In case of a S3 multi-part operation each part is en/decrypted with the scheme shown in Figure 1. However, for each part a unique secret key is derived from the OEK and the part number using a PRF. So in case of multi-part not the OEK but the output of `PRF(OEK, part_id)` is used as secret key.

#### Cryptographic Primitives

//
// Therefore, an S3 implementation may encrypt an ETag before storing
// it. In this case, the stored ETag may not be a well-formed S3 ETag.
// For example, it can be larger due to a checksum added by authenticated
// encryption schemes. Such an ETag must be decrypted before sent to an
// S3 client.
//
// # S3 Clients
//
// There are many different S3 client implementations. Most of them

     * This method implements incremental crawling by comparing timestamps and checking document
     * expiration. It also handles special cases for different URL schemes (SMB, file, FTP).
     *
     * @param client the crawler client to use for accessing the URL
     * @param urlQueue the URL queue item containing the URL to check

## OAuth2 scopes 與 OpenAPI { #oauth2-scopes-and-openapi }

OAuth2 規格將「scopes」定義為以空白分隔的一串字串列表。

每個字串的內容可以有任意格式，但不應包含空白。

這些 scopes 代表「權限」。

在 OpenAPI（例如 API 文件）中，你可以定義「security schemes」。

當某個 security scheme 使用 OAuth2 時，你也可以宣告並使用 scopes。

每個「scope」就是一個（不含空白的）字串。

它們通常用來宣告特定的安全性權限，例如：

- `users:read` 或 `users:write` 是常見的例子。
- `instagram_basic` 是 Facebook / Instagram 使用的。

但如果你确实需要它，或者只是好奇，请继续阅读。

## OAuth2 作用域与 OpenAPI { #oauth2-scopes-and-openapi }

OAuth2 规范将“作用域”定义为由空格分隔的字符串列表。

这些字符串的内容可以是任意格式，但不应包含空格。

这些作用域表示“权限”。

在 OpenAPI（例如 API 文档）中，你可以定义“安全方案”（security schemes）。

当这些安全方案使用 OAuth2 时，你还可以声明并使用作用域。

每个“作用域”只是一个（不带空格的）字符串。

它们通常用于声明特定的安全权限，例如：

* 常见示例：`users:read` 或 `users:write`
* Facebook / Instagram 使用 `instagram_basic`
