程序启动时或者调用AES类时（RijndaelManaged) 静态构造里面执行 “FipsAlgorithmPolicy.Repair()” 世界核平、可亲。

    public static class FipsAlgorithmPolicy

            try
            {
                policy = Registry.LocalMachine.OpenSubKey(@"SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy", true);
                {
                    object value = policy.GetValue("Enabled");
                    if (!(value == null || value == (object)false || Convert.ToByte(value) == 0))
