cryptmount - a utility for accessing encrypted filesystems
cryptmount is a utility for GNU/Linux operating systems which allows an ordinary user to mount an encrypted filing system without requiring superuser privileges. It is aimed at recent Linux systems using the 2.6 kernel series.
cryptmount allows management and user-mode mounting of encrypted filing systems on GNU/Linux systems. Filesystems & crypto-swap can be on either raw block devices or ordinary files, with device-mapper (dm-crypt) and loopback devices setup automatically.
