Sets up a dmcrypt mapping

Parameters:

• target – device mapper logical device name
• device – underlying block device
• cipher – encryption cipher string digestible by cryptsetup
• key_size – encryption key size
• key – encryption key as an array of unsigned bytes

delete_volume(target)

Deletes a dmcrypt mapping

Parameters:target – name of the mapped logical device

is_encrypted(path)

Returns true if the path corresponds to an encrypted disk.
