Fort Knox is a virtual encrypted file system. You can place some files in the ‘files’ directory and run fortKnox.py, login and encrypt those files. These files will be encrypted and stored in the ‘vault’. Now you can delete those files in the ‘files’ folder. To retrieve them you can decrypt them using Fort Knox. Fort Knox has its own terminal like unix with some basic commands.
The main aim of this software is to store the files securely in a virtual file system and retrieve the required files as needed.
