# Directions for creating the encrypted key that will be used to mount an
|
||
|
|
# eCryptfs filesystem
|
||
|
|
|
||
|
|
# Create the eCryptfs key (encrypted key type)
|
||
|
|
#
|
||
|
|
# The encrypted key type supports two formats: the 'default' format allows
|
||
|
|
# to generate a random symmetric key of the length specified, the 'ecryptfs'
|
||
|
|
# format generates an authentication token for the eCryptfs filesystem,
|
||
|
|
# which contains a randomly generated key. Two requirements for the latter
|
||
|
|
# format is that the key description must contain exactly 16 hexadecimal
|
||
|
|
# characters and that the encrypted key length must be equal to 64.
|
||
|
|
$ keyctl add encrypted 1000100010001000 "new ecryptfs trusted:kmk-trusted 64" @u
|
||
|
|
782117972
|
||
|
|
|
||
|
|
# Save the encrypted key
|
||
|
|
$ su -c 'keyctl pipe `keyctl search @u encrypted 1000100010001000` > /etc/keys/ecryptfs-trusted.blob'
|
||
|
|
|
||
|
|
# The eCryptfs key path name can be set in one of the following ways (specified in
|
||
|
|
# the order in which the variable is overwritten):
|
||
|
|
|
||
|
|
1) use the default value:
|
||
|
|
--------------------------------------------------------------------------
|
||
|
|
ECRYPTFSKEY="/etc/keys/ecryptfs-trusted.blob"
|
||
|
|
--------------------------------------------------------------------------
|
||
|
|
|
||
|
|
2) create the configuration file '/etc/sysconfig/ecryptfs' and set the ECRYPTFSKEY
|
||
|
|
variable;
|
||
|
|
|
||
|
|
3) specify the eCryptfs key path name in the 'ecryptfskey=' parameter of the kernel command
|
||
|
|
line.
|
||
|
|
|
||
|
|
# The configuration file '/etc/sysconfig/ecryptfs' is also used to specify
|
||
|
|
# more options for mounting the eCryptfs filesystem:
|
||
|
|
|
||
|
|
ECRYPTFSSRCDIR: existent directory in the lower root filesystem;
|
||
|
|
ECRYPTFSDSTDIR: mount point directory for the eCryptfs filesystem (the directory must be
|
||
|
|
created in the root filesystem before rebooting the platform);
|
||
|
|
ECRYPTFS_EXTRA_MOUNT_OPTS: extra mount options for the eCryptfs filesystem (the 'ecryptfs_sig'
|
||
|
|
option is automatically added by the dracut script).
|
||
|
|
|
||
|
|
# Example of the configuration file:
|
||
|
|
----------- '/etc/sysconfig/ecryptfs' (with default values) -----------
|
||
|
|
ECRYPTFS_KEY="/etc/keys/ecryptfs-trusted.blob"
|
||
|
|
ECRYPTFSSRCDIR="/secret"
|
||
|
|
ECRYPTFSDSTDIR="${ECRYPTFSSRCDIR}"
|
||
|
|
ECRYPTFS_EXTRA_MOUNT_OPTS=""
|
||
|
|
-----------------------------------------------------------------------
|
||
|
|
|
||
|
|
# If the variable ECRYPTFSDSTDIR is not specified in the configuration file,
|
||
|
|
# its value will be equal to that of ECRYPTFSSRCDIR.
