Thread: [Help] Ragnarok Online OpenKore Bot Encryption

Hallo...

Currently i play Ragnarok Official...
Before last month update gameguard..
I can find encryption kry because they use simple XOR encryption...

But after patch the have kind a wierd encryption...i think it was xorshift/lfsr but after some testing i cant figure it out what type encryption they used..

I try to unpack dll using themida but im failed to unpack @dwar if u can help me to learn how to unpacking and how to find encryption method it should be great..

I still can use openkore BOT with injecting real client session into bot client..

But i think i need to find what encryption they used..
Because i just want to learn about it..
