Asn1PemDecodable

interface Asn1PemDecodable<A : Asn1Element, out T : Asn1Encodable<A>> : PemDecodable<T> , Asn1Decodable<A, T> (source)

Helper class for decoding simple PEM structures, where the payload is just the DER bytes. By default, does not allow PEM headers, matching the RFC 7468 structures. Override decodeFromTlvWithPemHeaders to customize this.

Properties

pemLabel

abstract val pemLabel: String

Functions

decodeAllFromPem

fun <T> PemDecodable<T>.decodeAllFromPem(src: String): List<T>

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

decodeFromDerWithPemHeaders

fun <A : Asn1Element, T : Asn1Encodable<A>> Asn1PemDecodable<A, T>.decodeFromDerWithPemHeaders(pemHeaders: Iterable<PemHeader>, der: ByteArray): T

decodeFromPem

fun <T> PemDecodable<T>.decodeFromPem(src: String): T

decodeFromPemBlock

open override fun decodeFromPemBlock(src: PemBlock): T

decodeFromTlv

open fun decodeFromTlv(src: A, assertTag: Asn1Element.Tag?): T

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

decodeFromTlvWithPemHeaders

open fun decodeFromTlvWithPemHeaders(pemHeaders: Iterable<PemHeader>, tlv: A): T

doDecode

abstract fun doDecode(src: A): T

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

verifyTag

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

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