Files in rappelz are encrypted that way:

keyTable[0x100] =

foreach byte in file do
decryptedByte = keyTable[position_in_file mod 0x100] xor byte;
next

the encryption is exactly the same algorithm as decryption, so encrypt an encrypted file would result in a decrypted file.
this keyTable is sometimes redundant in data.00x files, and it mean that there is many 0s encrypted (0 xor something = something)

hope this help

PS: it's stupid to always work on something that someone has already done, this remind me open-source vs proprietary programs ....

PS2: data.000 is encrypted that way, and contain all file position in data.00x using this:
1 byte : file_name_length
file_name_length bytes: file name (using "hash", that's not the real filename)
4 bytes: file position in data.00x
4 bytes: file size

i'm currently working on these "hash", they are so ugly i already discovered some things about it but not finished yet, going to have hard time to disassemble but IDA pro help alot

[ptifou78]

Thanks a lot for that i just want to know how do you have found the keyTable


Really good information good job to you

[glandu2]

i openned a data file (like data.001) with an hex editor and see that at some places, these chars are redundant, so i test several combination beginning with simple add, i was almost sure that these redundant bytes were all the same and were 0s (because 0 is most likely to be use as padding or something else), but adding was not the right guessing, i tested xor as i already used it to encrypt some information without much effort and it appear to be the right thing to do, also has to use a loop to shift the table because i did'nt found the right table in one attempt, the table when i found it was not aligned ... but thanks human to not use only unreadable binary in data files

[ptifou78]

Thanks for your explain

[glandu2]

i found some programs that convert hash to name (called folder2name), this program, made by Xijezu, will greatly help me, i will do some reverse engineering as no one want to explain the algorithm, and thanks Xijezu () to use .net framework there are many decompiler for that type of programs, no need to disassemble, great

Doing this, i must thank you very much for your job (even if you don't seems to want someone not in your team to have access to this knowledge of rappelz internals) because i don't see what i would do to find name <-> hash algorithm

i think i will use plugin system to implement somethings, i don't like GUI so much in C/c++ (and i hate absolutly .net framework, it's slow and is a java-like fail, using CIL to make portable application between only microsoft platform it's a pity :/)

Fail only skins changed and all says xsandu is genies ! FAIL...

I have done Total commander plugin, here are sources & binaries:

A guide for what? The Resources?

Open your Rappelz folder and copy them into you Resource Folder...^^

[Tofrum]

im sure XSanuDu leeched them like THEY LEECHED AND STOLE VENDETTA REPACK, yeah thats right, vendetta worked hard for 2 weeks, then baaam, some files was transfered and host not paid, just like they did to some one else i know :P
