Cannot determine server version

[Нагибатор]

Hi!
I'm following the guides to connect opencore to private server but there is a problem.
WPE Pro does not work because of anti-WPE, I guess.
So I'm using another sniffer and the first packet is something like this:

90 F5 D1 41 45 CC 8E 9E 8F 89 9F 8D 64 01 06 03  ...AE.......d...
04 05 06 07 08 09 5A F1 9D 0F 0E 0F 5A 45 A3 92  ......Z.....ZE..
D6 1A 90 C2 A5 30 BD 96 2C FA 5D 29 E3 7B 21 23  .....0..,.]).{!#
26 EA 83 EF 3A A2 B8 F5 A8 ED A2 85 80 85 8A 8F  &...:...........
B4 89 8E 83 88 8D 92 97 9C 91 96 EB 90 95 9A 9F  ................
84 99 9E 93 98                                   .....

(no login and password?!) this packet is always different, only the size is same (125 bytes)

The server's answer always

69 00 4F 00 FF 3A C5 77 11 01 1F 00 C7 78 A4 35  i.O..:.w.....x.5
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................

------------ 20 00 00 00 EF 07 00 00 00 00      ver name.........

But several bytes after 69 00 4F 00 are always different. I think this is an encryption key or other stuff.

The last problem is in the OpenCore. It sends login and password uncrypted. Something like that:

64 00 14 00 00 00 74 74 74 74 74 74 74 00 00 00  d.....ttttttt...
00 00 00 00 00 00 00 00 00 00 00 00 00 00 73 73  ..............ss
73 73 73 73 73 00 00 00 00 00 00 00 00 00 00 00  sssss...........
00 00 00 00 00 00 00

But on my server there is this random 125 bytes (see upper).

So what can I do? Maybe its easier to use an ingame bot (if it exists ofcourse)

Sorry for my rough handwrighting style.
