How to solve and bypass text captcha (letter captcha): Code examples

To bypass text CAPTCHAs (letter CAPTCHAs) and automate user input processes in accessibility tasks, a variety of sophisticated techniques can be employed.

This article explores how recognition technologies are utilized to solve and bypass text CAPTCHAs, ensuring a balance between automation precision and efficiency.

Text (letter) captcha bypass reasons

he goal of using recognition technologies is not to undermine security but to enhance and streamline testing and automation processes while addressing accessibility challenges. CAPTCHAs, particularly letter-based ones, often create significant barriers for individuals with disabilities, necessitating the development of more inclusive and user-friendly alternatives.

For automation tasks, such as web scraping, text CAPTCHAs introduce additional complexity by targeting and blocking bots through increasingly sophisticated methods. Bypassing these CAPTCHAs often requires leveraging advanced machine learning models or external APIs, which can make automation processes more resource-intensive. Striking a balance between security, efficiency, and accessibility is essential to ensure equitable and effective solutions for all users.

PHP

To integrate 2Captcha's Text Captcha solving service into your PHP project, follow these steps:

  1. Install the PHP Package:

Using Composer:

     composer require 2captcha/2captcha

Manual Installation:

       require 'path/to/src/autoloader.php';
  1. Configure the Client:
require 'vendor/autoload.php'; // Adjust the path if necessary

use TwoCaptcha\TwoCaptcha;

$solver = new TwoCaptcha('YOUR_API_KEY');

Replace YOUR_API_KEY with your actual 2Captcha API key.

  1. Bypass a Text Captcha:
try {
    $result = $solver->text([
        'text' => 'If tomorrow is Saturday, what day is today?',
     'lang' => 'en', // Optional: specify language if needed
    ]);
    echo 'Captcha solved: ' . $result->code;
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}

In this example, the question If tomorrow is Saturday, what day is today? is sent to 2Captcha for solving. The response, containing the answer, is then displayed.

Note: Ensure proper error handling in your implementation to manage potential exceptions that may arise during the captcha-solving process.

For more detailed information and additional configuration options, refer to the PHP captcha solver.

Java

To bypass Text Captcha using solving service into your Java project, follow these steps:

  1. Install the Java Package:

Add the 2Captcha Java library to your project by including the following dependency in your pom.xml file:

   <dependency>
       <groupId>com.github.2captcha</groupId>
       <artifactId>2captcha-java</artifactId>
       <version>1.3.0</version>
   </dependency>

This dependency allows for seamless integration with the API.

  1. Configure the Client:
   import com.twocaptcha.TwoCaptcha;

   TwoCaptcha solver = new TwoCaptcha("YOUR_API_KEY");

Replace YOUR_API_KEY with your actual 2Captcha API key. This sets up the client to interact with the 2Captcha service.

  1. Bypass a Text Captcha:
   import com.twocaptcha.captcha.Text;

   public class TextCaptchaExample {
       public static void main(String[] args) {
           TwoCaptcha solver = new TwoCaptcha("YOUR_API_KEY");

           Text captcha = new Text();
           captcha.setText("If tomorrow is Saturday, what day is today?");
           captcha.setLang("en"); // Optional: specify language if needed

           try {
               solver.solve(captcha);
               System.out.println("Captcha solved: " + captcha.getCode());
           } catch (Exception e) {
               System.out.println("Error: " + e.getMessage());
           }
       }
   }

In this example, the question If tomorrow is Saturday, what day is today? is sent to the service for solving. The response, containing the answer, is then displayed.

Note: Ensure proper error handling in your implementation to manage potential exceptions that may arise during the captcha-solving process.

For more detailed information and additional configuration options, refer to the Java captcha solver.

C#

  1. Bypass a Text Captcha:
   using System;
   using System.Linq;
   using TwoCaptcha.Captcha;

   public class TextCaptchaExample
   {
       public static void Main()
       {
           var solver = new TwoCaptcha("YOUR_API_KEY");

           var captcha = new Text();
           captcha.SetText("If tomorrow is Saturday, what day is today?");
           captcha.SetLang("en"); // Optional: specify language if needed

           try
           {
               solver.Solve(captcha).Wait();
               Console.WriteLine("Captcha solved: " + captcha.Code);
           }
           catch (AggregateException e)
           {
               Console.WriteLine("Error: " + e.InnerExceptions.First().Message);
           }
       }
}

In this example, the question If tomorrow is Saturday, what day is today? is sent to the service for solving. The response, containing the answer, is then displayed.
