function importJWK
Re-export
import { importJWK } from "https://deno.land/x/fido2@3.3.2/lib/toolbox.js";

Imports a JWK to a runtime-specific key representation (KeyLike). Either JWK "alg" (Algorithm) Parameter must be present or the optional "alg" argument. When running on a runtime using Web Cryptography API the jwk parameters "use", "key_ops", and "ext" are also used in the resulting CryptoKey. See Algorithm Key Requirements to learn about key to algorithm requirements and mapping.

Examples

Usage

const ecPublicKey = await jose.importJWK(
  {
    crv: 'P-256',
    kty: 'EC',
    x: 'ySK38C1jBdLwDsNWKzzBHqKYEE5Cgv-qjWvorUXk9fw',
    y: '_LeQBw07cf5t57Iavn4j-BqJsAD1dpoz8gokd3sBsOo',
  },
  'ES256',
)

const rsaPublicKey = await jose.importJWK(
  {
    kty: 'RSA',
    e: 'AQAB',

Parameters

jwk: JWK

JSON Web Key.

optional
alg: string

JSON Web Algorithm identifier to be used with the imported key. Default is the "alg" property on the JWK.

optional
octAsKeyObject: boolean

Forces a symmetric key to be imported to a KeyObject or CryptoKey. Default is true unless JWK "ext" (Extractable) is true.

Returns

Promise<KeyLike | Uint8Array>
