Asn1Integer

@Serializable(with = Asn1IntegerSerializer::class)

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

equals

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

hashCode

open override fun hashCode(): Int

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

toString

open override fun toString(): String

twosComplement

abstract fun twosComplement(): ByteArray
