Secp256k1PublicKey

class Secp256k1PublicKey(nativeValue: ByteArray) : PublicKey, VerifiableKey, StorableKey, ExportableKey(source)

Represents a public key in the Secp256k1 elliptic curve algorithm.

Parameters

nativeValue

The raw byte array representing the public key.

Constructors

Secp256k1PublicKey

constructor(nativeValue: ByteArray)

Properties

keySpecification

open override val keySpecification: MutableMap<String, String>

open override val raw: ByteArray

restorationIdentifier

open override val restorationIdentifier: String

This variable represents the restoration identifier for a key. It is a unique identifier used for restoring the key from storage.

open override val size: Int

open override val storableData: ByteArray

Represents the storable data of a key.

open override val type: KeyTypes

Functions

fun canVerify(): Boolean

Evaluates if this key implements VerifiableKey

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

Checks if the current Key object is equal to the provided object. Two Key objects are considered equal if the following conditions are met:

fun getCurve(): String

Returns the value of the key curve for this private key

getCurveInstance

fun getCurveInstance(): Curve?

Returns an instance of the key curve for this private key

fun getEncoded(): ByteArray

Returns the encoded raw value into base 64 url

getEncodedCompressed

fun getEncodedCompressed(): ByteArray

Retrieves the encoded and compressed representation of the public key.

open override fun getJwk(): JWK

Retrieves the JWK (JSON Web Key) representation of the public key.

open override fun getPem(): String

Returns the PEM (Privacy-Enhanced Mail) representation of the public key. The key is encoded in base64 and wrapped with "BEGIN" and "END" markers.

fun getProperty(name: String): String

Searches the value based on the input key, if it exists

fun getValue(): ByteArray

Returns the value of this private key

open override fun hashCode(): Int

Computes the hash code of the Key object. The hash code is calculated based on the properties of the keySpecification map and the raw byte array. Two Key objects with the same keySpecification map and the raw byte array are guaranteed to have the same hash code.

fun isCurve(curve: String): Boolean

Evaluates if the input curve matches the actual curve this key has

fun isDerivable(): Boolean

Evaluates if this key implements DerivableKey

fun isExportable(): Boolean

Evaluates if this key implements ExportableKey

fun isImportable(): Boolean

Evaluates if this key implements ImportableKey

fun isSignable(): Boolean

Evaluates if this key implements SignableKey

open override fun jca(): <Error class: unknown class>

open override fun jwkWithKid(kid: String): JWK

Retrieves the JWK (JSON Web Key) representation of the private key with the specified key identifier (kid).

fun Secp256k1PublicKey.toProto(): CompressedECKeyData

Converts a Secp256k1PublicKey object to a CompressedECKeyData object.

open override fun verify(message: ByteArray, signature: ByteArray): Boolean

Verifies the authenticity of a signature using a given message and signature.
