解密一个c# AES加密

我想解密JavaScript中的文本。

我加密c#中的文本。这是我的c#加密代码:

    readonly byte[] _salt = new byte[] { 48,94,2,4,9,4,52,222,12,65 };
    private string getEncryptedString(string text, string password)
    {
        string retCryptedString = null;
        byte[] retCryptedByteArr = null;
        retCryptedByteArr = encryptStringToBytes(text, createHash(password));
        retCryptedString = Convert.ToBase64String(retCryptedByteArr);
        return retCryptedString;
    }
    private Rfc2898DeriveBytes createHash(string password)
    {
        Rfc2898DeriveBytes hash = default(Rfc2898DeriveBytes);
        hash = new Rfc2898DeriveBytes(password, _salt);
        return hash;
    }
    private byte[] encryptStringToBytes(string Text, Rfc2898DeriveBytes hash)
    {
        RijndaelManaged encryption = new RijndaelManaged();
        RijndaelManaged rijAlg = new RijndaelManaged();
        byte[] encrypted = null;
        ICryptoTransform encryptor;
        if (Text == null || Text.Length <= 0)
        {
            throw new ArgumentNullException("No text");
        }
        rijAlg = (RijndaelManaged)Rijndael.Create();
        rijAlg.Key = hash.GetBytes(encryption.KeySize / 8);
        rijAlg.IV = hash.GetBytes(encryption.BlockSize / 8);
        encryptor = rijAlg.CreateEncryptor(rijAlg.Key, rijAlg.IV);
        using (MemoryStream ms_Encrypt = new MemoryStream())
        {
            using (CryptoStream cs_Encrypt = new CryptoStream(ms_Encrypt, encryptor, CryptoStreamMode.Write))
            { 
                using (StreamWriter sw_Encrypt = new StreamWriter(cs_Encrypt))
                {
                    sw_Encrypt.Write(Text);
                }
                encrypted = ms_Encrypt.ToArray();
            }
        }
        return encrypted;
    }

我尝试了很多库(例如crypto-js)。但是我无法解密它，因为我不知道如何生成密钥和iv。

当我生成PBKDF2密钥时，我不能将其添加到解密中。

解密一个c# AES加密

//Generic Handler
public void ProcessRequest(HttpContext context)
{
string EncryptedString = context.Request.QueryString["encrypted"];
response.write(decryptedString(EncryptedString);
}

//javascript
$.get("MyHandler.ashx?encrypted=YourEncryptedString").done(function(response){
var DecryptedString = response
});
