AttestationChallenge

@Serializable

data class AttestationChallenge constructor(val issuedAt: Instant, val validity: Duration? = null, val timeZone: TimeZone? = null, val nonce: ByteArray, val attestationEndpoint: String, val proofOID: ObjectIdentifier)(source)

A generic representation of a challenge sent the server.

Constructors

constructor(issuedAt: Instant, validUntil: Instant, timeZone: TimeZone?, nonce: ByteArray, attestationEndpoint: String, proofOID: ObjectIdentifier)

Convenience constructor to pass two instants instead of instant and duration

constructor(issuedAt: Instant, validity: Duration? = null, timeZone: TimeZone? = null, nonce: ByteArray, attestationEndpoint: String, proofOID: ObjectIdentifier)

Properties

attestationEndpoint

val attestationEndpoint: String

The endpoint to post the CSR containing the attestation proof to

issuedAt

@Serializable(with = InstantLongSerializer::class)

val issuedAt: Instant

The issuing time of the nonce. Useful to detect clock drifts and exit early. This is not considered sensible information, as clocks must be in sync anyhow.

nonce

@Serializable(with = ByteArrayBase64UrlSerializer::class)

val nonce: ByteArray

The nonce chosen by the server. Must be at most 128 bytes long, as this is the largest nonce size supported by Android.

proofOID

@Serializable(with = ObjectIdentifierStringSerializer::class)

val proofOID: ObjectIdentifier

The OID to be used for encoding the attestation proof into the signed CSR used to transfer the proof.

timeZone

@Serializable(with = TimeZoneSerializer::class)

val timeZone: TimeZone? = null

The server timezone. Can be omitted if the server does not want to disclose this information

validity

@Serializable(with = DurationWholeSecondsSerializer::class)

val validity: Duration? = null

How long this nonce is considered valid. Can be omitted, if the server does not want to disclose this information.

validUntil

val validUntil: Instant?

Lazily-evaluated property

Functions

equals

open operator override fun equals(other: Any?): Boolean

getRdnSerialNumber

fun getRdnSerialNumber(): AttributeTypeAndValue

Encapsulates the nonce encoded into a KnownOIDs.serialNumber RDN component for easier parsing

hashCode

open override fun hashCode(): Int
