我发现我的嵌入式Jetty 9.1.5服务器上存在一个SWEET32。为了解决这个问题，我将这些行添加到jetty.xml中：

除此TLS_RSA_WITH_3DES_EDE_CBC_SHA外，其他所有3DES密码均消失。太奇怪了！
如何摆脱这种密码？
提前致谢。
最佳答案
使用最新的稳定版Jetty，您可以请求服务器转储，并查看已启用/已禁用密码的列表，以及（最重要的是！）已禁用密码的位置。

您会很快发现，Jetty配置中默认已经禁用了您专门呼出的密码，而正在运行的JRE已禁用了其他密码。
至于配置密码列表，您可以将SslContextFactory配置为具有所需的排除项。有很多方法可以配置它，最好是从...的官方文档中选择最适合您需要的技术。

关于ssl - 为Jetty服务器禁用TLS_RSA_WITH_3DES_EDE_CBC_SHA，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/42182101/
