Do you know if there are any C# implementations? I can't find any. With the recent client refactoring, I'm really wanting to update my private server to one of the latest builds. The versions I'd got my hands on (compared to the latest client) are all shit. My plan was to gather all the resources for several latest builds and keep hold of them until I work out the encryption... Which at this rate, is never going to happen. More of a rant than a question, lol. Any advice would be appreciated.

But since you posted it I thought why not work with it. I basically need to reverse the given function. So math. Im not quite sure how to reverse the modPow to get the var_1235 BigInteger. Its the last thing I need to have a working under-client bot (Well from the packet-side atleast :P)

And I need to find a way to use this var to get var_1235. (The code above it, the loop, is irrelevant to this question, its just there for the sake of understanding
