问题描述

我正在将旧版应用移植到 Laravel.旧的应用程序使用 MD5 来散列密码而不加盐，所以我需要在 Laravel 中复制它.作为记录，我们正在使用 salt 将密码更改为 bcrypt，但这不是一个简单的过程，需要用户登录才能这样做 - 同时我只需要使用旧哈希登录即可.

I'm porting over a legacy app into Laravel. The old app used MD5 to hash the passwords without a salt, so I need to replicate that within Laravel. For the record, we are changing the passwords to bcrypt with a salt, but it's not a simple process and requires a user login to do so - for the meantime I just need to get logins working with the legacy hashes.

我已按照本指南将 Auth::hash 转换为 MD5:如何在 Laravel 4 中使用 SHA1 加密而不是 BCrypt?

I have followed this guide to convert Auth::hash to MD5: How to use SHA1 encryption instead of BCrypt in Laravel 4?

当我在注册帐户时以纯文本格式打印密码和在我的 make 方法中生成的哈希值时:

When I print out the password in plain text and the generated hash in my make method when registering an account:

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.但是，当它被保存到数据库时，我得到了一个完全不同的哈希值.我的猜测是 Laravel 正在其他地方添加密码，但我找不到在哪里以及如何覆盖它.

Great, that's what I need. However, when that is saved to the database I get a different hash entirely. My guess is that Laravel is salting the password elsewhere, but I can't find where and how to override this.

我在 app/libraries 中的 MD5Hasher.php 文件:

My MD5Hasher.php file inside app/libraries:

<?php
class MD5Hasher implements IlluminateContractsHashingHasher {

    /**
     * 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 IlluminateSupportServiceProvider {

    /**
     * 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 AppHttpControllersAuth;

use Hash;
use AppUser;
use Validator;
use Mail;
use AppHttpControllersController;
use IlluminateFoundationAuthThrottlesLogins;
use IlluminateFoundationAuthAuthenticatesAndRegistersUsers;

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 IlluminateContractsValidationValidator
     */
    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;
    }
}
