🔐 DPF: Data Protection Framework

DPF is a lightweight, cross-platform Data Protection Framework for securely encrypting and storing sensitive information in custom .dpf files using AES-256 encryption.

✨ Features

• 🔑 AES-256 Encryption (CBC Mode) for robust data security.
• 🛠️ Automatic PKCS7 Padding ensures data integrity.
• 🔏 Metadata storage (author, creation timestamp, description).
• 📂 Custom .dpf format for structured encrypted storage.
• 📖 Easy-to-use API for seamless encryption and decryption.
• 🖥️ Cross-platform support (Python and Java).
• 📜 Graphical User Interface (GUI) for reading .dpf files.

🚀 Usage

🔹 Python Implementation

cd python

1️⃣ Encrypt and Store Data

from dpf import DPF

dpf = DPF()
data_list = ["Secret1", "ConfidentialData2"]
dpf.create("my_secure_file", data_list, "Sample Encrypted File", "John Doe", "MySecretKey123", "MySaltValue")

2️⃣ Read and Decrypt Data

from dpf import DPF

dpf = DPF()
decrypted_data = dpf.read("my_secure_file.dpf", "MySecretKey123", "MySaltValue")
print(decrypted_data)  # Original data restored

🔹 GUI Mode (Read Only)

python gui.py

---

🔹 Java Implementation

cd java

Example Code:

import java.util.Arrays;
import java.util.List;

public class Test {
    public static void main(String[] args) {
        List<String> dataList = Arrays.asList(
            "Hello, World!",
            "This is a test.",
            "Sample encrypted data."
        );

        // Metadata
        String description = "Sample file with encrypted data";
        String author = "John Doe";

        // Encryption key and salt (must match for decryption)
        String key = "mysecretkey";
        String salt = "randomsalt123";

        // Create DPF instance
        DPF dpf = new DPF();

        // Create and save the .dpf file
        String filename = "testfile";
        dpf.create(filename, dataList, description, author, key, salt);

        // Read and decrypt the file
        List<String> decryptedDataList = dpf.read(filename, key, salt);

        // Print decrypted data
        System.out.println("Decrypted Data:");
        for (String decryptedData : decryptedDataList) {
            System.out.println(decryptedData);
        }
    }
}
