CryptoFrog is a robust, secure, and user-friendly encryption application developed for Linux Ubuntu. Built with modern C++20 standards, CryptoFrog utilizes a custom elliptic curve (ECCFrog512CK2) alongside powerful cryptographic algorithms such as AES-GCM-256 and Argon2ID for secure, reliable, and efficient file encryption and decryption. Its graphical interface is powered by GTK3, offering a sleek, retro-inspired hacker aesthetic.
CryptoFrog extends the concept from its predecessor project, OpenFrogget, introducing enhanced security, an improved user interface, and more efficient encryption methods.
- Hybrid Encryption: Combines custom elliptic curve cryptography (ECCFrog512CK2) with AES-GCM-256 symmetric encryption.
- Secure Key Derivation: Utilizes Argon2ID, winner of the Password Hashing Competition, for secure key generation.
- User-Friendly GUI: Sleek, intuitive GTK3 interface.
- Efficient: Optimized binary using UPX compression.
- Retro Hacker Aesthetic: Unique user interface inspired by classic hacking tools.
CryptoFrog requires several libraries and tools. Ensure you have the following installed:
- C++20 Compiler (g++)
- GTK3 Development Libraries
- libsodium (Cryptographic library)
- GMP (GNU Multi-Precision Arithmetic Library)
- UPX (Ultimate Packer for eXecutables)
Install dependencies using the provided script:
sudo apt update
sudo apt install -y g++ libgtk-3-dev libsodium-dev libgmp-dev upxClone this repository and navigate into the directory:
git clone https://github.com/yourusername/cryptofrog.git
cd cryptofrogCompile the project using Make:
makeUpon successful compilation, the binary will be located in the build/ directory.
Run CryptoFrog using the following command:
./build/cryptofrog- Open CryptoFrog.
- Select the file you wish to encrypt using the "Choose File" button.
- Enter a strong password in the provided input field.
- Click "Encrypt". CryptoFrog will output an encrypted file with the
.eccextension in the same directory.
- Select an encrypted file (with
.eccextension). - Enter the password used for encryption.
- Click "Decrypt". CryptoFrog will decrypt the file, restoring the original contents.
CryptoFrog uses a hybrid encryption method:
- ECCFrog512CK2: Custom elliptic curve cryptography for secure key exchange.
- AES-GCM-256: Advanced Encryption Standard in Galois/Counter Mode for symmetric encryption.
- Argon2ID: Secure key derivation from user passwords.
ECCFrog512CK2 is a custom-developed elliptic curve designed for high security, rigorously tested to resist known vulnerabilities. This curve represents a substantial upgrade from its predecessor implemented in OpenFrogget.
The final binary is compressed using UPX, reducing the file size significantly without compromising execution speed or security.
