Question

由于某种原因索引.php不起作用。这是我的代码。我正在使用http://aesencryption.net/#PHP-aes-encryption-example

上的示例

    <?php
    include 'AES.php's;
    $inputText = "My text to encrypt";
    $inputKey = "My text to encrypt";
    $blockSize = 256;
    $aes = new AES($inputText, $inputKey, $blockSize);
    $enc = $aes->encrypt();
    $aes->setData($enc);
    $dec=$aes->decrypt();
    echo "After encryption: ".$enc."<br/>";
    echo "After decryption: ".$dec."<br/>";
    ?>

由于某种原因，它给了我一个404

Answer 1

在第一行中，您使用了include 'AES.php's;更改为include 'AES.php';我已使用您提供的示例进行了检查，并在更改错误语法时使用了该文档

<?php
include 'aes.php';
$inputText = "My text to encrypt";
$inputKey = "My text to encrypt";
$blockSize = 256;
$aes = new AES($inputText, $inputKey, $blockSize);
$enc = $aes->encrypt();
$aes->setData($enc);
$dec=$aes->decrypt();
echo "After encryption: ".$enc."<br/>";
echo "After decryption: ".$dec."<br/>";
?>

根据您的示例http://aesencryption.net/#PHP-aes-encryption-example

，aes.php以下

Answer 2

由于某种原因索引.php无效。

这不是很有帮助。

我正在使用http://aesencryption.net/#PHP-aes-encryption-example
上的示例

不要使用该代码。 Use an well-studied encryption library instead
