Hi Luigi,

Since the last time I asked you questions about your camfrog login tester, I've been studying a lot about socket programming and C programming in general and now I can understand most of your code. Thank you so much for inspiring me.

Here comes the questions:

After recieving key from camfrog login server, you build the packet, encrypt it, and send it to the server. I understand that you know how the login information packet is constructed by reverse engineering the camfrog client. Can I achieve this with out reversing? ie. Using the tools you provided, is it possible to know how other packets (registration request, IM, chatroom joining request, etc.) are constructed? If it's possible, could you please provide me some guide on how to achieve this?

Any help would be highly appreciated,
Pat

PS. Sorry for my bad English

uhmmm it's not a quick thing for various reasons.
anyway an idea could be monitoring the encryption and decryption functions and the one for setting the password (a job for ollydbg or a custom hooker) and checking the sniffed connections in real-time.
if it can be useful I have seen that here are still saved some breakpoints from version 5.1.0.129: 00422135 and 0045ae70 (this one should be the AES password but don't know because I remember nothing of this stuff)
