Mkay, so i have my packet sniffer, and am armed with the guide from the templates/tutorials sections.

i have read it, and re-read it, but the decryption seems to be lacking somwhat.

see, i can decrypt, The username packet, The Res.Dat packet, and when you get into the server, the first couple of packets (till it starts using key 3 and 4) i can get a packet saying English.

Unfortuantly, i cannot decrypt the first packet that is sent Server -> Client, becuase you need 2 counters for input and output (seperate counters) i figured setting the counter at 0 (for the first input packet, from the server) and decrypting it would work, the keys are the same, so it should decrypt the same way correct?

Examples:

Packet One Client To Server, Counters Starting At Zero:

Pre: 17 84 04 65 D5 13 C4 A5 DF 0F 33 A5 14 CB 75 6F 5F 89 B0 22 44 BE 8B A0 BD B5 8B CB C7 AE F8 B8 69 F4 01 1C C6 55 83 26 8F 05 35 AB 16 C1 7F 6D 59 87 BA 2E
After: 34 01 B4 54 65 73 9A 00 0E E0 00 00 00 07 D8 FD 78 FB 65 B5 B9 6D F3 84 DF 36 7E B7 34 56 16 76 C6 50 00 00 00 00 0E 00

Packet Two, Client To Server Counters Continuing From Before:

Pre: 5C 4C 39 A1 3A 97 54 A0 91 C2 72 62 77 DE 86 CB DA 5F B8 E6 DB 03 3F A9 10 CF 71 63

So as you can see, i should be able to decrypt the packet from the server, i can't honestly see what im doing wrong, anyone who knows better, can show me how that packet SHOULD come out, i'd be much abliged.

Note: Purpose:

Im Writing These All Up Into Vb6 Modules, Which, Once Complete, And Fully Working, Will Be Posted Up, (Maybe Sooner If I Require Help..)

Im sure sombody knows, becuase if they didn't, there would be no packet-based hacks, and no private co servers

~~Kitschi~~ · 09/17/2006, 23:19

but they r to lazy :P

fullmetalferret · 09/17/2006, 23:46

or maybe theyre too preoccupied with sorting out packet protocols on their private servers to deal with this.

= Awsome..

next stage is to work out the 3rd/4th key, and how to decode with them (its 1am when i realised how to do it so i'll do that some point this week when i have time)
and i'll post up the modules

when they are all done and ready to use.
