Installing IconCaptcha on Void Linux

IconCaptcha is a free, open source service that uses unique icons instead of letters and numbers to make it easier for users to verify their identity on websites. In this tutorial, we'll walk through the steps to install IconCaptcha on Void Linux.

Prerequisites

Before you get started, you'll need to make sure that you have the following prerequisites installed on your Void Linux system:

  • Git
  • NPM
  • Node.js

Steps

Once you've confirmed that you have the prerequisites installed, follow these steps to install IconCaptcha on Void Linux:

Step 1: Clone the IconCaptcha repository

Open a terminal window and navigate to the directory where you want to install the IconCaptcha. Then, clone the IconCaptcha repository by running the following command: 

git clone https://github.com/FabianWe/IconCaptcha.git

This will clone the entire repository into a local directory called IconCaptcha.

Step 2: Install and configure dependencies

To install the dependencies required by IconCaptcha, navigate to the IconCaptcha directory you just cloned and run the following command: 

npm install

This will install all required dependencies listed in package.json.

Step 3: Configuration

In order to use IconCaptcha effectively, you will need to configure some parameters by modifying the config.json file.

Here's an example configuration file: 

{
    "useReverseProxy": false,
    "port": 8080,
    "iconSet": "bootstrap",
    "numOfIcons": 25,
    "minSelected": 4,
    "maxSelected": 4,
    "minRotation": 20,
    "maxRotation": 40,
    "icon": {
        "width": 60,
        "height": 60
    },
    "canvas": {
        "width": 400,
        "height": 200
    }
}

You can modify the parameters according to your website requirements. Here are some of the parameters you can config:

  • number-of-icons: Total number of icons that you want to display on the captcha
  • min-selected: Minimum number of icons that the user must select in order to complete the captcha
  • max-selected: Maximum number of icons that the user can select in order to complete the captcha
  • min-rotation: Minimum rotation value for the icons displayed
  • max-rotation: Maximum rotation value for the icons displayed

Once you have modified the parameters according to your requirements, save the configuration file.

Step 4: Start the server

To start the IconCaptcha server, run the following command in your terminal window while inside the IconCaptcha directory: 

npm start

This will start the server and make it available at http://localhost:8080 by default. You can now integrate the IconCaptcha into your website.
