|
|
prepares an AES-encrypted partition to be used with the
|
2012-07-05 17:17:03 +00:00
|
|
|
.IR fs (3)
|
|
|
|
|
device.

The
|
|
|
|
|
.B -f
|
2012-07-05 17:34:26 +00:00
|
|
|
flag formats the partition
|
2012-07-05 17:17:03 +00:00
|
|
|
.I files,
|
2012-07-05 17:34:26 +00:00
|
|
|
generating a new encryption key. The user will be prompted
|
|
|
|
|
for a password that will be used to protect the encryption key.

|
|
|
|
|
and
|
|
|
|
|
.B -o
|
|
|
|
|
activate a previously formated encrypted partition. The
|
|
|
|
|
.B -o
|
|
|
|
|
flag outputs the
|
|
|
|
|
.IR fs (3)
|
2012-07-07 21:13:49 +00:00
|
|
|
ctl activation commands to standard output, whereas
|
2012-07-05 17:17:03 +00:00
|
|
|
.B -i
|
|
|
|
|
directly writes them to the
|
|
|
|
|
.B '/dev/fs/ctl'
|
2012-07-07 21:13:49 +00:00
|

file. The user will be prompted for the password that was used
|
|
|
|
|
to protect the encryption key.

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