# Directions for creating the encrypted key that will be used to initialize

|
# Create the EVM key (encrypted key type)
|
||
|
|
#
|
||
|
|
# The encrypted key is a random number encrypted/decrypted using the
|
||
|
|
# kernel master key. The encrypted key is only exposed to userspace
|
||
|
|
# as an encrypted datablob.
|
||
|
|
$ keyctl add encrypted evm-key "new trusted:kmk-trusted 32" @u

# Save the encrypted key

$ su -c 'keyctl pipe `keyctl search @u encrypted evm_key` > /etc/keys/evm-trusted.blob'

# The EVM 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:
|
||
|
|
--------------------------------------------------------------------------
|
||
|
|
EVMKEY="/etc/keys/evm-trusted.blob"
|
||
|
|
--------------------------------------------------------------------------
|
||
|
|
|
||
|
|
2) create the configuration file '/etc/sysconfig/evm' and set the EVMKEY variable;
|
||
|
|
|
||
|
|
3) specify the EVM key path name in the 'evmkey=' parameter of the kernel command
|
||
|
|
line.
