C# AES 加密解密

AES加密

        public static string AESEncrypt(string toEncrypt, string key, string iv = "xxxxxxx")
        {
            byte[] keyArray = Encoding.UTF8.GetBytes(key);

            byte[] toEncryptArray = Encoding.UTF8.GetBytes(toEncrypt);

            RijndaelManaged rDel = new RijndaelManaged();
            rDel.Key = keyArray;
            rDel.IV = ivArray;
            rDel.Mode = CipherMode.CBC;
            rDel.Padding = PaddingMode.Zeros;
            ICryptoTransform cTransform = rDel.CreateEncryptor();
            byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
            return Convert.ToBase64String(resultArray, 0, resultArray.Length);
