QQ2003 agreement on the structure of the KeepAlive

Baotou
QQ number is 4 bytes and then
Then, a confidential papers?
16 secret is that the length of the text, how to be?

Qq numbers are encrypted string? Why not 16 bytes instead of 24 bytes encrypted ah?
Depressed, help me!

After a 24-byte encryption what you

Encryption is the process that encrypt
For example,
Encryption "27770163" keys used sessionkey
Is the outcome of a 24 byte

I would like to know the 16-byte secret 2003 agreement KeepAlive how the text? ? ?

Who encrypt process

He wants to develop third-party QQ Win bars, because that is written in C language, OpenQ encrypt the process.

Luma Brother you a direct answer that question better Mody
That process does not encrypt the same and you LumaQQ Mody my OpenQ the Crypt.java

Luma help explain the structure of your big brother!

/**
* "Pre>
* Keep Alive packets, the packet format is
* 1. Head
* 2. QQ user encryption No. 4 bytes. In fact, this part can be arbitrary, indifferent (gaim qq said, not tested)
* 3. Tail

* If Ma Jieauthor
*/

7 byte head, I know that the tail is a byte, plus a piece of 8 bytes
Then the middle enclaves how only four bytes? ? ? QQ number is the Hex? ? ?
I caught the lumaqq keepalive packets is not so simple ah? ? ?
Mody said enclaves could elaborate, I would like to thank the ~~~~
