LOL File Wrapper is a desktop application for packing and encrypting files, built in Python with a PySide6 graphical interface. It lets you take one or several files, bundle them into a single archive, and protect that archive with encryption so its contents stay private. By default, the resulting archive uses a custom .lol file extension, though the tool lets you choose a different extension if you prefer. Before packing, files are compressed with zlib to reduce their size, though the README notes the compression is not especially strong. Unpacking restores the original files exactly, with no data lost in the process. On the security side, the tool uses AES-256 encryption in CTR mode, with passphrases turned into encryption keys through PBKDF2HMAC using SHA-256 and 200,000 iterations, a method designed to slow down anyone trying to guess the password. Each encrypted archive gets its own random salt and nonce, and the original filenames inside the archive are scrambled with a custom cipher so they are not stored in plain text in the file's metadata. The README includes a clear warning: there is no password recovery option built in. If you encrypt a file and forget the passphrase, the data cannot be recovered. To run it from source, you need Python 3.9 or newer along with two extra packages, PySide6 and cryptography, both installable with pip. A ready-to-run Windows executable and installer are also provided for people who do not want to run the Python script directly. The project does not state what mac or Linux users should do beyond running the script themselves.
