Question

我尝试加密我的文件，然后使用move_upload_file函数移动我的文件。如果没有加密功能，我可以上传我的文件。但是我的问题是我需要它加密我的文件然后上传。有人知道这个问题吗？请帮助。...

$newname = dirname(__FILE__).'/upload/'.$filename;

if (!file_exists($newname)) {
    $ALGORITHM = 'AES-128-CBC';
    $IV    = '12dasdq3g5b2434b';
    $password = '123456';

    $contenuto = file_get_contents($_FILES['uploaded_file']['tmp_name']);

    $contenuto = openssl_encrypt($contenuto, $ALGORITHM, $password, 0, $IV);
    $filename  = $filename . '.crypto';

    if (move_uploaded_file($contenuto,$newname)) {
        echo "It's done! The file has been saved.";
    } else {
        echo "Error: A problem occurred during file upload!";
    }
} else {
    echo "Error: File ".$_FILES["uploaded_file"]["name"]." already exists";
}

未测试您需要使用file_put_contents作为返回的字符串

$newname = dirname(__FILE__).'/upload/'.$_FILES['uploaded_file']['name'].'.crypto';
$tempfile = $_FILES['uploaded_file']['tmp_name'];
if (!file_exists($newname)) {
    $ALGORITHM = 'AES-128-CBC';
    $IV    = '12dasdq3g5b2434b';
    $password = '123456';
    file_put_contents($tempfile, openssl_encrypt(file_get_contents($tempfile), $ALGORITHM, $password, 0, $IV));
    if (move_uploaded_file($tempfile,$newname)) {
        echo 'It\'s done! The file has been saved.';
    } else {
        echo 'Error: A problem occurred during file upload!';
    }
} else {
    echo 'Error: File '.$_FILES['uploaded_file']['name'].' already exists';
}

快速浏览文档显示https://www.php.net/manual/en/function.openssl-encrypt.php openssl_encrypt返回一个加密的字符串，而不是文件。您需要将结果保存到文件中，然后将其移动到新的目的地。

可以上传加密文件吗？
