我尝试了下面的代码来创建RSA-OAEP和A128 GCM JWE生成器和验证器。它与node.js一起工作，即加密索赔并生成JWE，解密相同的给我索赔。但它并不适用于其他客户端，比如Nimbus Jose，Jose 4j。所以，我肯定错过了什么。
我正在通过阅读https://www.rfc-editor.org/rfc/rfc7516来执行此操作
index.js

var crypto = require('crypto');

var claims = {
    firstName: "vimal"
};

var header = {
    "enc": "A128GCM",
    "alg": "RSA-OAEP"
};

var headerBase64Url = base64url.encode(JSON.stringify(header));
console.log("headerBase64Url : " + headerBase64Url);
console.log("headerBase64Url to UTF8 : " + base64url.decode(headerBase64Url));

var cek = randomstring.generate(16);
console.log("cek : " + cek);

var publicKey = ursa.createPublicKey(fs.readFileSync('./pubkey.pem'));
var encryptedKey = publicKey.encrypt(cek, 'utf8', 'base64');
console.log("encryptedKey : " + encryptedKey);

// var privateKey = ursa.createPrivateKey(fs.readFileSync('./privkey.pkc8.pem'));

// console.log("decryptedKey : " + decryptedKey);

var iv = randomstring.generate(12);
console.log("IV : " + iv);
var cipher = crypto.createCipheriv('aes-128-gcm', cek, iv);
cipher.setAAD(Buffer.from(ascii.toASCII(headerBase64Url)));
var chipherText = cipher.update(JSON.stringify(claims), "utf8", "base64");

ASCII.js

function toASCII(text) {
    var ascii = "";
    for (var f in text) {
        ascii = ascii + text.charCodeAt(f);
    }

    return ascii;
}

module.exports = {
    toASCII: toASCII
};

使用以下命令生成公钥和私钥：

openssl genrsa -out ./privkey.pem 2048

openssl pkcs8 -topk8 -inform pem -in ./privkey.pem -outform pem -nocrypt -out ./privkey.pkc8.pem

openssl rsa -in ./privkey.pkc8.pem -pubout -out ./pubkey.pem

需要做什么来修复代码？
这是我的公钥
