I guess the packet is encrypted. You have to decrypt it.
SilkroadSecurity API is working fine.

E: I checked the bitmask. It seems that the packet is not encrypted. Are you sure that the packet is a correct one?

Joymax did a bad job at some points as it seems
Some time ago I used wireshark to capture some packets and noticed that some contain data from older ones
length and everything is fine, except that the server sends more data than it needs to
no idea why, though

Just remove the **** from the end and you'll be fine

The server sometimes send multiple packet data in one packet. They do not send more data than required.

Are you sure it's older data? TCP is a streaming protocol, so it's possible that one physical TCP message contains more than one logical SRO packet.

I saw data from an older(obviously longer) packet there
no structure of a new one
So I would say yes, it's from an older packet

Hallo, hab mal eine Frage die aber eher etwas weitgehend ist. Ich möchte ich ein Tool entwickeln das die IP´s auflistet mit der sich ein Programm verbindet. So etwas wie bei NetLimiter, nur nicht für alle Prozesse sondern für einen. Dann sollte es noch Verbindungen trennen können. Könnte man zB mein AutoIt Programm in Verbindung mit WinPcap bringen?
