我有一个 SharePoint 2010 服务应用程序，当我尝试在通道上执行一些代码时收到错误消息：

此上下文不支持加密算法''。System.NotSupportedException：此上下文不支持加密算法''。

实际上只有两个 '' 引号，它们之间没有任何内容。我正在为我的 authenticationMode 使用 IssuedToken。这是我的 web.config 文件：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.web>
        <compilation debug="true" defaultLanguage="C#" />
    </system.web>
    <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="TLAPITypeBehaviors" >
                    <serviceMetadata httpGetEnabled="true" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <services>
            <service name="AF.TipAndLeadAPI.TipAndLeadAPIServiceApplication" behaviorConfiguration="TLAPITypeBehaviors">
                <endpoint binding="customBinding" bindingConfiguration="TLAPIServiceHttpBinding"
                          contract="AF.TipAndLeadAPI.ITipAndLeadAPIContract"
                          address="" />
            </service>
        </services>
        <bindings>
            <customBinding>
                <binding name="TLAPIServiceHttpBinding">
                    <security authenticationMode="IssuedTokenOverTransport" allowInsecureTransport="true" />
                    <textMessageEncoding>
                        <readerQuotas maxStringContentLength="2048576000" maxArrayLength="2097152000" />
                    </textMessageEncoding>
                    <httpTransport maxReceivedMessageSize="2162688" authenticationScheme="Anonymous" useDefaultWebProxy="false" />
                </binding>
            </customBinding>
        </bindings>
    </system.serviceModel>
    <system.webServer>
        <security>
            <authentication>
                <anonymousAuthentication enabled="true" />
                <windowsAuthentication enabled="false" />
            </authentication>
        </security>
    </system.webServer>
</configuration>

还有我的 client.config 文件：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.serviceModel>
        <client>
            <endpoint  address=""
                name="http"
                      binding="customBinding" bindingConfiguration="TLAPIServiceHttpBinding"
                      contract="AF.TipAndLeadAPI.ITipAndLeadAPIContract" />
        </client>
        <bindings>
            <customBinding>
                <binding name="TLAPIServiceHttpBinding">

                    <security authenticationMode="IssuedTokenOverTransport" allowInsecureTransport="true" />
                    <textMessageEncoding>
                        <readerQuotas maxStringContentLength="204857600" maxArrayLength="209715200" />
                    </textMessageEncoding>
                    <httpTransport maxReceivedMessageSize="216268800" authenticationScheme="Anonymous" useDefaultWebProxy="false" />
                </binding>
            </customBinding>
        </bindings>
    </system.serviceModel>
</configuration>

当我将 authenticationMode 更改为 IssuedTokenOverTransport 之类的内容时，我收到程序集不匹配错误。当我将其更改为带有证书的任何内容时，我会收到证书错误，所以我的猜测是，它与 authenticationMode 有关。

任何帮助将非常感激。
