privateKey.x missing for Elliptic Curve JWT keys

[d70-t]

Version: Deno 2.1.7

According to RFC 8037 2, OKP private key JWTs must include all members required for the public key counterpart. In particular, private and public keys must include kty, crv and x, while the private key must additionally contain d.

However, when runninng the following code:

import { generateKeyPairSync } from "node:crypto"

console.log(generateKeyPairSync('ed25519', {
    publicKeyEncoding: { type: 'spki', format: 'jwk' },
    privateKeyEncoding: { type: 'pkcs8', format: 'jwk' }
}))

• in deno: privateKey.x is missing
• in node: privateKey.x is available
