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
