我一直试图在
SSL Server Test @ SSL Labs上获得A.但是,我无法弄清楚如何通过“降级攻击预防”测试:
我在Linux Ubuntu 15.04(Vivid Vervet)上运行Jetty 9.3.0.v20150612和OpenJDK 8.
hristo@test:~$java -version openjdk version "1.8.0_45-internal" OpenJDK Runtime Environment (build 1.8.0_45-internal-b14) OpenJDK 64-Bit Server VM (build 25.45-b02,mixed mode)
我已阅读并按照Jetty’s SSL config documentation的说明进行操作,并尽力编辑相关的XML配置文件.无论我尝试什么,我仍然看到“不,TLS_FALLBACK_SCSV不支持”.
我通过运行此命令为Jetty启用了https和ssl模块:
$java -jar start.jar --add-to-startd=https,ssl INFO: ssl initialised in ${jetty.base}/start.d/ssl.ini INFO: https initialised in ${jetty.base}/start.d/https.ini INFO: Base directory was modified
我没有修改vanilla jetty.xml和jetty-https.xml,因为我不确定我需要在那里进行更改.这就是我对我的配置的看法:
start.ini
# added this to the bottom of start.ini # TLS configuration -Dhttps.protocols="TLSv1,TLSv1.1,TLSv1.2" -Djdk.tls.client.protocols="TLSv1,TLSv1.2" -Djdk.tls.ephemeralDHKeySize=2048
码头-SSL-的context.xml

我还缺少什么?我需要更多配置Jetty吗?我是否需要以某种方式配置Java 8?我需要修改一些特殊的Ubuntu配置吗?
它还没有在Java中实现 – 但它计划用于Java 9.
您可以按照#JDK-8061798进行更新.
