我可能有一个愚蠢的愚蠢的问题……我正在做一个被遗忘的密码脚本(当然是登录系统),但是我被卡住了.我创建了一个具有特殊ID的代码(有效,是的！),但是我无法对其进行解密…您能帮我吗？

这是我创建特殊ID的功能：

Recovery_Script.php

include "pdo.php"; if(isset($_POST["submit"]) AND isset($_POST["ForgotPassword"])) {

$email = $_POST["ForgotPassword"];

// Check to see if a user exists with this e-mail

$sql = "SELECT email FROM account WHERE email=:email";

$stmt = $db->prepare($sql);

$stmt->execute(array(":email"=>$email));

$items = $stmt->fetchAll();

$db = null;

foreach($items as $data){

if($data["email"] == $email){

// Create a unique salt. This will never leave PHP unencrypted.

$salt = "498#2D83B631%3800EBD!801600D*7E3CC13";

// Create the unique user password reset key

$password = hash('sha256', $salt.$email);

// Create a url which we will direct them to reset their password

$pwrurl = "http://student.sps-prosek.cz/~kocvaja14/Project/SelfMade/templates/script/recovery_password.php?q=".$password;

// Mail them their key

$mailbody = "Dobrý den,\n\nJestli tento email nepatří vám, prosím, ignorujte jej. Byla vytvořena žádost o obnovení hesla na webové stránce http://student.sps-prosek.cz/~kocvaja14/SelfMade/\n\nPro obnovení hesla klikněte na odkaz níže. \n\nThanks,\nThe Administration";

mail($email, "http://student.sps-prosek.cz/~kocvaja14/Project/SelfMade/index.php - Password Reset", $mailbody);

echo "Your password recovery key has been sent to your e-mail address.";

} else

echo "No user with that e-mail address exists.";

} }?>

现在我需要创建文件,在该文件中我将解密此ID($password).但是我做不到(因为我对此东西知识不足).你能帮我吗？谢谢 ！
