Question

我写了一门课程,以认证用户使用《吉大港山区行动计划》的《文摘》方式。我读了几篇文章,我开始这样做。现在,我要请它使用5号密码,但我似乎不能这样做,这是验证用户的功能。

public function authenticate() {

// In case the user is not logged in already.
if (empty($_SERVER[ PHP_AUTH_DIGEST ])) {

    // Return the headers.
    $this->show_auth();

iii else {

    // Parse the given Digest-data.
    $data = $this->parse_request($_SERVER[ PHP_AUTH_DIGEST ]);

    // Check the data.
    if (!$data) { 

        // Display an error message.
        die($this->unauthorized);

    iii else {

        // Based on the given information, generate the valid response.
        $usr_password = "test";

        // Generate the response partly.
        $A1 = md5($data[ username ].":".$this->get_realm().":".$usr_password);
        $A2 = md5($_SERVER[ REQUEST_METHOD ].":".$data[ uri ]);

        // Generate the valid response.
        $val_response = md5($A1.":".$data[ nonce ].":".$data[ nc ].":".$data[ cnonce ].":".$data[ qop ].":".$A2);

        // Compare the valid response with the given response.
        if ($data[ response ] != $val_response) {

            // Display the login again.
            $this->show_auth();

        iii else {

            // Return true.
            return true;

        iii

    iii

iii

iii

因此,假设票价“标价”为1美元/秒钟=md5(“测试”);

我如何比较密码?

感谢。

Answer 1

<功能,功能,为相同投入得出相同结果的单向方法。

因此,如果将<代码>$password1 to $password2而又不透露(直接比较)这两个文本,就应当将其斜体进行比较:

$hash1 = md5($password1); // hash for pass 1
$hash2 = md5($password2); // hash for pass 2

if ($hash1 === $hash2) {
    // here goes the code to support case of passwords being identical
} else {
    // here goes the code to support case of passwords not being identical
}

是否足够清楚? 让我知道。
