Php 如何在Laravel 8中解密Cookie

最近，我们将Laravel应用程序从5.6升级到Laravel 8.18.1。我们在RouteServiceProvider.php中使用cookie解密

HomeController.php

$encrypter = app(\Illuminate\Contracts\Encryption\Encrypter::class);
$channel_cookie = $encrypter->decrypt(Cookie::get('channel')); // result "mobile"

$encrypter = app(\Illuminate\Contracts\Encryption\Encrypter::class);
$channel_cookie = $encrypter->decrypt(Cookie::get('channel')); // result "a86aa854d5e61e2873acd30373b6725e36fba671|mobile"
$channel_cookie = explode("|",$channel_cookie)[1]; // result mobile

Cookie：：队列（“频道”，“移动”，60241）；//通道加密 价值观= EYJPDII6IJJVTGFZZZHDEOXPJMK9VTGFFYMLSBXC9PsiSinZHbHbLijioid0DJMW9ZbHbFfqTk5AVXBDZ09IIWIBWfjijoiZGM4U1YTY0ZVKNTE4NJBLNZG4NZZZZZWmZZWnjdJdKNgNgGyZIwM3MJ9

在Laravel5.6中，它直接将散列解密为一个值

RouteServiceProvider.php

$encrypter = app(\Illuminate\Contracts\Encryption\Encrypter::class);
$channel_cookie = $encrypter->decrypt(Cookie::get('channel')); // result "mobile"

$encrypter = app(\Illuminate\Contracts\Encryption\Encrypter::class);
$channel_cookie = $encrypter->decrypt(Cookie::get('channel')); // result "a86aa854d5e61e2873acd30373b6725e36fba671|mobile"
$channel_cookie = explode("|",$channel_cookie)[1]; // result mobile

在Laravel8.18.1中，它将散列解密为带有竖线的值

RouteServiceProvider.php

$encrypter = app(\Illuminate\Contracts\Encryption\Encrypter::class);
$channel_cookie = $encrypter->decrypt(Cookie::get('channel')); // result "mobile"

$encrypter = app(\Illuminate\Contracts\Encryption\Encrypter::class);
$channel_cookie = $encrypter->decrypt(Cookie::get('channel')); // result "a86aa854d5e61e2873acd30373b6725e36fba671|mobile"
$channel_cookie = explode("|",$channel_cookie)[1]; // result mobile

这是在Laravel 8中解密Cookie的安全解决方案吗？

您找到了更好的方法吗？这是一种非常奇怪的解密方式，但我也找不到其他解决方案。
