I decided to do this project to learn more about bigger c++ project and how to develop, maintain and create unit tests and pipelines.

This is a Qt application that uses the Crypto++ library, allowing users to select a directory and perform various cryptographic operations. The application utilizes QMainWindow for the main window and QVBoxLayout for the layout. CryptIT utilizes GitHub Actions to automatically run unit tests on pull requests to the main branch, ensuring code integrity and reliability throughout development. This streamlined process enhances collaboration and maintains high standards of software quality and security, so feel free to contribute as much as you want and can!

To use the program, you will need to open the executable and select a directory that you either want to encrypt or decrypt. Once a directory is selected, you can choose the number of threads the program should use; the more threads selected, the faster the process. Afterward, you can press the "Load files" button to view an overview of the number of files and a small sample of the selected files that will either be decrypted or encrypted. The program includes checks to ensure you cannot encrypt already encrypted files and verifies the correctness of the password before decrypting the files. Once a password is entered, only one button, either "encrypt" or "decrypt," will be available depending on whether the files are already encrypted or decrypted.
