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‘);
