小程序如何使用md5
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app.js中直接全局引入md5.js文件。
因为源md5.js中没有对模块进行输出，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:
推荐学习：小程序开发
const md5 = require( #39;../../assets/js/md5/md5.js #39;);
使用：
let b64 = md5.b64Md5(code); //code需要加密的数据
下面是我的文件结构：
