How to encrypt/decrypt file using luaL_loadfile()

[Dive Florida <divefloridaus@...>]

I need to parse encrypted file inside luaL_loadfile(). I know it can be done by writing my own lua_Reader(), but there are 2 issues here:

 

1. How can I free the memory returned by lua_Reader(allocated inside lua_Reader)?

2. How to know where the first block is? I need to get the key in the first block to decrypt the data.

Thanks.
