Sure, here is a tutorial for installing SimpleX Chat on Kali Linux:

Installing SimpleX Chat on Kali Linux

Step 1: Install Dependencies

Before installing SimpleX Chat, we need to install its dependencies:

sudo apt-get install nodejs npm git libssl-dev libffi-dev python-dev build-essential

Step 2: Clone the Repository

Next, we need to clone the SimpleX Chat repository:

git clone https://github.com/simplex-chat/simplex-chat.git

Step 3: Install Node.js Modules

Navigate to the cloned repository and install the required Node.js modules:

cd simplex-chat
npm install

Step 4: Configure the Database

SimpleX Chat uses PostgreSQL as its database. To set up the database, we need to create a new user and database:

1. Log in to PostgreSQL as the root user:

   sudo -u postgres psql
   

2. Create a new user and database:

   CREATE USER simplexchat WITH PASSWORD 'password';
   CREATE DATABASE simplexchat;
   GRANT ALL PRIVILEGES ON DATABASE simplexchat TO simplexchat;
   

3. Exit the PostgreSQL command line:

   \q
   

Step 5: Configure the Environment Variables

Create a new .env file in the simplex-chat directory:

touch .env

Open the file in a text editor and add the following lines:

PORT=3000
NODE_ENV=development
SECRET_KEY=<random_string_of_characters>
DATABASE_URL=postgres://simplexchat:password@localhost/simplexchat

Replace <random_string_of_characters> with a strong secret key of your choice.

Step 6: Start SimpleX Chat

You can now start SimpleX Chat by running:

npm start

The application will be available at http://localhost:3000.
