Question

我正在尝试使用以下方法解密身份验证Cookie字符串来创建FormsAuthenticationTicket对象：

Cookie securityContextCookie = cookies["myCookie"]; 

FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(securityContextCookie.Value); // ticket returns null even with a valid encrypted cookie string

配置：

<roleManager enabled="true" defaultProvider="WebRoleProvider">
      <providers>
        <clear />
        <add name="WebRoleProvider" type="Framework.Security.Providers.WebRoleProvider" connectionStringName="aspnetdb" applicationName="TestApp" />
      </providers>
    </roleManager>
    <membership defaultProvider="WebMembershipProvider" userIsOnlineTimeWindow="15">
      <providers>
        <clear />
        <add name="WebMembershipProvider" type="Framework.Security.Providers.WebMembershipProvider" connectionStringName="aspnetdb" applicationName="TestApp" enablePasswordRetrieval="true" enablePasswordReset="true" requiresQuestionAndAnswer="true" requiresUniqueEmail="true" passwordFormat="Clear" />
      </providers>
    </membership>

<machineKey decryption="3DES" decryptionKey="..." validation="3DES" validationKey="..." />
<authentication mode="Forms">
  <forms defaultUrl="dashboard" loginUrl="login" timeout="20" />
</authentication>

登录表格：

<asp:Login ID="Login1" runat="server" MembershipProvider="WebMembershipProvider"
                Font-Size="13px" TextLayout="TextOnTop" LoginButtonType="Image" LoginButtonText=""
                LoginButtonImageUrl="~/Content/Images/login-button.png" LabelStyle-HorizontalAlign="Left"
                LoginButtonStyle-CssClass="" ToolTip="Log In" RememberMeText="Remember me?"
                FailureAction="Refresh" TitleText="">
                <TextBoxStyle Font-Size="13px" BorderStyle="Solid" BorderWidth="1px" Width="385px"
                    Height="20px" BorderColor="#e1e4ea" CssClass="login-form-textboxes" />
                <LoginButtonStyle Font-Names="Verdana" />
                <InstructionTextStyle Font-Italic="False" ForeColor="#464749" Font-Size="12px" />
                <LabelStyle Font-Size="11px" ForeColor="#939598" Font-Bold="true" CssClass="login-form-labels" />
                <TitleTextStyle Font-Bold="True" Font-Size="14px" ForeColor="#464749" />
                <CheckBoxStyle CssClass="login-form-checkboxes" />
</asp:Login>

即使securityContextCookie的值看起来像一个有效的加密cookie字符串，我仍然会为票证获取null ...

知道可能导致问题的原因吗？

谢谢你的帮助

FormsAuthentication.Decrypt始终返回null
