CO clients some(great) help

Hey folks
I have had moderate experience in programming over the past years
but I still need some (great)help from people here who had great experience in this part

I'm a C++ & C# programmer i can rate myself as 6/10
Let's not get out of context , i have hooked Send&Recv in CO.exe

but when I print the packets, it seems crypted some how

So I need help with notes or references about encryption (especially old clients)
Already Packet 1086 ( MsgAccount ) has been done
but I can't do the same for the other ones
I will appreciate all assistance, no matter how large it is

You should be more specific if you want help...

We don't know what you're dealing with
- client version?
- bytes of the packet?
- What makes you think it's "encrypted"?
- You say packet 1086 is finished, that would mean your reading/sending "Decrypted" packets?

Thanks for your appreciate
it's my bad not to mention any minor details

i'm working on V5065
I cannot parse packets , just need hints about algorithms used by TQ

Cause i hook the send function , sure this function passes the crypted packets to Servers then Server do the decryption then send it back to client etc...

Packet 1086 is decrypted successfully
but can't parse packet 1010 !
I don't know whether I made it clear or whether I made it more dificult

The encryption happens in the client, you should go back in a dissambler and find that sub routine.
