How to implement css when onClick event occur in Reactjs

In ReactJS, you can implement CSS changes on an onClick event by using state to manage the CSS styles and then updating that state when the event occurs. Here's a step-by-step guide:

1.Create a React component:

import React, { useState } from "react";

import "./CSSViaOnClick.css";
function CSSviaOnClick() {
  const [isClicked, setIsClicked] = useState(false);

  const handleClick = () => {
    // Update the state when the button is clicked www.hackingtruth.in 
    setIsClicked(!isClicked);
  };

  // Define CSS classes based on the state www.kumaratuljaiswal.in
  const buttonClass = isClicked ? "clicked" : "unclicked";

  return (
    <div>
      <div className="main-div">
        <button onClick={handleClick} className={buttonClass}>
          Click me
        </button>
      </div>
    </div>
  );
}

export default CSSviaOnClick;

1. First of all we are written and import the two pkg first one is react and another one is css file.

2. In this example, we create a functional component App that uses the useState hook to manage the isClicked state. Initially, it's set to false.

3. We define a handleClick function that will be called when the button is clicked. Inside this function, we update the isClicked state using setIsClicked, toggling it between true and false with each click.

4. Based on the isClicked state, we determine the CSS class to apply to the button. In this case, we have two CSS classes: 'clicked' and 'unclicked', which you can define in your CSS or use CSS-in-JS libraries like styled-components.

5. Finally, we render the button with the onClick event handler and the appropriate CSS class.

Implement CSS

.main-div {

  left: 50%;
  top: 50%;
  text-transform: translate(-50%, -50%);
  position: absolute;
  border: 1px solid black;
  padding: 2px 6px 2px 6px;
  border-radius: 20%;
  font-weight: bold;


}



.clicked {

  color: red;
  letter-spacing: 2px;

}

.unclicked {
  color: blue;
}

Wheneven user click on button then event occur and css works.

What is CRUD?

CRUD is stands for "Create, Read, Update, and Delete".

These are the four basic operation for managing data in an application.

In HTTP we find four main methods that can perform processing on data that are defined in the REST architecture. This correspondence can also be done with CRUD.

GET     -> Retrieve
POST    -> Create
PUT     -> Update
Delete -> Delete

CRUD Operation

To Insert

Public class HomeController: Controller 

[HTTPPOST]

//controller is a class

public ActionResult InsertData(Students s)
 {
   ApplicationDb db = new ApplicationDb();
   
   db.Students.Add(s);
   db.SaveChanges();
   
   return view();
   
  }

To read

ApplicationDb db = new ApplicationDb();

var lst = db.Students.ToList();

List<Students> list = db.students.ToList();

foreach(var obj in list)
{
console.writeline (obj.StudentsId);
console.writeline (obj.StudentsName);
}

To Update

ApplicationDb db = new ApplicationDb();

Students s = db.Students.Where(x => x.StudentsId == items.StudentsId).SingleOrDefault();

//items is a model name

s.StudentsName = new StudentsName;

db.SaveChanges();

To Edit Single Update

Public Class HomeController: Controller

{

ApplicationDb db = new ApplicationDb();

Students s = db.Students.Where(x => x.StudentsId == StudentsId).SingleOrDefault();

return view(s);

}

To Delete

List <Students> s = db.studentsToList()


if(s!=null)
{
  foreach(var t in s)
   {  
     db.students.remove(t);
   }
  
  db.savechanges();
 
}

HTML Helper

HTML Helper is just a method that returns a HTML string. The string can represent any type of content that you want.

For example, you can use HTML Helpers to render standard HTML tags like HTML <input>, <button> and <img> tags etc.
You can also create your own HTML Helpers to render more complex content such as a menu strip or an HTML table for displaying database data.

Example:

HtmlHelper.ActionLink @Html.ActionLink(“Create New”, ”Create”, ”Home”)

In the above example, @Html is an object of HtmlHelper class & ActionLink() is the extension method

Html is a property of type HtmlHelper included in base class of razor view WebViewPage

HtmlHelper class generates html elements For example,

@Html.ActionList("Create New", "Create“, “Home”) would generate anchor tag <a href="/Home/Create">Create New</a>

HTML Element

TextBox @Html.TextBox("Textbox1", "val")

Output: <input id="Textbox1" name="Textbox1" type="text" value="val" />

TextArea @Html.TextArea("Textarea1", "val", 5, 15, null)

Output: <textarea cols="15" id="Textarea1" name="Textarea1" rows="5">val</textarea>

Password @Html.Password("Password1", "val")

Output: <input id="Password1" name="Password1" type="password" value="val" />

Hidden Field @Html.Hidden("Hidden1", "val")

Output: <input id="Hidden1" name="Hidden1" type="hidden" value="val" />

CheckBox @Html.CheckBox("Checkbox1", false)

Output: <input id="Checkbox1" name="Checkbox1" type="checkbox" value="true" /> <input name="myCheckbox" type="hidden" value="false" />

RadioButton @Html.RadioButton("Radiobutton1", "val", true)

Output: <input checked="checked" id="Radiobutton1" name="Radiobutton1" type="radio" value="val" />

Drop-down list @Html.DropDownList (“DropDownList1”, new SelectList(new [] {"Male", "Female"}))

Output: <select id="DropDownList1" name="DropDownList1"> <option>M</option> <option>F</option> </select>

Multiple-select Html.ListBox(“ListBox1”, new MultiSelectList(new [] {"Cricket", "Chess"}))

Output: <select id="ListBox1" multiple="multiple" name="ListBox1"> <option>Cricket</option> <option>Chess</option>

@Html.ActionLink("HomePage", Index.new{style='color:red');

Output: <a href="Index" style="color:red">HomePage</a>

@Html.DisplayName("Enter your username");

@HTMLDisplayNameFor(model => model.studentName);

Currently we are working on web 2 and we are excited about web 3 and then jack dorsey says hey we are coming up with web 5 that is correct but then why do we need web 3 and web 5 when we have web 2. web5 is here with web2+web3

Now think about this what is happening in the web 2 world now basically it provides you multiple services right so we have so many websites so many applications and they provide you some awesome services the only problem is for every different service you have to provide your information you share your personal information you share your post you share your photos you share your location and all this data is there with that particular website i mean that that is okay right not exactly you're not sure how they are using that data maybe they're using your data for marketing purpose they're using your data to sell to someone or they are using your data to influence you so that's one thing and again you might be thinking when you upload a photo on a website. web2

When you upload a post somewhere basically you own that data not exactly this company owns your data not just your post and photos your personal data as well so that's one issue the second issue is let's say if you are using a particular service maybe apple music so what you do is if you want to use that service you share information you share your email id phone number and all the details and then you are enjoying that particular service but what if you want to move to some other service again!! web3

You have to go to that particular website on an app you have to share your information then only you can access that particular service so basically if you want to switch you again have to share the information and this company they actually lock your data with them you can't even delete it and of course with the help of GDPR it may be possible but not in all the countries right so this company actually hold your information so can we do it this way can we just reverse it can we say hey let me hold my information. web2 tech

I have a box here in this box i will have my information and if you want to give that particular service you have to request for the service you have to request for the data i will give you data and then i'll be there of course when you don't have to share everything you just have to share that you have an identity and maybe a particular key and they can verify this is you what you're claiming to be right so that's the box.

I want that's the wallet that's the right word in the terms of web three we call it as a wallet which has your identity so that's why we were going for web3 right and that's where jack dorsey the founder of twitter says hey we have a better solution let's go for web 5 which is actually a combination of web 2 all the services and web 3 technology and that's your web 5 and this is actually built on bitcoin blockchain so basically web5 provides you with decentralized identity and the storage for your application to learn more let's go to that particular website so this is basically the company by jack dorsey a blockchain project company and it was formerly called as square and now we have a different name they're coming up with web five it's an extra decentralized web platform and you can see this is actually a combination of web 2 and web3. world wide web

If you want to learn more about it there's a amazing pdf available you can just explore that pdf in fact i will show you some introduction part as well now what they are providing you is first they are providing you with the wallets they are providing you with a decentralized web application uh in the web3 world we call them as dapps and they are also giving you decentralized web nodes the blockchain nodes actually if you explore this pdf which is an amazing pdf to go through so this is the same thing i've explained right so basically to access any a web you have to share information with each service but how about this can we just have one particular identity and we can share with multiple service and you don't even have to share information basically you will own your data and that's what i actually was talking about from a long time on this channel right basically we need privacy where you need to have a power where you need to have the hold on your own data.

image credit prototypr

So, we have talked about this this is actually web 2 and web3 which is creating web 5 and this is interesting so decentralized web application enables developers to write dapps or decentralized web application using the identifiers basically you'll be having your own identities and this identity is actually verifiable on the on the chain or on the network and important thing is they don't have a token here and don't think about the pricing of token or you know the inflation of tokens so that's a different thing.

We don't have any tokens here and it is decentralized web notes and they are combining everything to give you web five in fact this is just an introduction video of web5 i have not gone through the entire documentation how it will work how what kind of application you can build but this looks a promising start but again my bet is on web3 web5 is just an implementation just an idea so it's not a replacement for web3 in fact on twitter i saw this amazing tweet this is web one is scientists where in the driver's seat web 2 is techno entrepreneurs why the driver said web 3 is vcs because the entire web 3 is funded by vcs again it's a promising start but what about web five and jack dorsey said it is for the people uh people will be driving it and that looks promising so in future for sure we are moving from web 2 to web 3 it doesn't matter or i mean web 2 to web 3 or f5 so it doesn't matter whatever people are claiming about it's a scam or something you know maybe lack of knowledge but blockchain is there blockchain will be coming and then it will disrupt the entire ecosystem most of the companies are using private blockchains because they don't want to share the data with the world they want to use it for their own use cases maybe for supply chain maybe for hospital management or all those use cases and then for the consumer side.

What is DNS?

DNS (Domain Name System) provides a simple way for us to communicate with devices on the internet without remembering complex numbers. Much like every house has a unique address for sending mail directly to it, every computer on the internet has its own unique address to communicate with it called an IP address. An IP address looks like the following 104.21.56.127, 4 sets of digits ranging from 0 - 255 separated by a period. When you want to visit a website, it's not exactly convenient to remember this complicated set of numbers, and that's where DNS can help. So instead of rememberin104.21.56.127, you can remember hackingtruth.org instead. DNS in full details

Domain Hierarchy

TLD (Top-Level Domain)

A TLD is the most righthand part of a domain name. So, for example, the google.com TLD is .com. There are two types of TLD, gTLD (Generic Top Level) and ccTLD (Country Code Top Level Domain). Historically a gTLD was meant to tell the user the domain name's purpose; for example, a .com would be for commercial purposes, .org for an organisation, .edu for education and .gov for government. And a ccTLD was used for geographical purposes, for example, .ca for sites based in Canada, .co.uk for sites based in the United Kingdom and so on. Due to such demand, there is an influx of new gTLDs ranging from .online , .club , .website , .biz and so many more. For a full list of over 2000 TLDs click here.

Brought to you by Hacking Truth

Second-Level Domain

Taking google.com as an example, the .com part is the TLD, and google is the Second Level Domain. When registering a domain name, the second-level domain is limited to 63 characters + the TLD and can only use a-z 0-9 and hyphens (cannot start or end with hyphens or have consecutive hyphens).

Subdomain

A subdomain sits on the left-hand side of the Second-Level Domain using a period to separate it; for example, in the name admin.google.com the admin part is the subdomain. A subdomain name has the same creation restrictions as a Second-Level Domain, being limited to 63 characters and can only use a-z 0-9 and hyphens (cannot start or end with hyphens or have consecutive hyphens). You can use multiple subdomains split with periods to create longer names, such as jupiter.servers.google.com. But the maximum length must be kept below 253 characters. There is no limit to the number of subdomains you can create for your domain name.

Root Domain "."

TLD .edu .org .gov .com

Second Level Domain mit, hackingtruth, usa, google, nasa, army etc

1) What is the maximum length of a subdomain?

Ans :- 63

2) Which of the following characters cannot be used in a subdomain ( 3 b _ - )?

Ans :- _

3) What is the maximum length of a domain name?

Ans :- 253

4) What type of TLD is .co.uk?

Ans :- ccTLD

Record Types

DNS Record Types

DNS isn't just for websites though, and multiple types of DNS record exist. We'll go over some of the most common ones that you're likely to come across.

A Record

These records resolve to IPv4 addresses, for example 104.26.10.229

AAAA Record

These records resolve to IPv6 addresses, for example 2606:4700:20::681a:be5

CNAME Record

These records resolve to another domain name, for example, google's online shop has the subdomain name store.google.com which returns a CNAME record shops.shopify.com. Another DNS request would then be made to shops.shopify.com to work out the IP address.

MX Record

These records resolve to the address of the servers that handle the email for the domain you are querying, for example an MX record response for google.com would look something like alt1.aspmx.l.google.com. These records also come with a priority flag. This tells the client in which order to try the servers, this is perfect for if the main server goes down and email needs to be sent to a backup server.

TXT Record

TXT records are free text fields where any text-based data can be stored. TXT records have multiple uses, but some common ones can be to list servers that have the authority to send an email on behalf of the domain (this can help in the battle against spam and spoofed email). They can also be used to verify ownership of the domain name when signing up for third party services.
What type of record would be used to advise where to send email?

1) What type of record would be used to advise where to send email?

Ans :- MX

2) What type of record handles IPv6 addresses?

Ans :- AAAA

Making A Request

What happens when you make a DNS request

1) When you request a domain name, your computer first checks its local cache to see if you've previously looked up the address recently; if not, a request to your Recursive DNS Server will be made.

2) A Recursive DNS Server is usually provided by your ISP, but you can also choose your own. This server also has a local cache of recently looked up domain names. If a result is found locally, this is sent back to your computer, and your request ends here (this is common for popular and heavily requested services such as Google, Facebook, Twitter). If the request cannot be found locally, a journey begins to find the correct answer, starting with the internet's root DNS servers.

3) The root servers act as the DNS backbone of the internet; their job is to redirect you to the correct Top Level Domain Server, depending on your request. If, for example, you request www.google.com, the root server will recognise the Top Level Domain of .com and refer you to the correct TLD server that deals with .com addresses.

4) The TLD server holds records for where to find the authoritative server to answer the DNS request. The authoritative server is often also known as the nameserver for the domain. For example, the name server for google.com is kip.ns.cloudflare.com and uma.ns.cloudflare.com. You'll often find multiple nameservers for a domain name to act as a backup in case one goes down.

5) An authoritative DNS server is the server that is responsible for storing the DNS records for a particular domain name and where any updates to your domain name DNS records would be made. Depending on the record type, the DNS record is then sent back to the Recursive DNS Server, where a local copy will be cached for future requests and then relayed back to the original client that made the request. DNS records all come with a TTL (Time To Live) value. This value is a number represented in seconds that the response should be saved for locally until you have to look it up again. Caching saves on having to make a DNS request every time you communicate with a server.

1) What field specifies how long a DNS record should be cached for?

Ans :- TTL

2) What type of DNS Server is usually provided by your ISP?

Ans :- recursive

3) What type of server holds all the records for a domain?

Ans :- authoritative

What is Port Forwarding | use of ngrok | Access localhost website from outside network

In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall. This technique is most commonly used to make services on a host residing on a protected or masqueraded (internal) network available to hosts on the opposite side of the gateway (external network), by remapping the destination IP address and port number of the communication to an internal host.

Port forwarding allows remote computers (for example, computers on the Internet) to connect to a specific computer or service within a private local-area network (LAN).[3]

In a typical residential network, nodes obtain Internet access through a DSL or cable modem connected to a router or network address translator (NAT/NAPT). Hosts on the private network are connected to an Ethernet switch or communicate via a wireless LAN. The NAT device's external interface is configured with a public IP address. The computers behind the router, on the other hand, are invisible to hosts on the Internet as they each communicate only with a private IP address. What is Port Forwarding ? use of ngrok ? Access localhost website from outside network

When configuring port forwarding, the network administrator sets aside one port number on the gateway for the exclusive use of communicating with a service in the private network, located on a specific host. External hosts must know this port number and the address of the gateway to communicate with the network-internal service. Often, the port numbers of well-known Internet services, such as port number 80 for web services (HTTP), are used in port forwarding, so that common Internet services may be implemented on hosts within private networks.

Typical applications include the following:

Running a public HTTP server within a private LAN
Permitting Secure Shell access to a host on the private LAN from the Internet
Permitting FTP access to a host on a private LAN from the Internet
Running a publicly available game server within a private LAN

Administrators configure port forwarding in the gateway's operating system. In Linux kernels, this is achieved by packet filter rules in the iptables or netfilter kernel components. BSD and macOS operating systems prior to Yosemite (OS 10.10.X) implement it in the Ipfirewall (ipfw) module while macOS operating systems beginning with Yosemite implement it in the Packet Filter (pf) module.

When used on gateway devices, a port forward may be implemented with a single rule to translate the destination address and port. (On Linux kernels, this is DNAT rule). The source address and port are, in this case, left unchanged. When used on machines that are not the default gateway of the network, the source address must be changed to be the address of the translating machine, or packets will bypass the translator and the connection will fail.

When a port forward is implemented by a proxy process (such as on application layer firewalls, SOCKS based firewalls, or via TCP circuit proxies), then no packets are actually translated, only data is proxied. This usually results in the source address (and port number) being changed to that of the proxy machine.

Usually only one of the private hosts can use a specific forwarded port at one time, but configuration is sometimes possible to differentiate access by the originating host's source address.

Unix-like operating systems sometimes use port forwarding where port numbers smaller than 1024 can only be created by software running as the root user. Running with superuser privileges (in order to bind the port) may be a security risk to the host, therefore port forwarding is used to redirect a low-numbered port to another high-numbered port, so that application software may execute as a common operating system user with reduced privileges.

The Universal Plug and Play protocol (UPnP) provides a feature to automatically install instances of port forwarding in residential Internet gateways. UPnP defines the Internet Gateway Device Protocol (IGD) which is a network service by which an Internet gateway advertises its presence on a private network via the Simple Service Discovery Protocol (SSDP). An application that provides an Internet-based service may discover such gateways and use the UPnP IGD protocol to reserve a port number on the gateway and cause the gateway to forward packets to its listening socket.

Types of port forwarding

Port forwarding can be divided into the following specific types: local, remote, and dynamic port forwarding.

Local port forwarding

Local port forwarding is the most common type of port forwarding. It is used to let a user connect from the local computer to another server, i.e. forward data securely from another client application running on the same computer as a Secure Shell (SSH) client. By using local port forwarding, firewalls that block certain web pages are able to be bypassed.

Remote port forwarding

This form of port forwarding enables applications on the server side of a Secure Shell (SSH) connection to access services residing on the SSH's client side.[8] In addition to SSH, there are proprietary tunnelling schemes that utilize remote port forwarding for the same general purpose.[9] In other words, remote port forwarding lets users connect from the server side of a tunnel, SSH or another, to a remote network service located at the tunnel's client side.

To use remote port forwarding, the address of the destination server (on the tunnel's client side) and two port numbers must be known. The port numbers chosen depend on which application is to be used.

Remote port forwarding allows other computers to access applications hosted on remote servers. Two examples:

An employee of a company hosts an FTP server at their own home and wants to give access to the FTP service to employees using computers in the workplace. In order to do this, an employee can set up remote port forwarding through SSH on the company's internal computers by including their FTP server’s address and using the correct port numbers for FTP (standard FTP port is TCP/21).

Opening remote desktop sessions is a common use of remote port forwarding. Through SSH, this can be accomplished by opening the virtual network computing port (5900) and including the destination computer’s address.

Dynamic port forwarding

Dynamic port forwarding (DPF) is an on-demand method of traversing a firewall or NAT through the use of firewall pinholes. The goal is to enable clients to connect securely to a trusted server that acts as an intermediary for the purpose of sending/receiving data to one or many destination servers.[11]

DPF can be implemented by setting up a local application, such as SSH, as a SOCKS proxy server, which can be used to process data transmissions through the network or over the Internet. Programs, such as web browsers, must be configured individually to direct traffic through the proxy, which acts as a secure tunnel to another server. Once the proxy is no longer needed, the programs must be reconfigured to their original settings. Because of the manual requirements of DPF, it is not often used.

Once the connection is established, DPF can be used to provide additional security for a user connected to an untrusted network. Since data must pass through the secure tunnel to another server before being forwarded to its original destination, the user is protected from packet sniffing that may occur on the LAN.

DPF is a powerful tool with many uses; for example, a user connected to the Internet through a coffee shop, hotel, or otherwise minimally secure network may wish to use DPF as a way of protecting data. DPF can also be used to bypass firewalls that restrict access to outside websites, such as in corporate networks.

How to use Ngrok for Access outside Network ?

1) first we need a localhost server such as hosting provider or need a web address to access the outside network ( For eg Ngrok )

ngrok.com

Spend more time programming. One command for an instant, secure URL to your localhost server through any NAT or firewall.

2) Signup or login to ngrok and go to with download option for downloading a ngrok server ( application )

https://ngrok.com/download

3) First, download the ngrok client, a single binary with zero run-time dependencies. you can downloa for MAC OS X, Windows, Mac (32bit), Windows (32-bit), Linux (ARM), Linux (ARM64), Linux (32-bit), FreeBSD (64-Bit), FreeBSD (32-bit)...

4) On Linux or OSX you can unzip ngrok from a terminal with the following command. On Windows, just double click ngrok.zip.

$ unzip /path/to/ngrok.zip

Most people like to keep ngrok in their primary user folder or set an alias for easy command-line access.

5) Try it out by running it from the command line:

./ngrok help

6) To start a HTTP tunnel on port 80, run this next:

./ngrok http 80

OR

ngrok http -subdomain=baz 8080

OR

ngrok http foo.dev:80

OR

ngrok http https://localhost

OR

ngrok tcp 22

How To Access website from Outside Network ?

Type the following command and press enter :-

1) serivce apache2 start

otherwise i have already download and install external apache server ( XAMPP Server )

For chech a service status , it's a start or not

service apache2 start

then we have ready to access our localhost website via inside and outside network ( internet )

Now, we have to copy a ngrok's link

https://ab5ac26e3592.ngrok.io

Then access

Through Mobile

One of the easiest way for cyber criminals to hack into internet users’ accounts is to crack their
passwords. Quite often people — out of ignorance or laziness — tend to keep passwords that are easy to guess.

One of the easiest way for cyber criminals to hack into internet users’ accounts is to crack their
passwords. Quite often people — out of ignorance or laziness — tend to keep passwords that are easy to guess. However, what they forget is that these passwords are also easy to hack and crack. Top 30 worst passwords in 2020 According to a recent research by cyber security firm ImmuniWeb, out of 21 million “credentials belonging to Fortune 500 companies, about 16 million were compromised” during the last one year. The research firm further found that just 4.9 million out the 21 million passwords were unique. In other words, a vast chunk of them were easy to hack. Of these millions of passwords, there are 32 that are most-commonly used. These 32 passwords appear in almost all hacker lists across industries. So, here are these 32 passwords that you should stop using right now if you want to protect your account from hackers. Top 30 worst passwords in 2019

"iloveyou" just missed out on the top 10, while "monkey" and "dragon" made surprise appearances in the top 20. Plenty of users also used passwords as an opportunity to employ a colorful array of swear words.

Popular brand names were also chosen, such as cocacola, snickers, mercedes, skittles, mustang, and playboy. MySpace and LinkedIn were also common choices, alarmingly, to secure accounts on those sites.

Bands and movie references were often used, with Spiderman, superman, starwars, and pokemon all common choices as were expressions of frustration – a**hole, bull****, and f***you were often chosen.

What Makes a Good Password?

A good password will not be in the dictionary, will not use sequential numbers or be created by walking fingers along a keyboard. Brand names and locations should also be avoided. Passwords should be a minimum of 8 characters and should be unique – never used before by the user, and never reused on a different platform.

Passwords should include at least one capital letter, lowercase letter, symbol and number. If all lowercase letters are used, each letter in the password could be one of 26 letters. Add in capitals and the possible options double to 52. There are 10 digits, increasing the options to 62, and let’s say 32 special characters, bringing the total up to 94 options. With so many options and possible combinations, randomly generated passwords are particularly difficult to guess. However, randomly generated passwords are also particularly difficult to remember.

Recently, that problem has been recognized by the National Institute of Standards and Technology (NIST), which has revised its advice on passwords (See special publication 800-63B).

While the use of random strings of characters and symbols makes passwords particularly difficult to guess and more resilient to hackers’ brute force password guessing tactics, end users have trouble remembering their passwords and that leads to particularly risky behaviors such as writing the password down or storing it in a browser.
