Laravel DecryptException：'MAC 无效'

In laravel for registration I'm using encrypt algorithm for password instead of inbuilt bcrypt function in Laravel because to get password and send it to mail when password is forgot.

But decrypt it is showing a error like

DecryptException The MAC is invalid in Encrypter.php (line 184)

这个，当我运行这个代码时，它在本地服务器上工作，但在下面它不工作.我已经提到了代码，有人能帮忙吗

public function forgotpassword(Request $request)
{
  $email=$request->email;
  $selectemail = User::select('email','password','name')
     ->where('email',$email)
     ->first();     

  if($selectemail)                       
  {                                 
    $password=decrypt($selectemail->password);
    $data = array( 'email' => $selectemail->email,'password' => $password , 'name' => $selectemail->name);

    Mail::send('email.resetpassword',$data,function($message) use ($email)
    {
      $message->to([$email])->subject('Forgot Password Letgo');
    });
      echo "Mail has sent successfully";
  } else {
    echo "This email is not yet registered";
  }             
}
