Decode packets

[Gladiator*]

I've been trying to find a guide to decode login packets from main.exe to get version&serial but found nothing :/
Here is what I mean ::

You may have any packet sniffer and MU enc/dec tool. You must sniff login packet (login and pw is not necesary, you can use "login, password" for ex). When you have packet, decode it (it's C3). Last 21 characters is in order: version and serial of main. Example packet (decoded):
Code:

C3 31 F1 01 FC CF AB FC CF AB FC CF AB FC FC CF AB FC CF AB FC CF AB FC 48 63 05 00 31 30 33 31 31 61 73 64 66 61 73 64 66 61 73 64 66 61 73 64 66

31 30 33 31 31 - ASCII 10311, it's version
61 73 64 66 61 73 64 66 61 73 64 66 61 73 64 66 - ASCII asdfasdfasdfasdf, it's serial

Version from packet must be recalculated to use it in main:
Code:

Calculation in hex!!!
31 + 1 = 32
30 + 2 = 32
33 + 3 = 36
31 + 4 = 35
31 + 5 = 36

So it gives version in main: 22656

Sometimes after calculating version result is 2265:, in hex it's 32 32 36 35 3A and it's correct

P.S: this guide was made by mirraseq

Thanks for your time~
