Fedora 7 provides basic support for encrypted swap partitions and non-root file systems. To use it, add entries to /etc/crypttab and reference the created devices in /etc/fstab.

	Encrypted FS Support Unavailable During Install
	Enable file system encryption after installation. Anaconda does not have support for creating encrypted block devices.

The following example shows an /etc/crypttab entry for a swap partition:

my_swap /dev/sdb1 /dev/urandom swap,cipher=aes-cbc-essiv:sha256 

This creates an encrypted block device /dev/mapper/my_swap, which can be referenced in /etc/fstab. The next example shows an entry for a filesystem volume:

my_volume /dev/sda5 /etc/volume_key cipher=aes-cbc-essiv:sha256 

The /etc/volume_key file contains a plaintext encryption key. You can also specify none as the key file name, and the system instead asks for the encryption key during boot.

The recommended method is to use LUKS for file system volumes: (using LUKS you can drop the cipher= part in crypttab).
