How can I change the default wordpress password hashing system to something custom?

1. Just figured it out. So thought to leave the solution here, if someone else need it:

   To change the default hashing system, need to overwrite wp_hash_password() function: (can be done in a plugin)

   if ( !function_exists('wp_hash_password') ){
       function wp_hash_password($password) {
                   //apply your own hashing structure here
               return $password;
       }
   }
   

   Now you will need to overwrite wp_check_password() to match your hashing structure: (can be done in a plugin as well)

   if ( !function_exists('wp_check_password') ){
       function wp_check_password($password, $hash, $user_id = '') {
               //check for your hash match
               return apply_filters('check_password', $check, $password, $hash, $user_id);
               }
   }
   

   Please check wp_check_password
