How to Use Cryptmount for Encrypted Filesystems on Linux

Looking for a way to create encrypted filesystems on Linux? Cryptmount is a powerful utility that allows any user to access encrypted filesystems on-demand under GNU/Linux systems without requiring root privileges.

It requires Linux 2.6 or higher. It handles both encrypted partitions as well as encrypted files.

It makes it as easy (compared to older approaches such as cryptoloop device driver and dm-cryptdevice-mapper target) for ordinary users to access encrypted filesystems on-demand using the newer devmapper mechanism. Cryptmount helps a system administrator in creating and managing encrypted filesystems based on the kernel’s dm-crypt device-mapper target.
