G-encryptor

Overview

This project coded in python allows the user to encrypt/decrypt files in a specified directory.

Modes

There are two modes, the user-friendly and the machine-friendly.

User-friendly

Displays the menu, logo and options for user to select. Outputs every change it makes, including deletions, encryptions and decryptions

./g-encryptor.sh

and this will display the menu with its options

Machine-friendly

This is a mode which a script can call the file, pass an argument (encrypt/decrypt) and the script will do the thing

./g-encryptor.sh encrypt
./g-encryptor.sh decrypt

that will encrypt/decrypt the specified directory (TARGET_DIR)

Usage

If you are in user mode, run just ./g-encryptor.sh. If it is running on machine mode, run ./g-encryptor <encrypt|decrypt>. Make sure that the configuration file (config.ini) has the target_dir variable set and does not finish with a final /. This is important as the script won't be able to handle paths with an ending slash. I've added filters to strip the slash when the target_dir changes.

Options

1. Install packages: This allows to install the requried packages for the script to run properly. You should run it at least once. In the bin branch the files have been compiled to binary to prevent this.
2. Encrypt: This encrypts all files in the target_dir directory recursively except the ones with the GNOENCRYPT flag (see GNOENCRYPT flag below).
3. Decrypt: This decrypts all files in the target_dir directory recursively except the ones with the GNOENCRYPT flag.
4. Change config directory path: This allows to change the target_dir variable by directly writing to $CONFIG_FILE (defined in line 5 of g-encryptor.sh), normally config/config.ini.
5. Exit: Exits the script.

GNOENCRYPT flag

The text "GNOENCRYPT" has been introduced in all files required by this program. This prevents encrypt.py or decrypt.py to touch or corrupt the files.

Other requirements

File server.php must be avaliable in $seed_url (defined in encrypt.py line 13) for the decryption of the files. The current url is localhost:80/banana/index.php and the hash_pass with the now flag ending must be passed through for the proper decryption. Else, decrypt.py will crash.

I'll finish README.md soon
