c# - "Error occurred during a cryptographic operation"解密 Forms cookie 时

Question

我已经将我的网站上传到虚拟主机，但出现了这个错误；
'加密操作期间发生错误。'。

我做了一些研究，似乎经过验证的 cookie 绑定(bind)到 MachineKey(使用 webhost 时有所不同)。

我找到了应该可以解决此问题的方法，但错误仍然存​​在。

代码:

/// <summary>
    /// This method removes a cookie if the machine key is different than the one that saved the cookie;
    /// </summary>
    protected void Application_Error(object sender, EventArgs e)
    {
        var error = Server.GetLastError();
        var cryptoEx = error as CryptographicException;
        if (cryptoEx != null)
        {
            FederatedAuthentication.WSFederationAuthenticationModule.SignOut();
            Global.Cookies.FormAuthenticated Cookie = new Global.Cookies.FormAuthenticated();
            Cookie.Delete();
            Server.ClearError();
        }
    }

对于那些没有解决问题的人，我在我的 web.config 中缺少用于加密/解密的“machineKey”条目
