Asn1Integer

@Serializable(with = Asn1IntegerSerializer::class)

sealed class Asn1Integer : Asn1Encodable<Asn1Primitive> (source)

A very simple implementation of an ASN.1 variable-length integer. It is only good for reading from and writing to ASN.1 structures. It is not a BigInt, nor does it define any operations. It has a sign though, and supports twosComplement representation and converting fromTwosComplement. Hence, it directly interoperates with Kotlin MP BigNum and the JVM BigInteger.

Functions

encodeToAsn1ContentBytes

fun Asn1Integer.encodeToAsn1ContentBytes(): ByteArray

Encodes this number into a ByteArray using the same encoding as the Asn1Primitive.content property of an Asn1Primitive containing an ASN.1 INTEGER

encodeToAsn1Primitive

fun Asn1Integer.encodeToAsn1Primitive(): Asn1Primitive

Produces an INTEGER as Asn1Primitive

encodeToDer

open fun encodeToDer(): ByteArray

Convenience function to directly get the DER-encoded representation of the implementing object

encodeToDerOrNull

open fun encodeToDerOrNull(): ByteArray?

Exception-free version of encodeToDer

encodeToDerSafe

open fun encodeToDerSafe(): KmmResult<ByteArray>

Safe version of encodeToDer, wrapping the result into a KmmResult

encodeToTlv

open override fun encodeToTlv(): Asn1Primitive

Encodes the implementing object into an A

encodeToTlvOrNull

open fun encodeToTlvOrNull(): Asn1Primitive?

Exception-free version of encodeToTlv

encodeToTlvSafe

open fun encodeToTlvSafe(): KmmResult<Asn1Primitive>

Safe version of encodeToTlv, wrapping the result into a KmmResult

equals

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

hashCode

open override fun hashCode(): Int

isZero

fun isZero(): Boolean

toAsn1VarInt

fun Asn1Integer.toAsn1VarInt(): ByteArray

Encodes this number using varint encoding as used within ASN.1: groups of seven bits are encoded into a byte, while the highest bit indicates if more bytes are to come

toJavaBigInteger

fun Asn1Integer.toJavaBigInteger(): <Error class: unknown class>

toString

open override fun toString(): String

twosComplement

abstract fun twosComplement(): ByteArray

Encodes the Asn1Integer to its minimum-size twos-complement encoding. Non-empty.

withImplicitTag

open infix fun withImplicitTag(tag: Asn1Element.Tag): Asn1Element

Creates a new implicitly tagged ASN.1 Element from this ASN.1 Element. NOTE: The TagClass of the provided tag will be used! If you want the result to have TagClass.CONTEXT_SPECIFIC, also invoke tag withClass TagClass.CONTEXT_SPECIFIC!. If a CONSTRUCTED Tag is applied to an ASN.1 Primitive, the CONSTRUCTED bit is overridden and set to zero

open infix fun withImplicitTag(template: Asn1Element.Tag.Template): Asn1Element

Creates a new implicitly tagged ASN.1 Element from this ASN.1 Structure. If the provided template's tagClass is not set, the class of the resulting structure defaults to TagClass.CONTEXT_SPECIFIC. If a CONSTRUCTED Tag is applied to an ASN.1 Primitive, the CONSTRUCTED bit is overridden and set to zero

open infix fun withImplicitTag(tagValue: ULong): Asn1Element

Creates a new implicitly tagged ASN.1 Element from this ASN.1 Element. Sets the class of the resulting structure to TagClass.CONTEXT_SPECIFIC
