이러한 암호화 방법 중에서 AES-256-CBC를 가져올 수 있는 방법은 다음과 같습니다.



#hostingforum.kr
php

$cipher_methods = openssl_get_cipher_methods();

foreach ($cipher_methods as $method) {

    if (strpos($method, 'AES-256-CBC') !== false) {

        echo $method . "n";

    }

}



이 코드는 openssl_get_cipher_methods 함수의 결과에서 AES-256-CBC를 포함하는 모든 암호화 방법을 찾아서 출력합니다.
