NAME

cryptsetup – setup encrypted partition

SYNOPSIS

disk/cryptsetup -f files ...
disk/cryptsetup -o files ...
disk/cryptsetup -i files ...

DESCRIPTION

Cryptsetup prepares an AES-encrypted partition to be used with the fs(3) device.

The -f flag formats the partition files, generating a new encryption key. The user will be prompted for a password that will be used to protect the encryption key.

The flags -i and -o activate a previously formatted encrypted partition. The -o flag outputs the fs(3) ctl activation commands to standard output, whereas -i directly writes them to the ’/dev/fs/ctl’ file. The user will be prompted for the password that was used to protect the encryption key.

Once activated, the new partition appears under /dev/fs/name where name is the last path element of the files argument.
