.SH DESCRIPTION
.I Cryptsetup
prepares a AES-encrypted partition to be used with the
.IR fs (3)
device.
.PP
The
.B -f
flag formats the partitions
.I files,
generating a new encryption key. The encryption key is
protected by a password that
.I cryptsetup
will prompt for confirmation.
.PP
The flags
.B -i
and
.B -o
activate a previously formated encrypted partition. The
.B -o
flag outputs the
.IR fs (3)
ctl activation commands to standard output where
.B -i
directly writes them to the
.B '/dev/fs/ctl'
file.
.PP
Once activated, the new partition appears under
.BI /dev/fs/ name
where
.I name
is the last path element of the
.I files
argument.
