BinaryCompresser

Overview

BinaryCompresser is a C++ project that provides file compression and decompression functionality. It uses the zlib library for compression and decompression, and offers optional encryption based on the Vernam cipher.

Features

• File Compression: The file_to_binary_string function compresses files into a binary format using zlib. It takes a path to the input file and a path to the output compressed binary file as input. It also takes an optional encryption key.

• File Decompression: The binary_string_to_file function decompresses files from a binary format using zlib. It takes the binary path and the output path as input, as well as an optional decryption key.

• Optional Encryption: The optional encryption is based on the Vernam cipher. If a key is provided, the file_to_binary_string function will encrypt the file before compression, and the binary_string_to_file function will decrypt the file after decompression.

Usage

You can use BinaryCompresser from the terminal as follows:

To compress a file into a binary:

./BinaryCompresser --file-to-binary <input_file_path> <output_binary_path> [key]

To retrive a file from a binary:

./BinaryCompresser --binary-to-file <input_binary_path> <output_file_path> [key]

Performance

I’ve done some performance testing on files up to 200 MBs. Here are the results:

These plots show the time taken to compress files and the size of the compressed files. As you can see, BinaryCompresser is capable of efficiently compressing large files.

Building

This project uses CMake for building. You can build the project as follows:

mkdir build
cd build
cmake ..
make

This will create a build directory, change into that directory, generate the Makefile with CMake, and then build the project with Make.
