no intention on giving up i really want to push us into new possibles etc ... a few people tried to start a group to do this but they seemed to have flopped so its my turn lol

yea ... its interesting how it does that lol ... with co you just change the packet type so its gonna need a bit of a rework with that but ill get there lol

it is? to me any encryption is like ugh lol

It has a 4Byte XOR encryption of (A1 87 A9 8F) on your first line then (A1 8B A9 83) on your second line and so forth this continues or I guess you could say a 32 byte XOR of (A1 87 A9 8F A1 87 A9 8F A1 87 A9 8F A1 87 A9 8F A1 8B A9 83 A1 8B A9 83 A1 8B A9 83 A1 8B A9 83)

If you're not too sure about what this means just select the data you wish to XOR in winhex then somewhere there is a spot where you can do a calculation or something select XOR and input the 4bytes worth

to be honest even telling me that i have no idea what your saying lol! ... i think i needa read up on in


EDIT: There is now updates on the game server progress added to the first post

[funhacker]

ok XORing a byte of data will + or - the amount off the byte in question

Example
Encryption of FF and I had the following

20 (encrypted number)
I now do an Xor of FF
I get DF (this can be done with Win7 Programmer Window)
So the official number is 223

i get the single byte stuff (modify data in winhex) but it is more the whole key that i get the issues with .... but the packet length don't look right ... idk if im doing it wrong or something though ... it only allows a 2 characters for the xor in that option

[forcer]

did you actualy look at old EO sources I have released? it might be very helpful in packet reverse-engineering..

btw: finally I see someone doing something useful here, send me a message on IM if you need some help.

i have looked at it but to tell ya the truth they aint helped me much yet (i guess i aint read them enough though)

EDIT: do you know where exactly the packets are handled (in which project would be a good start for me )

as a side note forcer did you used to be called blacknull lol? i just found something interesting in the source mentioning blacknull and acme

I have never used a built in function for encryption keys I have usually done my own functions

thats fine lol ill just work on a crypto for the server itself

That's how easy it is to decrypt files

look in AccountServer/EncryptServer.h
there might be more, just search in all .cpp and .h for "encrypt" or "decrypt"

blacknull? I don't think it's a nickname of someone I know... "soul.exe blacknull" is only case I can think of.

look in AccountServer/EncryptServer.h
there might be more, just search in all .cpp and .h for "encrypt" or "decrypt"


blacknull? I don't think it's a nickname of someone I know... "soul.exe blacknull" is only case I can think of.

thats what im talking about btw forcer

Could I make a suggestion hio? Since imo writing up the server binary files so they are open source requires almost as much work as making one of your own. Why not make our own Client/Server/Database setup. Honestly there is soooo much wasted space with EO it was poorly put together.. It has no functionality with multiple screen resolutions.. And we will still be limited to what official EO releases.

The plus side to making our own c# version of EO is for one there is a very nice package by Microsoft called XNA which makes programming with Direct X sooo much easier. Collisions and such are easily calculated and it has a basic game loop setup already for you. The biggest time cost these days in games are Graphics and Concept.. both of which are supplied by a EO client... XNA handles .dds files no problem at all I am sure if we rubbed up forcer enough he may be willing to ask that friend of his to write a little DLL file for loading .c3 files as workable mesh files or we could just convert them all to .3ds files..

Just I have a much better map design system then TQ ever had.. their's is **** over loaded and just another waste of space >.> I already have files like pathfinder and levexp sorted out and shop.dat itemtype.dat INI files it would require very little work compared to writing your own game just an idea I know I would be willing to spare some time when ever I had it to work on this it might bring me back to EO pserver community a little more full on

it is a pretty good idea in many ways just one massive task lol ... a full client rewrite may aswell be making a whole new game

i just don't know if ild have the knowledge to be able to help out very much with it lol

i aint done much gfx work in the way of programing at all .. mainly just in making servers and stuff

but it may be a option we can certainly look at



and it would be a legal way lmfao
