How to create pem format from json for the production? I have keys in json format.

我的方法是在app.js文件里写一个gen-jwks的GET方法路由，然后在terminal中得到类似以下字符串

-----BEGIN EC PRIVATE KEY-----                                  
MHcCAQEEIFttQW8HLog4gPR90X6zUxvpqzIc+ATJNZbsfxFCJZ68oAoGCCqGSM49

-----END EC PRIVATE KEY-----                                    

-----BEGIN EC PRIVATE KEY-----

{"keys":[{"kty":"EC","kid":"inCo96FXYYPKC0e3eOWqunNAbkPhuQ6Oc1dJjlIUWXk","crv":"P-256","x":"AFXSiTqDjEHwwdgQRksLo3s-Mzwo_dr6OwAwtfCjFWY","y":"3NgmhtCo8Baezd8Jj-G_pMrguXPyOEtubpjQ_dRS0So","use":"sig","alg":"ES256"},{"kty":"EC","kid":"6qYAQ96uSN2eyx5P086PyFVxTV3lN

以上字符串第一个区块为签名秘钥，第二个区块为加密秘钥。你需要将这两个区块分别存储为相应的pem文件。第三个区块为JWKS。你需要将第三个区块的内容放在公开可访问的URL地址里（Singpass后台的JWKS Endpoint）。

生成以上字符串的代码如下：

只需在terminal里运行npm start，然后浏览器访问http://localhost:3001/gen-jwks就可得到

app.get("/gen-jwks", function (req, res) {
  async function generateKey(){
    let key = crypto.generateKeyPairSync('ec', {
      namedCurve: 'prime256v1',
      publicKeyEncoding: {
        type: 'spki',
        format: 'pem',
      },
      privateKeyEncoding: {
        type: 'pkcs8',
        format: 'pem',
      },
    });
    let cryptoKey = await jose.JWK.asKey(key.privateKey, 'pem');
    console.log(cryptoKey.toPEM(true)); //!important
    return cryptoKey;
  }

  async function generateJwks() {
    //Creating Signing Key
    let signingKey = await generateKey();
    let publicSigningKeyJSON = signingKey.toJSON();

    //Creating Encryption Key
    let encryptionKey = await generateKey();
    let publicEncryptionKeyJSON = encryptionKey.toJSON();

    let jwks = {
      keys: [{...publicSigningKeyJSON,
        ...{use: 'sig'},
        ...{crv: 'P-256'},
        ...{alg: 'ES256'},
      },
        {...publicEncryptionKeyJSON,
          ...{use: 'enc'},
          ...{crv: 'P-256'},
          ...{alg: 'ECDH-ES+A256KW'},
        }]};

    console.log(JSON.stringify(jwks));
  }

  generateJwks();
});

注意

config/config.js 文件里的AUTHORIZE_JWKS_URL、MYINFO_JWKS_URL请保持demo里的值不变
