Ummmm, how to use the key for lv.dat? Does level.dat have the same de/encrytion routine as itemtype.dat

If possible teach me the process of decrypting itemtype.dat. Eg, finding keys and de/encrytion process

chocoman's source?

Just replace the byte arrays. Yes

Also are you 32 bit or 64 bit?

Im at 32 bit. I dont know why isn't working This is the first application which doesn't work on my computer... :|

In coder62's itemtype DeEn thread, first page, Chocoman4k released his version of the de/en routine in C++. That was the one i made use of.

example: 

CounterA = 7
CounterB = CounterA Mod 128 //=0x7
CounterC = CounterA Mod 8 //=0x7
ByteA = 0xBB
ByteB = 0x09
xor ByteA, ByteB // 0xBB xor 0x0E = 0xB2
ByteC = ByteA  // =0xB2
shl ByteA, (8 - CounterC) // ByteA = 0x64
shr ByteC, CounterC //ByteC = 0x1
result = ByteA + ByteC // 0x64 + 0x1 = 0x65 (101 = "e")

i don't quite get what does 0x7 mean. I fact, what is the exact meaning of "0x" does it convert from hex to dec or what?

Well, you can use the tool i made.

Extract the pure_itemtypeEnDe.exe into your ..Conquer2.0/ini folder and run.
The menu is easy to understand, just follow instructions.

Hi guys, i tryed to include the encrypt and decrypt functions into my own project, which should check automatically, if the itemtype.dat was updated by conquer and then decrypt, replace some strings in it and write back encrypted into itemtype.dat.

Here is my code:

}
}
}

Everytime i try to run it, it says "overflow" and i found out it stops at the function decrypt at bytes[i] = (byte)((t1 << (0x8 - t2)) + (t1 >> t2));
I worked the original programm through and the variables at the first time are have the same worth like they are in my program, but in my program is an overflow. I hope you can help me.

Mfg Sissi.

What is "i"'s value on overflow? And how big is the array?

[Hiyoal]

How do you find the initial key in the first place?? What are the steps to go through. Could you please enlighten me on this Topic High...This one time.

Hiyoal

[Sissi]

i is the counter from 0 to end of the array and the array is the whole file, like in your code. Strange is in your prog, when i compile, it works, but not at mine. But it seems that my software (sharpdevelop) is the problem - its freeware and if others do the same with my code it works.
Seems i need to borrow me that software fom them, thx anywhere

[Dgen]

Why doesn't this program work for me? It shows and error when i want to start it.



EDiT: I fixed it .

[Guerilla]

Thank you very much.

[torbido]

good ty

[Hassan28]

nice ty

[elragal_30]

alot thanks i was search for it while ago
thanks for @nTL3fTy for guide me
and can i use this code for all dat files?? or just co ??

Just encrypted CO2 ones, because there are some CO2 .dat files that are not encrypted (such as MagicType (as of v5017)).

[Deriaz]

Thanks alot for this, it both helped me getting monsters smaller and learned me how to encrypt/decrypt easily, thanks a lot!
