Awesome

Overview

A wrapper to act as a safe. By default, the safe will look for a ~/safe directory and produce ~/safe.tar.gz.asc

Assumptions

• Your GnuPG config is sane

Usage

./safe.sh -h

Configuration

The following variables are supported. These can be maintained in ~/.saferc or any usual environment file such as ~/.bashrc

If you want to create a safe of /my/stuff, create a ~/.saferc with:

SOURCE_DIR - This directory will be encrypted into a safe. For example, setting this to /my/stuff will result in /my/stuff.tar.gz.asc being created.

When not defined, SOURCE_DIR will default to ~/safe

MY_GPG_KEY - The gpg key ID used for encryption

When not set, the script will fall back to using whoami. This assumes your key can be identified using the id you are logged in with.

SAFE_BACKUP_HOST - A host to scp backups to. It is always best to maintain a a definition of this host in your ~/.ssh/config in order to specify details such as a non-standard port, etc.

SAFE_AUTO_BACKUP - Setting this to 1 will trigger a backup any time the contents of the safe are modified

Examples (using default configuration and my cat's account)

$ pwd
/home/evil
$ ls safe*
ls: cannot access safe*: No such file or directory
$ mkdir safe
$ for i in $(seq 3); do echo "secret number $i" > safe/file$i; done
$ safe.sh -C
$ ls safe*
safe.tar.gz.asc
$ safe.sh -l
safe/
safe/file1
safe/file2
safe/file3
$ safe.sh -o file3
secret number 3
$ safe.sh -r file1
$ safe.sh -l
safe/
safe/file2
safe/file3
$ > /tmp/foobar
$ safe.sh -a /tmp/foobar
$ test -f /tmp/foobar || echo gone
gone
$ safe.sh -l
safe/
safe/file2
safe/file3
safe/foobar
$ > ~/please_do_not_shred_me
$ safe.sh -A ~/please_do_not_shred_me
$ safe.sh -l
safe/
safe/file2
safe/file3
safe/foobar
safe/please_do_not_shred_me
$ test -f ~/please_do_not_shred_me && echo still here
still here
