东方深秘录解包工具源代码【需对应修改】
出于我并不是th135pak的作者，我没法直接发所有源文件以下提及的函数需要在Riatre大神的th135pak中对应修改才能使用。
本来以为黄昏在正式版当中封入了文件名，，，，结果并没有。。。
我跑了个彩虹表，，，能有3、4千文件名，，，，实在跑不动了。。。。。
以下代码请在有限范围内任意使用。。。
话说我要不要挂一份去github。。。

} {:16_458:}本来是自己写了一段代码的，结果一看正式版的封包比起web版又改了，又回到了古老的模式，，，我干脆就又用th135pak的代码做基础改了。。。
丧病的黄昏体验版里对RSApublicKey的加密在正式版里居然没了。。 要找文件名的话，还不如过一遍脚本里面的字符串来得快 文件名我直接扒内存找了 文件名我直接扒内存找了 哇，大触！技术群里新来的那位特地在群里问起您了…… 为何不直接丢到GitHub呢
