如何在Laravel中对密码使用MD5哈希


How can I use MD5 hashing for passwords in Laravel?

我正在将一个遗留应用程序移植到Laravel中。旧的应用程序使用MD5对密码进行无盐散列,所以我需要在Laravel中复制它。记录在案,我们正在用salt将密码更改为bcrypt,但这不是一个简单的过程,需要用户登录才能完成——与此同时,我只需要使用遗留哈希进行登录。

我遵循本指南将Auth::hash转换为MD5:如何在Laravel 4中使用SHA1加密而不是BCrypt?

当我在注册帐户时用明文打印出密码和make方法中生成的哈希时:

public function make($value, array $options = array()) {
    echo $value.'<br>'.hash('md5', $value);
    exit;
    return hash('md5', $value);
}

我得到以下信息:

123456
e10adc3949ba59abbe56e057f20f883e

太好了,这正是我需要的。然而,当它被保存到数据库中时,我会得到一个完全不同的散列。我的猜测是Laravel在其他地方添加密码,但我找不到在哪里以及如何覆盖它。

我在app/libraries:中的MD5Hasher.php文件

<?php
class MD5Hasher implements Illuminate'Contracts'Hashing'Hasher {
    /**
     * Hash the given value.
     *
     * @param  string  $value
     * @return array   $options
     * @return string
     */
    public function make($value, array $options = array()) {
        return hash('md5', $value);
    }
    /**
     * Check the given plain value against a hash.
     *
     * @param  string  $value
     * @param  string  $hashedValue
     * @param  array   $options
     * @return bool
     */
    public function check($value, $hashedValue, array $options = array()) {
        return $this->make($value) === $hashedValue;
    }
    /**
     * Check if the given hash has been hashed using the given options.
     *
     * @param  string  $hashedValue
     * @param  array   $options
     * @return bool
     */
    public function needsRehash($hashedValue, array $options = array()) {
        return false;
    }
}

我的MD5HashServiceProvider.php:

<?php
class MD5HashServiceProvider extends Illuminate'Support'ServiceProvider {
    /**
     * Register the service provider.
     *
     * @return void
     */
    public function register() {
        $this->app['hash'] = $this->app->share(function () {
            return new MD5Hasher();
        });
    }
    /**
     * Get the services provided by the provider.
     *
     * @return array
     */
    public function provides() {
        return array('hash');
    }
}

我的AuthController.php如下所示:

<?php
namespace App'Http'Controllers'Auth;
use Hash;
use App'User;
use Validator;
use Mail;
use App'Http'Controllers'Controller;
use Illuminate'Foundation'Auth'ThrottlesLogins;
use Illuminate'Foundation'Auth'AuthenticatesAndRegistersUsers;
class AuthController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Registration & Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users, as well as the
    | authentication of existing users. By default, this controller uses
    | a simple trait to add these behaviors. Why don't you explore it?
    |
    */
    use AuthenticatesAndRegistersUsers, ThrottlesLogins;
    //protected $redirectTo = '/account';
    /**
     * Create a new authentication controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest', ['except' => 'getLogout']);
    }
    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return 'Illuminate'Contracts'Validation'Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|confirmed|min:6',
        ]);
    }
    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    protected function create(array $data)
    {
        $this->redirectTo = '/register/step-1';
        $user = User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
        ]);
        // email the user
        Mail::send('emails.register', ['user' => $user], function($message) use ($user)
        {
            $message->to($user->email, $user->name)->subject('Edexus - Welcome');
        });
        // email the admin
        Mail::send('emails.register-admin', ['user' => $user], function($message) use ($user)
        {
            $message->to('admins@***.com', 'Edexus')->subject('Edexus - New user sign up');
        });
        return $user;
    }
}

查看用户模型中的密码转换器。在控制器中对密码进行哈希处理后,它将再次对其进行哈希处理。

我的建议是在creating()和updating()模型事件中散列密码一次,然后将其从赋值函数和控制器中删除。

步骤1:创建应用程序/库文件夹并将其添加到composer的自动加载中。classmap

"autoload": {
    "classmap": [
        // ...
        "app/libraries"
    ]
},

步骤2:在app/libraries中创建两个php文件MD5Hasher.php和MD5HashServiceProviderMD5Hasher.php

<?php
namespace App'Libraries;
use Illuminate'Contracts'Hashing'Hasher;
class MD5Hasher implements Hasher {
    /**
     * Hash the given value.
     *
     * @param  string  $value
     * @return array   $options
     * @return string
     */
    public function make($value, array $options = array()) {
        return md5($value);
    }
    /**
     * Check the given plain value against a hash.
     *
     * @param  string  $value
     * @param  string  $hashedValue
     * @param  array   $options
     * @return bool
     */
    public function check($value, $hashedValue, array $options = array()) {
        return $this->make($value) === $hashedValue;
    }
    /**
     * Check if the given hash has been hashed using the given options.
     *
     * @param  string  $hashedValue
     * @param  array   $options
     * @return bool
     */
    public function needsRehash($hashedValue, array $options = array()) {
        return false;
    }
}

MD5HashServiceProvider.php

<?php
namespace App'Libraries;
use Illuminate'Support'ServiceProvider;
class MD5HashServiceProvider extends ServiceProvider {
    /**
     * Register the service provider.
     *
     * @return void
     */
    public function register() {
//        $this->app['hash'] = $this->app->share(function () {
//            return new MD5Hasher();
//        });
        $this->app->singleton('hash', function () {
            return new MD5Hasher();
        });
    }
    /**
     * Get the services provided by the provider.
     *
     * @return array
     */
    public function provides() {
        return array('hash');
    }

步骤3:隐藏或删除config/app.php中的"Illuminate''Hashing''HashServiceProvider::class",并添加"app''Libraries''MD5HashServiceProvider::class"
