如何在node-jose中指定用于加密的JWKS证书

Question

我正在尝试将node-jose配置为使用来自目的地的jwks证书，但正在努力让node-jose使用该证书。 jwks证书如下所示：

{
    "kid": "aaaa",
    "kty": "RSA",
    "alg": "RS384",
    "exp": REDACTEDNUMBER10YEARSAWAY,
    "n": "q_REDACTED",
    "e": "AXXX",
    "use" : "enc",
    "x5c": ["MIIDAzREDACTED"]
},

这是我尝试设置node-jose并加密jwt（在异步函数中）的方式：

ks = await jose.JWK.asKeyStore([{
  kid: "aaaa",
  kty: "RSA",
  alg: "RS384",
  use: "enc",
  n: "q_REDACTED",
  e: "AXXX",
  x5c: ["MIIDAzREDACTED"]
}]);

ejwt = await jose.JWE.createEncrypt(
  {format: 'compact'},
  {
    key: ks.get("aaaa"),
    header: {alg: "RS384", use: "enc" }
  }
);
// createEncrypt doesn't resolve key.

将其用于密钥库可以工作：

ks = await jose.JWK.asKeyStore([{
    kid: 'mykey',
    kty: 'oct',
    k: 'randomkey',
    use: 'enc'
}]);
// works with createEncrypt using header: { alg: 'dir', use: 'enc' }
