ssh-korerorero wahanga 2

Kia ora, Habr. Koinei te tuhinga tuarua o te raupapa ssh-korerorero.

Ka aha tatou:

• Me taapiri te kaha ki te hanga i o ake mahi hoahoa
• Me taapiri te tautoko tohu
• Me taapiri te tautoko bot
• Whakanuia te haumarutanga kupuhipa (hash me te tote)
  Aroha mai, engari karekau he tukunga o nga konae

Nga ahuatanga hoahoa ritenga

I tenei wa, ka tautokohia nga mahi hoahoa e whai ake nei:

• @color
• @bold
• @underline
• @hex
• @box
  Engari he pai te taapiri i te kaha ki te hanga i o ake mahi:
  Ka penapena nga mahi katoa ki roto объекте под названием methods
  Na ka nui ki te hanga i tetahi mahi registerMethod:

// parserExec.js at end
module.exports.registerMethod  =  function(name, func) {
  methods[name] =  func
}

Me whakahoki ano e koe tenei tikanga i muri i te hanga i te tūmau

// index.js at require part
const { registerMethod } = require('./parserExec')

// index.js at end
module.exports.registerMethod  =  registerMethod

Inaianei, i te wa e hanga ana he tūmau, ka taea e tatou te rehita tikanga whakahōputu. Tauira:

const  chat  =  require('.')
const { formatNick } =  require('./format')

chat({})

chat.registerMethod('hello', function(p, name){
  return  'Hi, '  +  formatNick(name) +  '!'
})

Tautoko Markdown

He tino watea a Markdown, na me taapiri ma te whakamahi kua tohua te mutunga

// format.js near require
const marked = require('marked');
const TerminalRenderer = require('marked-terminal');

marked.setOptions({
  renderer: new TerminalRenderer()
});

// format.js line 23
message = marked(message)

Papatipu

Me pehea te mahi

let writeBotBob = chat.registerBot({
  name: 'botBob',

  onConnect(nick, write){
    write('@hello{' + nick + '}')
  },

  onDisconnect(nick, write){},

  onMessage(nick, message, write) {
    if(message == 'botBob!') write('I'm here')
  },

  onCommand(command, write) {
    write('Doing ' + command)
  }
})

onCommand ka taea te karanga ma te whakamahi @bot(botBob){Command}

Ko nga mea katoa mo te mahi me nga bots kua whakaahuahia i roto i te konae:

let bots = []; // Все боты

let onWrite = () => {}; 

function getWrite(bot) { // Генерирует метод отправки сообщения для бота
  return msg => {
    onWrite(bot.name, msg);
  };
}

module.exports.message = function message(nick, message) { // index.js выполнит эту функцию после отправки сообщения
  bots.forEach(bot => {
    try {
      bot.onMessage(nick, message, getWrite(bot));
    } catch (e) {
      console.error(e);
    }
  });
};

module.exports.connect = function message(nick) { // При соединении
  bots.forEach(bot => {
    try {
      bot.onConnect(nick, getWrite(bot));
    } catch (e) {
      console.error(e);
    }
  });
};

module.exports.disConnect = function message(nick) { // При отсоединении
  bots.forEach(bot => {
    try {
      bot.onDisconnect(nick, message, getWrite(bot));
    } catch (e) {
      console.error(e);
    }
  });
};

module.exports.command = function message(name, message) { // При выполнении команды
  bots.forEach(bot => {
    if (bot.name == name) {
      try {
        bot.onCommand(message, getWrite(bot));
      } catch (e) {
        console.error(e);
      }
    }
  });
};

module.exports.registerBot = function(bot) {
  bots.push(bot);
  return  getWrite(bot)
};

module.exports.onMessage = func => {
  onWrite = func;
};

He aha ka taea e koe me nga potae:

• Aroturuki utaina
• tohatoha
• Papa mahi

Hash me te tote

He aha te take e kore ai nga taviri ssh? Na te mea ka rereke nga taviri ssh i runga i nga taputapu rereke
Me hanga he konae hei tirotiro me te hanga kupuhipa

// crypto.js
const crypto = require('crypto');

function genRandomString(length) {
  return crypto
    .randomBytes(Math.ceil(length / 2))
    .toString('hex')
    .slice(0, length);
}

function sha512(password, salt){
  const hash = crypto.createHmac('sha512', salt); /** Hashing algorithm sha512 */
  hash.update(password);
  const value = hash.digest('hex');
  return value
};

function checkPass(pass, obj){
  return obj.password == sha512(pass, obj.salt)
}

function encodePass(pass){
  const salt = genRandomString(16)
  return JSON.stringify({
    salt,
    password: sha512(pass, salt)
  })
}

module.exports.encodePass = encodePass
module.exports.checkPass = checkPass

He tuhinga mo te tote me te hashing te kupuhipa

// To generate password run node ./encryptPassword password
const { encodePass } =require('./crypto')
console.log(encodePass(process.argv[2]))

Ka whakahōu mātou i roto i users.json a hei utu mo te whakatairite i roto i te lobby.js ka whakamahia e matou te checkPassword

Ko te hua

Ko te mutunga, he korero korero ma te ssh me nga kaha hoahoa me nga potae.
Te putunga whakamutunga
