Crypt error - 'MAC is invalid.'
提问by NightMICU
A site I am developing includes a messaging system. I am encrypting messages in the table using Crypt::(). A user received a message and this error was displayed:
我正在开发的一个站点包括一个消息传递系统。我正在使用 加密表中的消息Crypt::()。用户收到一条消息并显示此错误：
exception 'Illuminate\Contracts\Encryption\DecryptException' with message 'MAC is invalid.'
in /home/forge/cvahimt.org/releases/20150601155111/vendor/laravel/framework/src/Illuminate/Encryption/Encrypter.php:147
I am encrypting the message like so:
我像这样加密消息：
// Message
$message = Message::create(
[
'thread_id' => $thread->id,
'user_id' => Auth::user()->id,
'body' => Crypt::encrypt($input['message']),
]
);
The app key is set in the .envfile and had not been changed, the message was sent just prior to the error occurring. The bodycolumn in the table is of type TEXT.
应用程序密钥设置在.env文件中并且没有更改，消息是在错误发生之前发送的。body表中的列的类型是TEXT。
Any idea what might be causing this?
知道是什么原因造成的吗？

In app.phpyou can see the following line
在app.php你可以看到以下行
'key' => env('APP_KEY', 'SomeRandomString')
Sometimes envreturns the 'APP_KEY'(reference: https://laracasts.com/discuss/channels/general-discussion/env-not-reading-variables-sometimes) value as empty, so default value is taken as "SomeRandomString"while encrypting or decrypting. So, you can replace it like
有时env将'APP_KEY'（参考：https: //laracasts.com/discuss/channels/general-discussion/env-not-reading-variables-sometimes）值返回为空，因此"SomeRandomString"在加密或解密时采用默认值。所以，你可以像这样替换它
'key' => env('APP_KEY', 'xxxxxxxxxxxxx')
where 'xxxxxxxxxxxxx'exactly matches with .envfile's APP_KEYvalue.
其中'xxxxxxxxxxxxx'与.env文件的APP_KEY值完全匹配。

Try this:
尝试这个：
composer dump-autoload
composer dump-autoload
composer clear-cache
composer clear-cache
Then, clear any seeds from your database and reseed.
然后，清除数据库中的所有种子并重新播种。
Somewhere in that process, the problem should make itself apparent if there is one.
在这个过程中的某个地方，如果存在问题，问题就会变得明显。
