# 使用彩虹表进行 Cowpatty 破解
使用 Cowpatty 配合预计算的 GenPMK 数据库和捕获到的握手。
在创建 GenPMK 数据库后，Cowpatty 可以使用它来检查捕获到的握手包。
数据库和捕获文件必须使用相同的网络名称。这里，ESSID 是 `jordan`.
### 运行查找
使用预先计算的 `dic.genpmk` 数据库与捕获文件：
{% code overflow="wrap" %}
```bash
cowpatty -d dic.genpmk -r Capture-01.cap -s jordan
```
{% endcode %}
参数如下：
* `-d dic.genpmk` 选择 GenPMK 数据库。
* `-r Capture-01.cap` 提供捕获到的握手包。
* `-s jordan` 设置目标网络名称。
Cowpatty 在不到 0.03 秒内找到了密码。查找速率为每秒 445,106 个密码。
预先计算的值使查找速度快得多。在此步骤中，它们避免了对每个候选项重新计算。

## 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/precomputed-attacks/cowpatty-cracking-against-a-rainbow-table.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.
