Packet Encryption? Boom Online / PopTag! / Crazy Arcade

[~Luca~]

Hello

I am playing around with Boom Online packets using WireShark (I'm in no way skilled enough to fully create a server emulator but I'm just trying to learn and such), and I know that the packets would be encrypted, but I'm looking into if it's reversible or how it works.

So basically I know which packets are from the game because it's based in Vietnam, so I tracked the IP to find which one is of the game, and applied a Wireshark filter accordingly.

I sent two chat messages, "aa", and "ab", and took the outbound packet to the server, and I guess because of the encryption it's very weird and not possible to tell what part of the packet does what. So here's the packets

aa

0000   30 46 9a 81 41 b3 fc aa 14 2e 21 57 08 00 45 b8  0F..A.....!W..E.
0010   00 35 63 d2 00 00 80 06 00 00 0a 00 00 02 78 8a  .5c...........x.
0020   4d 56 d5 3b 1e c6 c2 32 c2 2f 1e d3 fc 6d 50 18  MV.;...2./...mP.
0030   01 04 d0 09 00 00 15 a6 a5 61 05 67 6f 08 bd 7f  .........a.go...
0040   f7 bc 2e

ab

0000   30 46 9a 81 41 b3 fc aa 14 2e 21 57 08 00 45 b8  0F..A.....!W..E.
0010   00 35 63 cc 00 00 80 06 00 00 0a 00 00 02 78 8a  .5c...........x.
0020   4d 56 d5 3b 1e c6 c2 32 c1 fc 1e d3 fc 2f 50 18  MV.;...2...../P.
0030   01 04 d0 09 00 00 1a a6 a5 61 0a 67 6f 08 cc 7f  .........a.go...
0040   f4 bc f0

(these were sent like 5-10 seconds apart)

But the header for all packets sent by my client are 30 46... so it just makes it more confusing. Again I'm almost completely unsure how this works, so if anyone could help with a bit of explanation that would be amazing

Thanks!
