FFLocker

Locking files/folders in GNU/Linux via text-based user interface (TUI).

The most important part of the algorithm is that during the locking process, your password is never saved on the computer and only displayed in the terminal for you to save it.

Description

FFLocker uses AES encryption. You can either create a password with 16, 24, and 32 characters (which corresponds to 128, 192, 256 bits, respectively) or generate a random password with the help of the secrets.choice.

After you lock the file/folder, the program will change the binary data of the file/folder, and it will overwrite the files. To read/open the encrypted files, you have to enter the password.

I have programmed the code so that when you decrypt the file/folder, a new file/folder will be created as a precaution against entering the wrong password. After the decryption is complete, you can permanently delete the encrypted file/folder via a single command.

Additionally, I have also programmed the code in such a way that every file and folder receives .enc and ENC extensions respectively. If your pathname does not contain these extensions, the decryption process does not start.

WARNING

Even your password is wrong, the program will decrypt the file/folder and produce a result, if it has a sufficient number of characters (bytes). In this case, be careful about deleting the encrypted file/folder since the decrypted one will be unreadable due to the wrong password. As for advice, always open and read the decrypted file/folder before you delete the encrypted one.

Installation

You can easily install the FFLocker via pip

python3 -m pip install fflocker

or directly clone

git clone https://github.com/seVenVo1d/FFLocker.git

to your desired directory.

Requirements

FFLocker requires pycryptodome which can be installed by running

python3 -m pip install pycryptodome

User Guide

To start the file locking process simply run

python3 -m fflocker.file_locker

Similarly, to start the folder locking process run

python3 -m fflocker.folder_locker

Upcoming Features

I am thinking to implement a command line interface (CLI) and it will probably look like this:

$ fflocker -Fe [path]
$ fflocker -De [path]
$ fflocker -Fd [path]
$ fflocker -Dd [path]

-F --File
-D --Directory
-e --encrypt
-d --decrypt
