Resource details
适合第一次遇到 URL 编码、想看看转换前后区别的人。这里只从一项简单文本转换开始，不需要搭服务器；编码不是加密，不能拿它保护密码。
Before you start
- Platforms
- 浏览器
- Content updated
- 准备能运行 JavaScript 的现代浏览器和一份不含隐私的测试材料；首次无需安装编程环境。
- 只试 hello%20world 这样的虚构文本，从单项 URL Decode 操作开始。
普通文本转换直接用官方网页，不需要下载服务端或 Node.js 开发环境。
Common pitfalls
- URL 编码不是加密，不能用来保护密码；转换前保留原始文本。
- 分享链接可能包含输入和配方，先去掉私人链接、访问令牌和个人信息。本站未实机转换测试，也未进行安全审计。

【你能完成的小目标】把 hello%20world 经过 URL Decode 转成 hello world，理解 %20 在这里代表空格。
【开始前准备】用浏览器打开 https://gchq.github.io/CyberChef/ ，只使用上面的虚构样本文字。不需要安装 Node.js，也不用下载 CyberChef-server。
【第一次尝试】在操作搜索框查找 URL Decode，将它拖入配方区，把 hello%20world 填进输入区，查看输出。再去掉这一项操作，观察输出如何变化；一次只学一种转换。
【遇到问题先看这里】不同编码和字符集会产生不同结果，不能把无法识别的内容当乱码直接覆盖原件。官方 README 说明核心处理在浏览器进行，并支持本地版本；分享链接可以包含输入与配方，复制前先检查，不要夹带访问令牌、私人链接或个人信息。这个练习不提供加密安全保证，也不负责判断不可信文件是否安全。

只用一个虚构例子理解 URL 编码，不研究复杂配方，也不接触真实账号和私人链接。
找到 URL Decode 操作
从上方的官方入口打开 CyberChef，在操作搜索框输入 URL Decode，将该操作拖到配方区。第一次只保留这一项操作，便于观察变化。
填入虚构文字观察输出
在输入区填 hello%20world，查看输出是否为 hello world。这里 %20 对应一个空格；不要把测试文本换成带密码或访问令牌的真实地址。
移除操作，再比较一次
从配方区去掉 URL Decode，观察输出如何变化，再加回去核对结果。确认只是编码与解码的区别，不把它当成加密或安全保护。
Expected output
能观察 hello%20world 经 URL Decode 变成 hello world，并说明这里的 %20 表示空格，编码并不是加密。
