在服务器端启用"-Djavax.net.debug = ssl:handshake"时"忽略不支持的密码套件"消息

Question

我已经实现了SSLServerSocket,当我启动.jar文件时可以选择-Djavax.net.debug=ssl:handshake调试安全握手,我也得到这些消息(在建立一些安全连接之前):

...

...

这是什么意思？也许我在Java中缺少256位安全性(替换Java目录中的一些文件)？

创建后,SSLServerSocket我启用了安全协议,如:

socket.setEnabledProtocols(new String[]{"TLSv1","TLSv1.1","TLSv1.2","SSLv2Hello"});

也许我应该启用这些上面的密码套件？

除了这些密码套件,一切都很好.

编辑:

是的,@ Boris the Spider是对的:安装 Oracle无限强度策略文件后,警告不再可见.

Answer 1

所以答案是你需要Oracle无限强度的策略文件
