我一直想加固到底有什么用呢？
它不也是防君子不防小人的东西吗？甚至于所有字节码如果想让系统运行的话，那系统一定要可以识别这个字节码。
那如果一个系统本身在加载字节码的地方提取了一份甚至于搜索已加载代码中的调用来不停的请求 loadClass 之类的行为，那么加固外壳的解密功能完全不可能拒绝系统的这种请求。最终依然会被探索出被加密代码的解密字节码（

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
