# PuTTY キーを OpenSSH に変換する
PPK のエクスポート、秘密鍵形式の変更、SSH 認証、鍵ベースアクセスのトラブルシューティングを含む PuTTY から OpenSSH への鍵変換ガイド。
### PuTTYキーをOpenSSH形式に変換
ここではPuTTYキーをOpenSSH形式に変換します:
```bash
puttygen key.ppk -O private-openssh -o id_rsa
```
次に、秘密鍵の権限が適切であることを確認します:
```bash
chmod 600 id_rsa
```

## 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/post-exploitation/convert-putty-key-to-openssh.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.
