我写了这个扩展方法，但我只有一个参数。

我的 C# 代码：

public static string ToEncrypt(this string key, string passWord)
{
    // Salt and IV is randomly generated each time, but is prepended to encrypted cipher text
    // so that the same Salt and IV values can be used when decrypting.  
    var saltStringBytes = Generate256BitsOfRandomEntropy();
    var ivStringBytes = Generate256BitsOfRandomEntropy();
    var plainTextBytes = Encoding.UTF8.GetBytes(key);

    using (var password = new Rfc2898DeriveBytes(passWord, saltStringBytes, DerivationIterations))
    {
        var keyBytes = password.GetBytes(Keysize / 8);

        using (var symmetricKey = new RijndaelManaged())
        {
            symmetricKey.BlockSize = 256; …
