WP_Recovery_Mode_Cookie_Service::recovery_mode_hash( string $data )

Gets a form of wp_hash() specific to Recovery Mode.


Description

We cannot use wp_hash() because it is defined in pluggable.php which is not loaded until after plugins are loaded, which is too late to verify the recovery mode cookie.

This tries to use the AUTH salts first, but if they aren’t valid specific salts will be generated and stored.
