Companion

object Companion : Asn1Serializer<Asn1Primitive, Asn1Integer> (source)

Properties

descriptor

open override val descriptor: SerialDescriptor

leadingTags

open override val leadingTags: Set<Asn1Element.Tag>

Leading ASN.1 tags this serializer can decode/encode.

ONE

val ONE: Asn1Integer.Positive

ZERO

val ZERO: Asn1Integer.Positive

Functions

decodeFromAsn1ContentBytes

fun Asn1Integer.Companion.decodeFromAsn1ContentBytes(bytes: ByteArray): Asn1Integer

Decodes a Asn1Integer from bytes assuming the same encoding as the Asn1Primitive.content property of an Asn1Primitive containing an ASN.1 INTEGER

decodeFromDer

fun <A : Asn1Element, T : Asn1Encodable<A>> Asn1Decodable<A, T>.decodeFromDer(src: ByteArray, assertTag: Asn1Element.Tag? = null): T

Convenience method, directly DER-decoding a byte array to T

fun <A : Asn1Element, T : Asn1Encodable<A>> Asn1Decodable<A, T>.decodeFromDer(src: Source<*>, assertTag: Asn1Element.Tag? = null): T

decodeFromDerOrNull

fun <A : Asn1Element, T : Asn1Encodable<A>> Asn1Decodable<A, T>.decodeFromDerOrNull(src: ByteArray, assertTag: Asn1Element.Tag? = null): T?

Exception-free version of decodeFromDer

decodeFromTlv

open override fun decodeFromTlv(src: Asn1Primitive, assertTag: Asn1Element.Tag?): Asn1Integer

Processes an A, parsing it into an instance of T

decodeFromTlvOrNull

fun <A : Asn1Element, T : Asn1Encodable<A>> Asn1Decodable<A, T>.decodeFromTlvOrNull(src: A, assertTag: Asn1Element.Tag? = null): T?

Exception-free version of Asn1Decodable.decodeFromTlv

deserialize

open override fun deserialize(decoder: Decoder): Asn1Integer

Decodes one ASN.1-backed value via DER bytes.

doDecode

open override fun doDecode(src: Asn1Primitive): Asn1Integer

Actual element-specific decoding function. By default, this is invoked after verifyTag

fromByteArray

fun fromByteArray(magnitude: ByteArray, sign: Asn1Integer.Sign): Asn1Integer

Constructs an Asn1Integer from its sign-magnitude representation

fromDecimalString

fun fromDecimalString(input: String): Asn1Integer

Constructs an Asn1Integer from a decimal string

fromTwosComplement

fun fromTwosComplement(input: ByteArray): Asn1Integer

Constructs an Asn1Integer from its twos-complement byte representation

fromUnsignedByteArray

fun fromUnsignedByteArray(magnitude: ByteArray): Asn1Integer.Positive

Constructs a non-negative Asn1Integer from its unsigned magnitude representation

serialize

open override fun serialize(encoder: Encoder, value: Asn1Integer)

Encodes one ASN.1-backed value via DER bytes.

verifyTag

open override fun verifyTag(src: Asn1Primitive, assertTag: Asn1Element.Tag?)

Specify assertTag for verifying implicitly tagged elements' tags (and better not override this function).
