Title: Decrypting tech tree from SHEETS.VOL
Post by: leeor_net on September 15, 2004, 04:04:16 PM
Welp, I've done some work and now I have a bunch of TXT files extracted. Clearly, however, they are either encrypted or simply not TXT files.

How can I read the file so that it makes sense?

They are text files encoded with an algorithm similar to Huffman encoding.

If you want a copy of some decompressed sheets PM here or in IRC.

(I'm not giving out the decompression algorithm, sry but I will give you a decompressed copy.)

A decompressed sheets.vol file has been posted in the file forums (Sheets.vol thread (http://forum.outpostuniverse.net/index.php?showtopic=993)). You can extract plain text from it using the revolver. There is a slight problem though in that the revolver doesn't extract one of the files properly (0 bytes) but that file is posted later in the thread.

Thanks for the heads up!

Why is it that you're not giving out the algorithim? I'm just wondering, not necisarliy asking for it (god my spelling is off!)

Because people will abuse it in multiplayer.

I think it's probably a good idea to keep it a secret. It could be used to protect files in future releases from prying eyes (although a compression algorithm has never been written yet afaik). Besides, the only thing that is currently compressed are the sheets files, but a decompressed version has been distributed so there is no need to tell anyone the decompression algorithm.
