This cookbook contains an LWRP to manage one-time-use encrypted filesystem using the cryptsetup package in Debian and Ubuntu. On each boot, a filesystem-in-a-file will be created, mounted as a loop device, encrypted via cryptsetup with a randomly-generated key that isn't stored anywhere, and mounted for use. It isn't necessary to reboot for the filesystem resources to become available, but they will be created anew each time a machine reboots.
The intended purpose of this cookbook is for deploying servers which will handle sensitive information on untrusted systems or cloud deployments, so that the filesystems themselves will not be readable outside the running instance. Information stored in the encrypted filesystem will be irretrievable after reboot.
Tested on: * Debian 6.0 * Ubuntu 12.04
This cookbook will only work on Debian or Ubuntu systems if the
package is available. The
cryptsetup package will be installed if it's not

The default recipe won't do anything.
This represents an example of creating a few small encrypted filesystems. You really should be using this only as an LWRP.

Put the following in your cookbook's metadata.rb file to include this LWRP:
The following added to your recipes will create an encrypted filesystem:
encryptfs "data" do size 100 filepath "/cryptfs" mountpath "/usr/local/cryptdata" fstype "ext4" action :create end
The following added to your recipe will delete an encrypted filesystem:
encryptfs "data" do action :delete end
