDecision : Enum<AcceptanceDecision>

AcceptanceResult

data class AcceptanceResult(val decision: AcceptanceDecision, val signatureValid: Boolean, val issuerTrusted: Boolean, val withinValidityWindow: Boolean, val revocation: RevocationState, val revocationDataStale: Boolean, val disclosedClaims: Map<String, String>, val portrait: ByteArray? = null, val reason: String? = null, val revocationCheckedAt: Instant? = null, val issuerName: String? = null, val revocationPublished: Boolean = true)

The single composed verdict a verifier acts on.

AttributeKind

enum AttributeKind : Enum<AttributeKind>

The value type of a CredentialAttribute. Sex is an ISO/IEC 5218 code (0 unknown, 1 male, 2 female, 9 not applicable) rendered as words.

Capabilities

data class Capabilities(val walletPresentQr: Boolean, val walletPresentNfc: Boolean, val verifierScanQr: Boolean, val verifierScanNfc: Boolean, val bleTransfer: Boolean)

What this platform/build supports. iOS asymmetry lives here (wallet cannot present over NFC).

ClaimView

data class ClaimView(val elementId: String, val label: String, val value: String)

One displayable claim: the ISO data-element id, its label, and a rendered value.

CredentialAttribute

data class CredentialAttribute(val id: String, val label: String, val kind: AttributeKind, val description: String = label, val mandatory: Boolean = false, val icon: String? = null, val expiredBadge: String? = null)

A data element of a CredentialType.

CredentialDetail

class CredentialDetail(val id: String, val displayName: String, val docType: String, val portrait: ByteArray?, val claims: List<ClaimView>)

A held credential's claims, for display in the wallet (holder side).

CredentialFormat

enum CredentialFormat : Enum<CredentialFormat>

Credential formats supported in v1.

CredentialNamespace

data class CredentialNamespace(val id: String, val attributes: List<CredentialAttribute>)

One mdoc namespace of a CredentialType and the data elements in it.

CredentialSummary

data class CredentialSummary(val id: String, val format: CredentialFormat, val docType: String, val displayName: String, val validFrom: Long?, val validUntil: Long?)

A held credential, summarized for listing (no sensitive claim values).

CredentialType

data class CredentialType(val docType: String, val displayName: String, val namespaces: List<CredentialNamespace>)

An app-supplied mdoc credential type, so the SDK can label, render and request documents it doesn't ship with (the ISO 18013-5 mDL is built in). Register via com.wallet.config.SdkConfig.credentialTypes.

DocTypes

object DocTypes

Document types the SDK knows out of the box. Apps add their own via CredentialType.

OfferPreview

data class OfferPreview(val issuerName: String, val issuerUrl: String, val credentialName: String, val docType: String?)

What a scanned credential offer is for, shown before the holder accepts it (nothing is redeemed).

PresentationRequest

data class PresentationRequest(val docType: String, val attributes: Set<String> = emptySet(), val namespaces: Map<String, Set<String>> = emptyMap())

What a verifier asks for.

PresentmentState

sealed interface PresentmentState

States emitted by a com.wallet.clients.PresentmentSession.

PresetAnswer

sealed interface PresetAnswer

How a verifier shows a RequestPreset's result.

RequestPreset

data class RequestPreset(val id: String, val section: String, val title: String, val subtitle: String, val request: PresentationRequest, val answer: PresetAnswer = PresetAnswer.Details, val symbol: String = "ID")

A fixed, named request a verifier operator can pick (e.g. "Age over 18").

RequestPresets

object RequestPresets

The built-in verifier presets for the ISO 18013-5 mDL: an age check and a licence check. Apps add their own (for their own CredentialTypes) and pass the list to the verifier screen. Every element is requested with intent-to-retain = false (data minimisation).

RevocationState

enum RevocationState : Enum<RevocationState>

Revocation status of a presented credential. Suspension applies to SD-JWT VC only (mDL is 1-bit).

SdkError

data class SdkError(val kind: SdkError.Kind, val message: String, val cause: Throwable? = null)

Typed error surface.

SdkResult

sealed interface SdkResult<out T>

Result wrapper for suspend calls that can fail without throwing.

Transport

enum Transport : Enum<Transport>

Proximity engagement/transport the user can pick to start a session.

VerificationState

sealed interface VerificationState

States emitted by a com.wallet.clients.VerificationSession.
