What packet encryption is the EQEMU implementing?

[KLS]

The data steam is not encrypted to my knowledge, portions of it are compressed using zlib however.

[mcox05]

where is the portion of the code where sending the packets across networks is actually done. I'm specifically trying to locate chat packets (tells, shouts, ooc, etc..). Anything would be very helpful.

I don't know offhand but I'll try to find it later tonight for ya.

if you find out then you are an angel

Any update on finding the code segments that deal with the compression? thanks

So youre trying to be able to spy on peoples conversations. How nice. Should we call you George?

People have an expectation of privacy in their communications, so you could be openning yourself to legal issues and if someone does bust you spying on them, I hope they do persue it to the fullest extent of the law.

Its bad enough our goverment is spying on us without any regards to our rights and you adding to that isnt going to gain you any friends.

I swear people like you seem to exist in every division of this world, be it forums, family, or in the classroom.

Thank you so much for you near-sighted thoughts. How about you stick to just playing the game and not wasting my time you moron.

There are many different reasons to want to monitor chat packets on the EMU than just petty privacy theft .... (what in the world would be so important and sensitive that I would want to monitor on an emulated game anyways)! Use your wits if you have any, seriously.

Since, you lack the ability to conceive of a non-malicious purpose for monitoring chat packets; allow me to guide you to enlightenment.

I'm building a /tell based bot program to help those who want private servers and don't want to go through all the pains of macro managing multiple EQ Clients to form full groups.

But again, clearly you know my intentions better than my own. Go somewhere else to make nonsensical false allegations against people (a great place for that is in political forums since you were so ready to make a direct correlation between video gaming ethics and federal government policy) and spare us all.

Thanks


Anyways, does anyone have any intelligent thoughts on the matter now that my intentions have been made clear?

I'm not 100% sure, but I think this is what you're looking for:

common/EQPacket.cpp:

  390 void EQProtocolPacket::ChatDecode(unsigned char *buffer, int size, int DecodeKey)
  391 {
  392 	if (buffer[1]!=0x01 && buffer[0]!=0x02 && buffer[0]!=0x1d) {
  393 		int Key=DecodeKey;
  394 		unsigned char *test=(unsigned char *)malloc(size);
  395 		buffer+=2;
  396 		size-=2;
  397 
  398         	int i;
  399 		for (i = 0 ; i+4 <= size ; i+=4)
  400 		{
  401 			int pt = (*(int*)&buffer[i])^(Key);
  402 			Key = (*(int*)&buffer[i]);
  403 			*(int*)&test[i]=pt;
  404 		}
  405 		unsigned char KC=Key&0xFF;
  406 		for ( ; i < size ; i++)
  407 		{
  408 			test[i]=buffer[i]^KC;
  409 		}
  410 		memcpy(buffer,test,size);
  411 		free(test);
  412 	}
  413 }
