Passport keys
In Chapter 9, Adding a User Login and API Authentication with Passport, we
created encryption keys for Passport with the php artisan passport:install
command. These keys are stored in text files that can be found in the storage
directory.
Encryption keys should not be under version control, as this would make them
insecure. Instead, we need to regenerate these keys on each deploy. We can do
this by adding a post-install script to our composer file.
composer.json: "scripts": {
...
"post-install-cmd": [ "Illuminate\\Foundation\\ComposerScripts::postInstall",
"php artisan optimize",
"php artisan passport:install"
],
}
