# Automount LUKS Filesystems

## Overview

This script automates the process of mounting and unmounting LUKS-encrypted filesystems. It uses a configuration file to store the device UUIDs, mount points, and encrypted passphrases.

## Requirements

* Python 3.x
* `argparse` library
* `cryptography` library
* `subprocess` library

## Configuration File

The configuration file is expected to be in the following format:

```
uuid  mount_point  encrypted_passphrase
```

For example:

```
f48bfd48-e478-4fd1-97b0-5bf66844b584  /media/yazoo/luks-f48bfd48-e478-4fd1-97b0-5bf66844b584  c6jvKUgjvNhImxO2OpndSHRMeO4N7+R2oN2i2eiqsXwSqMCD2juqSXRSUI8QrNOqR/SLRX5vkBZkwZ669Xv8nRXHpeWsSzr7t9qUjz48tIgTH/sfVDkxztyKre247M4hRAHUBevXTFRaa8H81w3x59Loix5/nlZ0EqYgyM/vSZzGv3hZIeIia2tWxE8b7Mbb/BwCj9fjxVgTD5v0TsfHQftf/BwWJcFqIleFDaD84hVfzAyOwNJhn56DanbUiwHnKwgr/HZ7/36UZ/rbB7zBaLt2hFaY3t6012bdkEzOe9/9b0UCXtoMeL9XmNQm5mWEtzOlcoUJUlpNkZSuaaJV+g==
```

## Usage

The script can be run with the following options:

```
$ python automount_luks.py -h
usage: automount_luks.py [-h] [-m] [-c CLOSE] [-f CONFIG_FILE]

optional arguments:
  -h, --help            show this help message and exit
  -m, --mount           Mount the specified device
  -c CLOSE, --close CLOSE
                        Close the specified device
  -f CONFIG_FILE, --config CONFIG_FILE
                        Specify a configuration file
```

## Key Generation

The script uses RSA keys to encrypt and decrypt the passphrases. The keys can be generated using the `crypt_tools.py` script:

```
$ python crypt_tools.py
```

This will generate a private key file (`private_key.pem`) and a public key file (`public_key.pem`).

## Notes

* The script assumes that the `cryptsetup` and `mount` commands are installed and available on the system.
* The script uses the `sudo` command to run the `umount` and `cryptsetup` commands with elevated privileges.
* The script does not handle errors well, and may require additional error handling and logging in a production environment.
