# Tools 工具预览包

目标：实现在线预览，加密、编码、转换等工具，功能点如下：

- MD5 信息-摘要算法

- SM4/SM3/SM2国密

- DES

- AES

- BASE64

- URI 编码

- JSON格式化

- 图片验证码(跨平台)

- 时间戳

- M3U8文件在线预览 [http://101.34.7.82/tools/#/m3u8](http://101.34.7.82/tools/#/m3u8)

## 预览地址

- UI [https://igeekfan.cn/tools/#/](https://igeekfan.cn/tools/#/)

- API [https://igeekfan.cn/tools_api/swagger/index.html](https://igeekfan.cn/tools_api/swagger/index.html)

## 示例 DES

- JAVA+C# 相同的DES 加密/解密

### C# 调用

```csharp

    string password = "12345678";

    string sourceString = "{'idcard':'330781198509077211','date':'2021-11-11 19:04'}";

    Console.WriteLine("源字符串：" + sourceString);

    var c = DESUtil.Encrypt(sourceString, password);

    //加密：3tL0BBKZyUpIfO+XJKL1VoeQhEWc0enGG8R//RPBJQCiykspXEBmvabp8yrWTBv+QUL62K7dUL+vbpYV/PwZvw==

    Console.WriteLine("加密：" + c);

    c = HttpUtility.UrlEncode(c);

    Console.WriteLine("url编码：" + c);

    Console.WriteLine("================");

    c = HttpUtility.UrlDecode(c);

    Console.WriteLine("url解码：" + c);

    try

    {

        c = DESUtil.Decrypt(c, password);

        Console.WriteLine("url解密：" + c);

        var user = JsonConvert.DeserializeObject(c);

        Console.WriteLine("反序列化\n日期：" + user.date);

        Console.WriteLine("身份证号：" + user.idcard);

    }

    catch (Exception e)

    {

        Console.WriteLine("无法解密：" + e.StackTrace + e.Message);

    }

    Console.WriteLine("------over--------");

    Console.ReadLine();

```

### JAVA调用

```java

    String password="12345678";

    String den = DESUtil.encrypt("{'idcard':'330781198509077211','date':'2021-11-11 19:04'}",password);

    System.out.println("加密:"+den);

    String CHARSET="utf-8";

    String encodeStr= URLEncoder.encode(den,CHARSET);

    System.out.println("url编码:"+den);

    String decodeUrl=URLDecoder.decode(encodeStr,CHARSET);

    System.out.println("url解码："+decodeUrl);

    String ert = DESUtil.decrypt(decodeUrl,password);

    System.out.println("url解密："+ert);

```
