Packet Analyzing

[sky_dragon]

Does anyone have experience with analyzing BDO's packets with Wireshark or some other program?

[KronaFlyff]

If you find someone that does, can you let me know? I'm wanting a bot constructed and I'm willing to pay.

here is a guide that help me with a lot of games

Are encrypted

[sky_dragon]

Yes they're encrypted, I'm asking if people have experience decrypting the packets.

[R3p]

decrypting them out of the box? not possible cause bdo uses an xor chain

u cant decrypt a single packet from within the chain. u have to decrypt all of them from first to last

[sky_dragon]

By chain, do you mean a chain per client, or is there one chain for the whole server? The latter makes it seem impossible.

Also, some of the packets have plain readable text in them, does this mean anything?

[R3p]

a chain/handshake between client and server unique per connection

server messages are 99,9% not encrypted

client messages are 100% crypted

[sky_dragon]

What about the packets used for enhancing. Can they be decrypted or modified?

[R3p]

no cause enchant is server sided

[sky_dragon]

I found something in the game with client-sided RNG (it's not weapon enhancing, but still useful).
If I block packets where the RNG is a fail then this could ensure the server only gets success packets. Would this be possible?

[0xG00DF00D]

U don't understand that the success or fail isn't processed client sided. A packet is send with the enchant request and the server decides if it fails or not

[sky_dragon]

The important things like enhancing are obviously server-sided. Not every little thing that's RNG is server-sided, there would be way too much lag and waster of server resources.

what exactly are you trying to do?

also, you can learn a lot from the emulator that got leaked, look into that before proceeding since that essentially answers your main question
