# 図解について

この本で使用するほとんどの図解では、同じ図を使用する。矢印については、2つの矢印に囲まれているオブジェクトは、その2つの要素から作られるという意味で使っている。

たとえば以下の図解で言えば、このように読む。

`Key + Password = EncryptedKey`\
`EncryptedKey + Password = Key`

![](/files/-LL8tTI0d7IMki_gdoRK)

コードも理解するために良い方法なのだが、時としてたくさんの言葉を使うよりも図のほうが簡単に表せる。（心配しないでいただきたいのだが、もちろんコードも紹介する。）

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://programmingblockchain.gitbook.io/programmingblockchain-japanese/introduction/diagrams.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
