我正在通过Tomcat 8 + Java 8构建B2B服务。 但是我的一位客户无法使用SSL连接到我的服务。 “-Djavax.net.debug = SSL”,我看到错误消息:如何在SSL握手期间解决“不共享密码套件”?

如何解决错误 添加SSL调试参数后?

以下是我的经验分享解决问题。

  1. 启用SSL调试参数“-Djavax.net.debug = SSL”,发现错误是“没有共同的密码套件”

  2. google搜索一些网页后,我安装了“Java加密扩展(JCE)无限强度管辖权“,http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html,它在JVM级别添加了一些密码算法,例如:TLS_RSA_WITH_AES_256_CBC_SHA,但它没有解决问题。 PS。 Ciphers.java是一个有用的代码,它可以显示JVM级别的可用密码套件。

  3. 我捕获了网络数据包并在wireshark中分析,它显示客户端发送ClientHello后,我的服务器立即断开连接。

  4. 由于我的客户无法用我的测试,我必须自己重现问题以加快故障排除过程。然后我找到了代码SslPoke.java并对其进行了修改。它可以通过使用TLS版本或密码套件的不同组合来模拟客户端的请求。我可以自己模拟相同的错误日志,它帮助了很多。

  5. 然后,再次谷歌,我发现我可以在Tomcat的server.xml中指定的密码套件,例如:

<Connector port="${https.port}" SSLEnabled="true" scheme="https" sslProtocol="TLS" ciphers="TLS_RSA_WITH_AES_256_CBC_SHA256... " />

我增加了配置,通过SslPoke测试并通过的情况下关闭。

希望这种体验能够帮助其他面临同样问题的人。 不要忘记检查JVM/Web容器/应用程序服务器中的密码套件配置... 以下代码也非常有用,感谢提供它们的专家。

最好的问候,
