PHP AES 암호화 (Cipher)

string openssl_encrypt ( string $data , string $method , string $password [, int $options = 0 [, string $iv = "" ]] )

string openssl_decrypt ( string $data , string $method , string $password [, int $options = 0 [, string $iv = "" ]] )

$data = 파일이나 텍스트같은 데이터

$method = 암호화 메소드 

$password = 암호화키

$option = OPENSSL_RAW_DATA(1 or true) OPENSSL_ZERO_PADDING(0 or false)

$iv = cbc를 사용할때 첫번째 암호화 블럭

$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 . "<br>";

// 복호화
$data = base64_decode($endata);
$endata = @openssl_decrypt($data, "aes-128-cbc", $crypt_pass, true, $crypt_iv);
echo "DECODE DATA : " . $endata . "<br>";
