A Java library for license key validation. The license key is retrieved from a Raw Pastebin URL and compared against the license key provided by the user.

The library is provided as a JAR file. You can include it in your project and use the LicenseChecker class to check the license key.

Constructor:

public LicenseChecker(String pastebinRawUrl, String licenseKey)

Creates a new LicenseChecker that searches for the license key in the specified Raw Pastebin URL and compares it with the licenseKey provided by the user.

• pastebinRawUrl - The Raw Pastebin URL that contains the license key.
• licenseKey - The license key provided by the user.

Method:

public boolean checkLicenseKey() throws IOException

Checks whether the license key provided by the user is contained in the content of the specified Raw Pastebin URL.

Here's an example that shows how you can use the library in your Java code:

import java.io.IOException;

public class MyProgram {
    public static void main(String[] args) {
        LicenseChecker checker = new LicenseChecker("https://pastebin.com/raw/PASTE_ID", "LICENSE_KEY");
        try {
            if (checker.checkLicenseKey()) {
                System.out.println("License key is valid.");
            } else {
                System.out.println("Invalid license key.");
            }
        } catch (IOException e) {
            System.out.println("Error checking license key: " + e.getMessage());
        }
    }
}

In this example, a LicenseChecker is instantiated with the Raw Pastebin URL and license key, and the checkLicenseKey method is called. If the license key is valid, a message is printed saying that the license key is valid. Otherwise, a message is printed saying that the license key is invalid.
