Deno throws when using jose.importJWK and ES256?

[jdjkelly]

I'm using Deno v1.16.3 and jose 4.3.7.

This simple example:

import * as jose from "https://deno.land/x/[email protected]/index.ts"

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

console.log(ecPublicKey)

Throws this exception from Deno's implementation of crypto.subtle.importKey:

error: Uncaught NotSupportedError: Unrecognized algorithm name
  return crypto.subtle.importKey('jwk', keyData, ...rest)
                       ^

I don't think I'm doing anything wrong - this is basically the same thing as what's in jose's importJWK example itself.

As per #266 - ⚠️ Note that Deno's implementation of Web Cryptography API is still underway.

importKey is not implemented in Deno yet.

You're not doing anything wrong. Deno's Web Cryptography API just needs to mature.
