Hey guys,
I got bored and was testing other things and since I came across my own way and more safer way I decided to post my original code I written.
So all we need, is a textbox and a button and your site/local server or whatever.
What you need to do:
Create a text document and in this document we place our CPU Key's in. And then the app reads the file and checks if the input of textbox matches.
You will need to be using:
Then for the button (Which will log you in) you want to create the string for the CPU Key and check for an available network (Checking internet). Like this:
Now, we are still on the button. We want to download our .txt file with the CPU key of a user inside it. To do this we use the WebClient (System.Web) usage.
So we use the Connection bool to do this. So:
This checks if you can connect to internet and if you can it downloads the txt file.
But we should always create and else statement to notify the user that they can't connect to internet. So this is simple, we use the else {} with a popup (MessageBox).
If you don't know how then here:
Now we want to read the txt file and check if the CPU key the user enters in the textbox exists. So we simply use our string "strings" to see if the cpuKey entered in textbox is contained in the txt file and if it is, we say CPU Authed! or something.
And yet again we need to notify the user if the CPU Key isn't there. So we simply do:
This is great but not secure and can easily be cracked. That's why I used another method checking a database (But my app is confused so it should be safe).
Credit: Me (For coding this)
AWL: For being awesome and testing.
Have fun ^_^

Create a text document and in this document we place our CPU Key's in. And then the app reads the file and checks if the input of textbox matches.
You will need to be using:
using System.Net;
using System.Net.NetworkInformation;
using System.Web;
Then for the button (Which will log you in) you want to create the string for the CPU Key and check for an available network (Checking internet). Like this:
bool Connection = NetworkInterface.GetIsNetworkAvailable();
string cpuKey = string.Empty;
WebClient webClient = new WebClient();
string strings = null;
Now, we are still on the button. We want to download our .txt file with the CPU key of a user inside it. To do this we use the WebClient (System.Web) usage.
So we use the Connection bool to do this. So:
if (Connection == true)
{
strings = webClient.DownloadString("http://example.com/cpukeys.txt");
webClient.Dispose();
}
This checks if you can connect to internet and if you can it downloads the txt file.
But we should always create and else statement to notify the user that they can't connect to internet. So this is simple, we use the else {} with a popup (MessageBox).
If you don't know how then here:
else
{
MessageBox.Show("No internet connection!");
}
Now we want to read the txt file and check if the CPU key the user enters in the textbox exists. So we simply use our string "strings" to see if the cpuKey entered in textbox is contained in the txt file and if it is, we say CPU Authed! or something.
if (strings.Contains(cpuKey = textBox1.Text))
{
MessageBox.Show("CPU Authed", "", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
And yet again we need to notify the user if the CPU Key isn't there. So we simply do:
else
{
MessageBox.Show("Not authed", "", MessageBoxButtons.OK, MessageBoxIcon.Information);
this.Dispose();
}
This is great but not secure and can easily be cracked. That's why I used another method checking a database (But my app is confused so it should be safe).

It's so simple and fun for kids to use. I guess they will say they created it for their tool without credits. But I don't care. It's so simple to do.

A tool that basically checks internet connection, downloads the txt from your website and then reads that file and checks if the CPU you entered in the textBox matches anything inside that text. If it does, it shows a message box saying "Your authed" and if not then it will say "Not authed".

Really. Why did you release it?
We should have kept it. But hey, it's great that the community loves it and I am sure it will help tons.

Use a method which will not download anything to the app and instead connect and disconnect from a database and also confuse your program.
