nodejs进阶：密码加盐：随机盐值

var crypto = require(‘crypto‘);function getRandomSalt(){ ???return Math.random().toString().slice(2, 5);}function cryptPwd(password, salt) { ???// 密码“加盐” ???var saltPassword = password + ‘:‘ + salt; ???console.log(‘原始密码：%s‘, password); ???console.log(‘加盐后的密码：%s‘, saltPassword); ???// 加盐密码的md5值 ???var md5 = crypto.createHash(‘md5‘); ???var result = md5.update(saltPassword).digest(‘hex‘); ???console.log(‘加盐密码的md5值：%s‘, result);}var password = ‘123456‘;var salt=‘abc‘;cryptPwd(password, getRandomSalt());cryptPwd(password, getRandomSalt());cryptPwd(password,‘abc‘);
