Die einzige strenge Regel für Überschriften ist, dass das LLM den Hash-Teil in geschweiften Klammern unverändert lässt, damit Links nicht kaputtgehen.

### Headings

Every Markdown heading in the English text (all levels) ends with a part inside curly brackets. This part denotes the hash of this heading, which is used in links to this heading. In translations, translate the heading, but do not translate this hash part, so that links do not break.

Examples of how to translate a heading:

    Source (English):

        «««

                                && Objects.equals(this.children, that.children());
            }

            @Override
            public int hashCode() {
                return Objects.hash(name, value, attributes, children);
            }

            @Override
            public String toString() {
                try {
                    StringWriter writer = new StringWriter();

Olá novamente.

A única regra rígida para títulos é que o LLM deixe a parte do hash dentro de chaves inalterada, o que garante que os links não quebrem.

# OAuth2 实现密码哈希与 Bearer  JWT 令牌验证

至此，我们已经编写了所有安全流，本章学习如何使用 <abbr title="JSON Web Tokens">JWT</abbr> 令牌（Token）和安全密码哈希（Hash）实现真正的安全机制。

本章的示例代码真正实现了在应用的数据库中保存哈希密码等功能。

接下来，我们紧接上一章，继续完善安全机制。

## JWT 简介

JWT 即**JSON 网络令牌**（JSON Web Tokens）。

JWT 是一种将 JSON 对象编码为没有空格，且难以理解的长字符串的标准。JWT 的内容如下所示：

```

Bei umfangreichen Responses ist die direkte Rückgabe einer `Response` wesentlich schneller als ein <abbr title="Dictionary – Zuordnungstabelle: In anderen Sprachen auch Hash, Map, Objekt, Assoziatives Array genannt">Dictionary</abbr> zurückzugeben.

// along with this program.  If not, see <http://www.gnu.org/licenses/>.

Para o OAuth2, eles são apenas strings.
