c# - HttpWebRequest 中的 SSL 重新协商 (SEC_I_RENEGOTIATE) 问题并且没有保持事件状态

标签 c# ssl https

我们使用 HttpWebRequest 进行 REST 交互，通过 HTTPS，启用了 keep-alive。这可行，但在服务器端(Apache)我们经常遇到这样的错误:
“重新协商握手失败:客户不接受!？”

(没有详细记录的更多信息)

在客户端，在 System.Net 跟踪中，我们有以下消息:
解密返回 SEC_I_RENEGOTIATE。
(下面更完整的日志)。
此外，TCP 连接没有被重复使用(keep-alive 无法正常工作，尽管当我在没有 SSL 的情况下进行测试时它运行良好)。
这大大减慢了与 REST api 的交互。

HttpWebRequest 配置为启用保持事件状态、客户端证书、服务器证书回调。我已经测试了 ServicePointManager.SecurityProtocol SSL3 和 TLS。

客户端在 win XP SP3 上的 .NET Framework 3.5 SP1 上运行。

任何诊断和纠正此问题的帮助将不胜感激!谢谢

最佳答案

您需要在客户端处理 SEC_I_RENEGOTIATE 。当 DecryptMessage 返回 SEC_I_RENEGOTIATE 时，您需要再次进行握手循环。
微软Documentation会帮你解决的。您还可以在 github 中找到示例代码。
