好的,所以下面的所有代码都不是我自己的。我一直在关注互联网上的教程,但是当我尝试并运行它时,没有看到任何密码匹配。我相信,在密码中添加密码可能会有错误,因为数据库中的密码远不及login.php脚本中描述的64个字符。我不知道。代码如下:哈希/盐渍时密码不匹配
register.php
// Create a 256 bit (64 characters) long random salt
// Let's add 'something random' and the username
// to the salt as well for added security
$salt = hash('sha256', uniqid(mt_rand(), true) . 'something random' . strtolower($username));
// Prefix the password with the salt
$hash = $salt . $password;
// Hash the salted password a bunch of times
for ($i = 0; $i < 100000; $i ++)
{
$hash = hash('sha256', $hash);
}
// Prefix the hash with the salt so we can find it back later
$hash = $salt . $hash;
// carry on with registration code...
的login.php
$email = $_POST['email'];
$password = $_POST['password'];
$con = mysql_connect("localhost", "redacted", "redacted", "redacted");
$sql = '
SELECT
`password`
FROM `users`
WHERE `email` = "' . mysql_real_escape_string($email) . '"
LIMIT 1
;';
$r = mysql_fetch_assoc(mysql_query($sql));
// The first 64 characters of the hash is the salt
$salt = substr($r['password'], 0, 64);
$hash = $salt . $password;
// Hash the password as we did before
for ($i = 0; $i < 100000; $i ++)
{
$hash = hash('sha256', $hash);
}
$hash = $salt . $hash;
if ($hash == $r['password'])
{
session_start();
header('Location: /quiz/index.php');
}
if($hash != $r['password']){
session_start();
header('Location: /?error=4');
}
// end login script
哪个教程? PHP在网上有很多低劣的教程。这似乎是其中之一。 – alex
常见的错误是数据库字段长度不足以存储所有字符。 – Konerak
啊......这就是为什么。我的密码字段只有30个字符。欢呼@Konerak :-) –
