如何将md5密码转换为laravel加密方法

我想将我现有的项目重新开发到laravel

在我的旧系统中，我将密码存储到md5中

现在我如何根据现有用户的laravel哈希方法转换它

有什么直接的方法吗？

不幸的是没有

---

实现这一点的唯一方法是开发应用程序的新行为（用laravel编写），允许用户使用旧的md5哈希密码登录，然后强制更改密码，或者-因为您可以在登录过程中获取用户密码-通过更新登录的用户模型，使用laravels哈希方法存储密码。

只有用户应该更改其密码（因为您看不到他们的密码）。因此，您应该为它们发送一个重置密码链接，然后使用Laravel哈希方法更新密码

有什么直接的方法吗

不，没有直接的方法，但是您可以通过覆盖

Auth/AuthController.php中的
postLogin
来实现这一点，因此它将检查密码是否为
md5
格式，然后使用laravel哈希方法重新加密，否则用户将正常连接，如：

public function postLogin(Request $request)
{
    $this->validate($request, [
        'login' => 'required', 'password' => 'required',
    ]);
    $credentials = $this->getCredentials($request);

    //Get the user
    $user = User::where('login', $request->login)->first();

    //If Hached by bcrypt
    if (Auth::attempt($credentials, $request->has('remember'))) 
    {
        return redirect()->intended($this->redirectPath());
    }
    else //Else if Hached by md5
    {
        if( $user && $user->password == md5($request->password) )
        {
            $user->password = Hash::make($request->password);
            $user->save();

            if($user->authorized){
                $user->save();

                Auth::login($user);
            }else
                Auth::logout();
        }
    }

    return redirect($this->loginPath())
        ->withInput($request->only('login', 'remember'))
        ->withErrors([
            'login' => $this->getFailedLoginMessage(),
        ]);
}

希望这能有所帮助。
这是我发现的最简单的解决方案，适用于Laravel 7

我发现这个的来源：

我当前使用的方法是密码方法的单列。我已经使用使用laravel迁移的密码列中的MD5哈希密码将我的老用户导入数据库。然后，它转换单个值。我使用的是Laravel提供的默认身份验证UI

与其他人提到的步骤相同，打开AuthenticatesUsers.php文件并将登录函数复制到LoginController.php中

在文件的顶部

加：

然后在登录函数中包含上述方法：

// check the md5 password and change md5 to bcrypt if the user was found
        $user = User::where('email', $request->email)
                ->where('password',md5($request->password))
                ->first();
        if (!empty($user->id)) {
            $user->password = bcrypt($request->input('password'));
            $user->save();
        }
