예제 소스
$data = "가나다라마바사"; $crypt_pass = "abcdefghij123456"; // 16자리 $crypt_iv = "abcdefghij123456"; // 16자리 // 암호화 $endata = @openssl_encrypt($data , "aes-128-cbc", $crypt_pass, true, $crypt_iv); $endata = base64_encode($endata); echo "ENCODE DATA : " . $endata . "
"; // 복호화 $data = base64_decode($endata); $endata = @openssl_decrypt($data, "aes-128-cbc", $crypt_pass, true, $crypt_iv); echo "DECODE DATA : " . $endata . "
";
