0.5.0

cryptography-serialization-asn1-modules/dev.whyoleg.cryptography.serialization.asn1.modules

Package-level declarations

ASN.1 modules/declarations from different RFCs, f.e. SubjectPublicKeyInfo from RFC5280 and PrivateKeyInfo from RFC5208

Types

AlgorithmIdentifier

interface AlgorithmIdentifier

AlgorithmIdentifierSerializer

@ExperimentalSerializationApi

abstract class AlgorithmIdentifierSerializer<AI : AlgorithmIdentifier> : KSerializer<AI>

EcdsaSignatureValue

@Serializable

class EcdsaSignatureValue(val r: BigInt, val s: BigInt)

EcKeyAlgorithmIdentifier

class EcKeyAlgorithmIdentifier(val parameters: EcParameters?) : KeyAlgorithmIdentifier

@Serializable

value class EcParameters(val namedCurve: ObjectIdentifier)

Overall while it's CHOICE in ASN.1, but only namedCurve is allowed

@Serializable

value class EcPoint(val bytes: ByteArray)

This is EC publicKey representation for SubjectPublicKeyInfo

@Serializable

class EcPrivateKey(val version: Int, val privateKey: ByteArray, val parameters: EcParameters? = null, val publicKey: BitArray? = null)

KeyAlgorithmIdentifier

@Serializable(with = KeyAlgorithmIdentifierSerializer::class)

interface KeyAlgorithmIdentifier : AlgorithmIdentifier

@Serializable

class PrivateKeyInfo(val version: Int, val privateKeyAlgorithm: KeyAlgorithmIdentifier, val privateKey: ByteArray)

Attributes is not yet supported:

RsaKeyAlgorithmIdentifier

object RsaKeyAlgorithmIdentifier : KeyAlgorithmIdentifier

@Serializable

class RsaPrivateKey(val version: Int, val modulus: BigInt, val publicExponent: BigInt, val privateExponent: BigInt, val prime1: BigInt, val prime2: BigInt, val exponent1: BigInt, val exponent2: BigInt, val coefficient: BigInt)

OtherPrimeInfos is not supported yet:

@Serializable

class RsaPublicKey(val modulus: BigInt, val publicExponent: BigInt)

SubjectPublicKeyInfo

@Serializable

class SubjectPublicKeyInfo(val algorithm: KeyAlgorithmIdentifier, val subjectPublicKey: BitArray)

UnknownKeyAlgorithmIdentifier

class UnknownKeyAlgorithmIdentifier(val algorithm: ObjectIdentifier) : KeyAlgorithmIdentifier
