This script manually creates a secure key within the secret data root folder (configured in
config.php as \$CFG->secretdataroot). You must run it using an account with access to write
to that folder.

In normal use Moodle automatically creates the key; this script is intended when setting up
a new Moodle system, for cases where the secure folder is not on shared storage and the key
may be manually installed on multiple servers.

Options:
-h, --help         Print out this help
--method <method>  Generate key for specified encryption method instead of default (sodium)

Example:
php admin/cli/generate_key.php
