SEALCrypt 🔐

SEALCrypt is a C++ library that provides homomorphic encryption capabilities using Microsoft SEAL. It offers a simplified interface for common encryption operations while leveraging the power of SEAL's homomorphic encryption features.

🌟 Features

• File encryption/decryption using homomorphic encryption
• Streamlined SEAL integration
• Thread-safe file handling
• Comprehensive test suite
• CMake-based build system
• Can be used as both a standalone executable and a library

📋 Prerequisites

• CMake (>= 3.12)
• C++17 compatible compiler
• Microsoft SEAL (>= 4.1)
• Git (for installation)

🚀 Installation

Building from Source

git clone https://github.com/arianizadi/SEALCrypt.git
cd SEALCrypt
mkdir build && cd build
cmake ..
make
sudo make install

Uninstalling

# From the build directory
sudo make uninstall

💻 Usage

As a Library

1. CMake Integration

find_package(sealcrypt REQUIRED)
target_link_libraries(your_target PRIVATE sealcrypt::sealcrypt)

2. Basic Example

#include <sealcrypt/encrypt.hpp>
#include <sealcrypt/decrypt.hpp>
#include <sealcrypt/file_handler.hpp>

int main() {
    // Your encryption/decryption code here
    return 0;
}

As an Executable

# Encrypt a file
sealcrypt encrypt --input input.txt --output output.encrypted --public-key public.key

# Decrypt a file
sealcrypt decrypt --input output.encrypted --output decrypted.txt --private-key private.key

🧪 Testing

SEALCrypt comes with a comprehensive test suite. Each component has its own test file that can be run independently.

# Build and run all tests
cd build
make
make run_all_tests

# Run specific test
./tests/test_encryptor
./tests/test_decryptor
./tests/test_file_handler

📚 Example CMakeLists.txt

cmake_minimum_required(VERSION 3.10)

# Set the project name
project(TestProject)

# Specify the C++ standard
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED True)

# Find the SEALCrypt library
find_package(SEALCrypt REQUIRED)

# Add the executable
add_executable(main main.cpp)

# Link the SEALCrypt library
target_link_libraries(main PRIVATE sealcrypt::sealcrypt)

Key Components

• Encryptor: Handles encryption operations using SEAL's homomorphic encryption
• Decryptor: Manages decryption of homomorphically encrypted data
• FileHandler: Provides thread-safe file operations for encrypted data
