C# 中的 AES 加密和 JS 中使用 crypto-js 的解密

Question

用例： 我正在开发一个 C# 服务，我必须将一个加密字符串发送到另一个系统，该系统已经使用 CryptoJS 在 JS 中编码，这将解密我要发送的字符串。 接收系统不会对其实现进行任何更改。他们共享了用于解密的 JS 代码以及我加密所需的凭据。

接收方加密和解密的JS代码

var message = "hello world!!!";

function generateKey(salt, passPhrase, keySize, iterationCount) {
const key = CryptoJS.PBKDF2(passPhrase, CryptoJS.enc.Hex.parse(salt), {
keySize: keySize / 32,
iterations: iterationCount
});
return key;
}

function Encrypt(cipherText) {
const salt = "DUMMYSALT-VALUE-of-Size-32CHARACTERS";
const iv ="DUMMYIV-VALUE-of-Size-32CHARACTERS";
const passPhrase = "SomeSecretPassPhrase";
const keySize = 128
const iterationCount = 1
const key = generateKey(salt, passPhrase, keySize, iterationCount);
const encrypted = CryptoJS.AES.encrypt(cipherText, key, {
iv: CryptoJS.enc.Hex.parse(iv)
});
return encrypted.ciphertext.toString();
}

function Decrypt(cipherText, pass = "SomeSecretPassPhrase") {
const salt = "DUMMYSALT-VALUE-of-Size-32CHARACTERS";
const iv ="DUMMYIV-VALUE-of-Size-32CHARACTERS";
const passPhrase = "SomeSecretPassPhrase";
const keySize = 128
const iterationCount = 1
const key = generateKey(salt, passPhrase, keySize, iterationCount);

const cipherParams = CryptoJS.lib.CipherParams.create({
ciphertext: CryptoJS.enc.Hex.parse(cipherText)
});
const decrypted = CryptoJS.AES.decrypt(cipherParams, key, {
iv: CryptoJS.enc.Hex.parse(iv)
});
return decrypted.toString(CryptoJS.enc.Utf8);
}


var encrypted = Encrypt(message);
//equivalent to CryptoJS.AES.encrypt(CryptoJS.enc.Utf8.parse(message), key);
var decrypted = Decrypt(encrypted);
                                                        

$('#1').text("Encrypted: "+encrypted.toString(CryptoJS.enc.Utf8));
$('#2').text("Decrypted: "+decrypted.toString(CryptoJS.enc.Utf8));

输出 加密：24a935f11a3e0b35dd6604cd7dbee292 解密：你好世界！！！

问题：当我尝试通过 C# 移植它并尝试使用下面的代码加密字符串时，我的加密值不同，而且 JS 代码也无法解密它。

我要加密的代码：

var MyKey = GenerateKey("DUMMYSALT-VALUE-of-Size-32CHARACTERS", "SomeSecretPassPhrase");
var EncryptedString = EncryptString(MyKey, "hello world!!!");


   public byte[] GenerateKey(string saltVal, string passphrase)
        {
            byte[] salt = ConvertHexStringToByteArray("DUMMYSALT-VALUE-of-Size-32CHARACTERS");
            int iterations = 1;
            var rfc2898 = new Rfc2898DeriveBytes(passphrase, salt, iterations);
            byte[] key = rfc2898.GetBytes(16);
            
            return key;
        }

        public string EncryptString(byte[] key, string stringToEncrypt )
        {
            AesManaged aesCipher = new AesManaged();
            aesCipher.KeySize = 128;
            aesCipher.BlockSize = 128;
            aesCipher.Mode = CipherMode.CBC;
            aesCipher.Padding = PaddingMode.PKCS7;
            aesCipher.Key = key;
            aesCipher.IV = ConvertHexStringToByteArray("DUMMYPRESETIV-VALUE-of-Size-32CHARACTERS");
            byte[] b = System.Text.Encoding.UTF8.GetBytes(stringToEncrypt);
            ICryptoTransform encryptTransform = aesCipher.CreateEncryptor();
            byte[] ctext = encryptTransform.TransformFinalBlock(b, 0, b.Length);
            System.Console.WriteLine("IV:" + Convert.ToBase64String(aesCipher.IV));           
            System.Console.WriteLine("Cipher text: " + Convert.ToBase64String(ctext));
            return Convert.ToBase64String(ctext);
        }

        public byte[] ConvertHexStringToByteArray(string hexString)
        {
            int NumberChars = hexString.Length;
            byte[] bytes = new byte[NumberChars / 2];
            for (int i = 0; i < NumberChars; i += 2)
                bytes[i / 2] = Convert.ToByte(hexString.Substring(i, 2), 16);
            return bytes;
        }

我不确定我是否执行了与 JS 方法 CryptoJS.enc.Hex.parse() 等效的正确操作 ,
