JavaScript: 已在C#中加密的描述字符串

Question

我创建了这个方法来使用密钥加密字符串：

 public static string EncryptString(string key, string plainText)
        {
            byte[] iv = new byte[16];
            byte[] array;

            using (Aes aes = Aes.Create())
            {
                aes.Key = Encoding.UTF8.GetBytes(key);
                aes.IV = iv;

                ICryptoTransform encryptor = aes.CreateEncryptor(aes.Key, aes.IV);

                using (MemoryStream memoryStream = new MemoryStream())
                {
                    using (CryptoStream cryptoStream = new CryptoStream((Stream)memoryStream, encryptor, CryptoStreamMode.Write))
                    {
                        using (StreamWriter streamWriter = new StreamWriter((Stream)cryptoStream))
                        {
                            streamWriter.Write(plainText);
                        }

                        array = memoryStream.ToArray();
                    }
                }
            }

            return Convert.ToBase64String(array);
        }

但是我在JS中也需要这个方法，来解密同样的字符串。

我想知道

AES、编码。UTF8.GetBytes、ICryptoTransform、Cryptostreammode 和 MemoryStream。

JS中存在这些吗？

这个方法在 JS 中还能用吗？

使用您的 C# 代码通过 public static string EncryptString(string key, string plainText) 加密字符串，我得到以下结果：

EncryptString("xxxxxxxxxxxxxxxx", "Hello World") -> "yM377gXxX5Du71hgkPH+Fg=="

要扭转这一局面，您可以查看此 Javascript 代码：

const key = "xxxxxxxxxxxxxxxx";
const msg = "yM377gXxX5Du71hgkPH+Fg==";

const decrypted = CryptoJS.AES.decrypt(
  msg, 
  CryptoJS.enc.Utf8.parse(key),
  { mode: CryptoJS.mode.ECB }
);

console.log(decrypted.toString(CryptoJS.enc.Utf8));
