[Question]Public & Private keys

I've seen in a popular forum, one person called HolySword. He was talking that took aimbot, so he needed his conquer.exe and MsgServer.exe in this case was binary server. I use CoEmu source, I wonder how he does to make the old exe stop working, and people can only log in with the new exe. Searching on www.google.com, I found some things about Private and Public Keys do not know if this is right, or has some things on.
Note: I already have OllyDbg, and must figure out how to do this encryption.
Please only post helpful things, I wont you make it for me. Only need to know for do it myself. That should help many peoples.

OllyDbg:

1) Open Conquer.exe
2) Make sure your in the conquer module
3) search referenced text strings for "DR654dt34trg4UI6"
4) change every reference to the key of your choice

If your using source files, just search for the key, and replace it there also :)

Ok, thank you it worked with source. But if it was a binary... the key will be the same? because i can't find this "DR654dt34trg4UI6" in MsgServer.exe and conquer.exe, I think it will be changed each version.

I think the crypt key for binary and exe source, isn't the same.

bump.
I want to know too, how should be called revive counts.. "string"?

They are the same (in Conquer, and MsgServer) but MsgServer (the newer 509x or whatever versionafter 5065) is packed so olly can't extract strings until after it's unpacked. Have fun unpacking the exe, and by that, I mean having someone explain to you how to do it (Cause I'm sure as hell not going to due to how complex it can get, and nobody here on E*PvP actively a sides from unknownone would be able to help you so gg). There are other methods around editing the key with olly though -- even if its packed.

Thank you hybrid, I'm studying so willing to protect my server, and fuck some binary server that i hate. This is so hard... Now I'm searching on CE the place of revive, isn't easy, it found 30.000 things about "20" seconds of revive lol. Thanks for who is helping me.
