IndefiniteLength

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

Types

object Companion

Properties

humanReadableString

open val humanReadableString: String

val CryptoSignature.iosEncoded: ByteArray

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

val CryptoSignature.x509Encoded: Asn1Primitive

Signature encoded as per X.509:

Functions

open fun encodeToDer(): ByteArray

encodeToDerOrNull

open fun encodeToDerOrNull(): ByteArray?

encodeToDerSafe

open fun encodeToDerSafe(): KmmResult<ByteArray>

open override fun encodeToTlv(): Asn1Sequence

encodeToTlvOrNull

open fun encodeToTlvOrNull(): Asn1Element?

encodeToTlvSafe

open fun encodeToTlvSafe(): KmmResult<Asn1Element>

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

withImplicitTag

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

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

open infix fun withImplicitTag(tagValue: ULong): Asn1Element

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
