# パスワード（およびハッシュ化）によるOAuth2、JWTトークンによるBearer

これでセキュリティの流れが全てわかったので、<abbr title="JSON Web Tokens">JWT</abbr>トークンと安全なパスワードのハッシュ化を使用して、実際にアプリケーションを安全にしてみましょう。

このコードは、アプリケーションで実際に使用したり、パスワードハッシュをデータベースに保存するといった用途に利用できます。

本章では、前章の続きから始めて、コードをアップデートしていきます。

## JWT について

JWTとは「JSON Web Tokens」の略称です。

JSONオブジェクトをスペースのない長く密集した文字列で表現したトークンの仕様です。例えば次のようになります：

```

.Values.metrics.serviceMonitor.relabelConfigs }} {{ toYaml .Values.metrics.serviceMonitor.relabelConfigs | indent 6 }} {{- end }} {{- if not .Values.metrics.serviceMonitor.public }} bearerTokenSecret: name: {{ template "minio.fullname" . }}-prometheus key: token {{- end }} namespaceSelector: matchNames: - {{ .Release.Namespace | quote }} selector: matchLabels: app: {{ include "minio.name" . }} release: {{ .Release.Name }} monitoring: "true" {{- end }} {{- if .Values.metrics.serviceMonitor.enabled }} --- apiVersion:...

			buf.Write(blk[:])
			for _, c := range blk {
				if c == '\n' {
					cntNewline++
				}
			}
		}
		return nil
	}

	// nextToken gets the next token delimited by a newline. This assumes that
	// at least one newline exists in the buffer.
	nextToken := func() string {
		cntNewline--
		tok, _ := buf.ReadString('\n')
		return strings.TrimRight(tok, "\n")
	}

* Some components like kube-dns and kube-proxy could fail to load the service account token when started within a pod. Properly handle empty configurations to try loading the service account config.
