IndefiniteLength

class IndefiniteLength : CryptoSignature.EC, CryptoSignature.NotRawByteEncodable(source)

Types

object Companion

Properties

humanReadableString

open val humanReadableString: String

jcaSignatureBytes

val CryptoSignature.jcaSignatureBytes: ByteArray

In Java EC signatures are returned as DER-encoded, RSA signatures however are raw bytearrays

val r: BigInteger

r - ECDSA signature component

val s: BigInteger

s - ECDSA signature component

open override val signature: Asn1Element

Functions

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

open override fun encodeToTlv(): Asn1Element

Encodes the implementing object into an A

encodeToTlvBitString

open override fun encodeToTlvBitString(): Asn1Element

encodeToTlvOrNull

open fun encodeToTlvOrNull(): Asn1Element?

Exception-free version of encodeToTlv

encodeToTlvSafe

open fun encodeToTlvSafe(): KmmResult<Asn1Element>

Safe version of encodeToTlv, wrapping the result into a KmmResult

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

Two signatures are considered equal if r and s are equal. This is true even if they are of definite length, and the lengths differ.

fun guessCurve(): CryptoSignature.EC.DefiniteLength

tries to guess the curve from the bit length of the indefinite-length r/s values this will work well in the vast majority of cases, but may fail in pathological edge cases (when r/s have a very large number of leading zeroes)

open override fun hashCode(): Int

open override fun toString(): String

fun withCurve(c: ECCurve): CryptoSignature.EC.DefiniteLength

specifies the curve context for this signature, allowing it to be converted to raw bytes

withScalarByteLength

fun withScalarByteLength(l: UInt): CryptoSignature.EC.DefiniteLength

specifies the curve's scalar byte length for this signature, allowing it to be converted to raw bytes
