篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了怎样可以把微信的小程序加密相关的知识，希望对你有一定的参考价值。

1、下载MD5源文件(JS);
2、在小程序模块中使用require引入外部模块；也可以在index.html中直接全局引入md5.js文件。
因为源md5.js中没有队模块因为输出，如果使用require需要export，所以在md5.js中需要加入以下代码：

module.exports =
hexMD5: hex_md5, //需要输出的加密算法，我这边只写了我需要得两种
b64Md5: b64_md5,

在js文件中使用require引入md5:

const md5 = require('../../assets/js/md5/md5.js');

使用：

let b64 = md5.b64Md5(code); //code需要加密的数据

下面是我的文件结构：

md5.js 代码如下;
