DM CryptFS provides helper tools for setting up swap partitions and filesystems using the device mapper crypt target of the Linux kernel 2.6.4 and later. A configuration file lets you specify the layout of the encrypted storage and key derivation. Some scripts are provided to make it interact nicely with hotplugging.
