# GenPMK でレインボーテーブルを作成する

GenPMK で事前計算済みの WPA/WPA2 キーデータベースを生成する。

GenPMKは、パスワードリストとネットワーク名から事前計算されたPMKデータベースを作成します。

各パスワードは、特定のESSIDに対するキーを1つ生成します。これらの値を事前に生成しておくと、後での検索が高速になります。

### ツールを確認する

{% code overflow="wrap" %}

```bash
genpmk
```

{% endcode %}

### データベースを生成する

パスワードリストとESSIDを使って `dic.genpmk` データベースを作成します:

{% code overflow="wrap" %}

```bash
genpmk -f passwords.txt -s jordan -d dic.genpmk
```

{% endcode %}

パラメータは次のとおりです:

* `-f passwords.txt` パスワード候補を取り込みます。
* `-s jordan` 対象のネットワーク名を設定します。
* `-d dic.genpmk` 出力データベースを指定します。

生成されたデータベースは同じESSIDで再利用できます。同じキーを再び計算する必要がなくなります。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/ja/hacking-wifi/wpa-wpa2-psk-network-attacks/precomputed-attacks/creating-a-rainbow-table-with-genpmk.md?ask=<question>&goal=<user_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.
