js-md5 的简单使用
MD5（单项散列算法）的全称是Message-Digest Algorithm 5（信息-摘要算法），经MD2、MD3和MD4发展而来。
功能：1.输入任意长度的信息，经过处理，输出32位的信息；2.不同的输入得到的不同的结果（唯一性）；3.根据32位的输入结果不可能反推出输入的信息（不可逆）
用途：1.防止被篡改，发布文件时同时发布文件的MD5值，在对方收到文件后再次进行MD5计算，最终获得的结果一样，说明未被篡改；2.防止直接看到明文，这也是它最常见的用途，经常在某些页面点击提交后，密码就通过md5加密，直接由几位密码突然填满了密码框；3.作为数字签名。
1.安装js-md5
npm i js-md5
2.引入 & 挂载
import md5 from'js-md5';Vue.prototype.$md5Util = md5;
3.使用
this.$md5Util("请将我这段文字加密")
4.加密结果
// 加密结果：aa888a86dca6e9d5ae216c23070e8c47
5.js-md5 源码
md5中还包含hex/digest/array/arrayBuffer/base64 等多种使用方式，可通过下方js-md5的源码详细了解！
