Using programs like WPE/rPE you get the packets of the game but many times they are encrypteds... so how can decrypt them? what need to learn or to start to look for?.
Thx.

disassamble the game
understand the code
search the crypt algorythm
write a program to decrypt the info.
Thx you it really helped, already disassembled it and more or less understand the code, only have to look for the algorythm, but before will read some more about reverse engineering, its kinda a confusing matter.

PeiD has a plugin that detects several Encryption Methods and gives you the offsets of the code.

BP the w32_recv, depending on the game, the needed call is in reach of that function.

Yes but think that PeID only works with .exe right? And the one im trying to look into is a browser game, made in Javascript. Anyway will remember it, can be useful for others games.

Ty, gonna take an eye although its being tiring.
Sir, why the hell are you using WPE for a browsergame and trying to decrypt packets?

Boredom obviously... main reason to play a game. Seriously, there are browsergames more complex than what we probably think when mention it (a game like tetris etc.) and have curiosity for it, besides suppose that will be easier to do all this stuff in a browsergame than in the ones of download etc.

To use WPE on a Browsergame is more a hinderance than helpfull, you should atleast use something like HTTPLiveHeaders or Fiddler. A Browsergames Operates with GET/POST and in WPE it is a mess and won't record and send the whole packetlength.
Didnt know about Fiddler, will take an eye, but actually WPE used to work fine, you could sniff packets, send etc. and all worked (freeze joins, send ppl to another room, look for weapons without have to go barrel after barrel...) well and still can do it, but now only sniff the same packet every time (with just little differences, 5-6 symbols) and crypted.

You can make a filter then and replace the dynamic values, so it will ignore them and you can trigger it on any occasion you like.

Injection, crypt/decrypt and IP packets 03/13/2006 - Conquer Online 2 - 6 Replies Here are some interesting things I think. If any of you has answer, feel free to post, or PM me if you think this is not public discussion (no noob PM pls). Mod, move my topic if I'm not in the right forum ;)
1/ Is injection (through a dll and modifyed loader) in CO2 encrypted/decrypted packets possible ? About encryption and decryption of CO2 packets, I'd like to speak with unknowone, if possible.
2/ About decrypted packets : editing ./Socket.h, ./server.dat, ./ini/fuse.ini and all others...
decrypt packets for the 4th coming 07/08/2005 - General Coding - 3 Replies Hi, my question is, would the server of a game send decrypted packets ? Because I have a server for the game The 4th Coming,and I also play Conquer Online, and saw what packets can do. The 4th coming server works with a MDB (ms access) and thats where they store all their character information (eg exp,items, accs and so on) and what Im asking, can I send ap acket that would for example give me certain exp because the server does not calculate dmg,exp or anything, it just gives a certain ammount...
