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.
