# 使用 GenPMK 创建彩虹表
使用 GenPMK 生成预计算的 WPA/WPA2 密钥数据库。
GenPMK 会根据密码列表和网络名称创建一个预计算的 PMK 数据库。
每个密码都会为一个特定的 ESSID 生成一个密钥。提前生成这些值可以加快后续查找速度。
### 查看该工具
{% code overflow="wrap" %}
```bash
genpmk
```
{% endcode %}
### 生成数据库
使用密码列表和 ESSID 来创建 `dic.genpmk` 数据库：
{% code overflow="wrap" %}
```bash
genpmk -f passwords.txt -s jordan -d dic.genpmk
```
{% endcode %}
参数如下：
* `-f passwords.txt` 导入密码候选项。
* `-s jordan` 设置目标网络名称。
* `-d dic.genpmk` 指定输出数据库。
生成的数据库可以在相同的 ESSID 上重复使用。它避免了再次计算相同的密钥。

## 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/creating-a-rainbow-table-with-genpmk.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.
