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

# 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
782117972

# 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.


# Directions for loading a custom IMA policy.

# Write the policy following the instructions provided in the file
# 'Documentation/ABI/testing/ima_policy' of the kernel documentation.

# Save the policy in a file.

# Create the configuration file '/etc/sysconfig/ima' to override the path name of
# the IMA custom policy.
------------- '/etc/sysconfig/ima' (with the default value) -------------
IMAPOLICY="/etc/sysconfig/ima-policy"
