android密码sha256解密,使用password_hash和SHA256加密和解密

我有两个脚本，一个是verify.php和一个register.php。使用password_hash和SHA256加密和解密

在我的注册页面，我用这个..

$salt = hash('sha256', uniqid(mt_rand(), true) . $email);

$storedHash = $salt . $password;

for ($i = 0; $i < 50000; $i ++)

{

$storedHash = hash('sha256', $storedHash);

}

$sql = "INSERT INTO authentication (email, password, fname, lname, created_at) VALUES ('$email', '$storedHash', '$fname', '$lname', '$today')";

这里是我的用户登录类..

include 'dbinclude.php';

// Class User

class user {

var $username;

var $password;

var $hashed;

var $salt;

function loginUser() {

require 'dbinclude.php';

$sql = "SELECT * FROM authentication WHERE email='" . $this->u
