java - 实施 IPSEC 协议

Question

我想IPSEC在java中实现一个协议。我想知道如何创建我们自己的协议。以及如何将这个协议嵌入到数据包中。

请提供一些代码示例，以便于理解。

Answer 1

IPSec is a internet layer protocol, not an application layer protocol. It works by encrypting/securing each network packet and as such runs at the network card level, usually by an OS provided driver which makes its use transparent to any applications.

It is not something you implement in your own code, instead if you wanted application level security you'd look at TLS/SSL or something more specific to your communications protocol.

Answer 2

IPSec 不能在 JAVA 中实现。Java 需要虚拟机。我们需要可以直接在机器上运行的代码。
