我想使用橢圓曲線加密使用Matyas Danter的phpecc庫在1中可用。不過，我收到以下錯誤，當我創建變量翹，雖然傳遞的參數是一個點..請幫助..橢圓曲線加密PHP：可捕捉的致命錯誤參數1傳遞給__construct（）
Catchable fatal error: Argument 1 passed to EcDH::__construct() must be an instance of Point, string given, called in C:\xampp\htdocs\ECC-example.php on line 31 and defined in C:\xampp\htdocs\classes\EcDH.php on line 39
