# 什么是握手？
理解 WPA/WPA2 握手过程，并在授权评估中捕获它。
WPA/WPA2 握手是客户端与接入点之间的认证交换。它发生在客户端连接或重新连接到网络时。
捕获内容包含加密值。它不包含明文密码。
### 被动捕获
在评估期间，等待自然重连。将捕获范围限制在授权范围内的接入点和信道。
### 主动捕获
范围明确的测试网络可以使用主动技术来触发客户端重新连接。当接入点和客户端都明确在授权范围内时，目标去认证测试是一种选择。
### 后续验证
保留捕获文件，并记录其来源、日期和范围。然后在继续授权分析之前，验证该交换是否完整。

握手捕获证明了一次认证事件。它本身并不能证明密码强度。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://hacking-notes.jord4n.pro/zh/hacking-wifi/wpa-wpa2-psk-network-attacks/fundamentals/what-is-a-handshake.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
