Encrypted Directory

Using ecryptfs-utils this Bash script makes a setup for an encrypted environment inside of the created ecryptfs directory. It works out-of-the-box under Arch Linux based systems. Also it supports sound feedback using sox and autmatic unmounting using timeout settings and more.

Getting Started

Execute ./src/main.sh. It's using Pacman to install requirements if needed. After the script was executed, inside of the encrypted environment you can create your own .bashrc and if your exiting the shell using exit the encrypted directory will be automaticly unmounted (default) and environment variables like $HOME will be set to default.

Dependencies

The required packages for the complete support of every feature (some are optional like sound feedback) can be found within the ./src/setup.sh.

• sox
• ecryptfs
• firefox

Setting Up

As explained normally the script installs the dependencies automaticly and finds the location of the encrypted directory by itself.

#!/bin/bash
git clone git@github.com:TheUnixDemon/EncryptedDirectory.git && ./EncryptedDirectory/src/main.sh 

For using this script later on look into Start Script. Also if you want to use the arguments inside of the encrypted environment that you will enter after starting the script, make use of the explaination of Private Directory to load this script inside of the same shell level . Furthermore to check or alter the settings of this script go to Settings.

Arguments

The script ./src/main.sh supports some arguments like ...

• -u - unmount encrypted directory
• -p - copying from encrypted directory to ./preset
• -f - starting a Firefox instance inside of encrypted environment

#!/bin/bash
./src/main.sh -f # starting firefox

Start Script » Shell Level One to Two

You start the script in a sub shell when you are in Shell level 1. So it will load up it's variables outside of your first shell.

#!/bin/bash
./src/main.sh"

Private Directory » Shell Level Three

If you are within the private environment you are within the shell level 3. So you should load scripts using source. ($WORKINGDIR - script location)

#!/bin/bash
SCRIPT=$(cd "$WORKINGDIR" && source "main.sh")

Settings

As explained at the beginning, you can alter the default settings at ./src/env.sh.

#!/bin/bash 
...
# options
SOUND="false"       # enable/disable sox notification feedback for unmounting
TIMEOUT="false"     # automaticly umount after TLIMIT if no inteference
TLIMIT=60           # time limit
USE_FIREFOX="false" # automaticly starting firefox after mounting the encrypted directory

If TIMEOUT="true" and TLIMIT=60 every sixty secounds the script will check if a process is using the encrypted directory. If not the mounted directory will be unmounted afterwards. Also If you have set SOUND="true" a sound will accure to notify you that your encrypted directory was successfully unmounted.
