WP_Recovery_Mode_Cookie_Service::recovery_mode_hash() │ private │ WP 5.2.0

Gets a form of wp_hash() to Recovery Mode.

We cannot use wp_hash() 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.

Method of the class: WP_Recovery_Mode_Cookie_Service{}

No Hooks.

Return

String|false. The hashed $data, or false on failure.

Usage

// private - for code of main (parent) class only
$result = $this->recovery_mode_hash( $data );

$data(string) (required)

Data to hash.
