publicKey

TypeScript

get publicKey(): Curve25519_Signing_PublicKey

Swift declaration

var publicKey: Curve25519.Signing.PublicKey { get }

get · iOS 13.0+

rawRepresentation

TypeScript

get rawRepresentation(): ArrayBuffer

Swift declaration

var rawRepresentation: Data { get }

The raw representation of the key as a collection of contiguous bytes.

init · iOS 13.0+

init

TypeScript

static initRawRepresentation(data: ArrayBuffer): Curve25519_Signing_PrivateKey

Swift declaration

init<D>(rawRepresentation data: D) throws where D : ContiguousBytes

Creates a Curve25519 private key for signing from a data representation. - Parameters: - data: A representation of the key as contiguous bytes from which to create the key.

method · iOS 13.0+

signature

TypeScript

signature(data: ArrayBuffer): ArrayBuffer

Swift declaration

func signature<D>(for data: D) throws -> Data where D : DataProtocol

Generates an EdDSA signature over Curve25519. - Parameters: - data: The data to sign. - Returns: The signature for the data. Although not required by [RFC 8032](https://tools.ietf.org/html/rfc8032), which describes the Edwards-Curve Digital Signature Algorithm (EdDSA), the CryptoKit implementation of the algorithm employs randomization to generate a different signature on every call, even for the same data and key, to guard against side-channel attacks.

init

TypeScript

static init(): Curve25519_Signing_PrivateKey

Swift declaration

init()

Creates a random Curve25519 private key for signing.
