Hello,
Just i want to ask one question,
Could be the blowfish key is more than 8 or 16 bytes like 21 bytes and if it is how can I save it in unprotected conquer.exe that only needs 16 bytes ?

You're talking about changing the encryption in the client? I believe there's a tutorial for that in the releases sub-forum.

16 byte
about changing the cryptkey of unprotected open conquer.exe with notepad search for TQserver
replace whatever at the right hand side with ur new key within 16 byte.

That's silly, way too easy to get the key then.

I guess, haha.

Well , thanks for answering me both
I will check sub-forum , but what i was asking for is how to add the encryption key if it is 21 bytes in unprotected conquer.exe i wanna make a cracked one not to protect a client

If the key is 21 bytes then only use the first 16 bytes of the key?

I have tried that but in vain.

You have to make sure the server only uses the first 16 bytes as well. There's no reason why a key should be strictly any length, including 21 bytes. Also, standard Blowfish key sizes are 32Bit and 64Bit, but up to 448Bit. Note that 1 Byte = 2 Bits, so a 32Bit key = 16 bytes. If you really wanted a secure crypto method, use something like Twofish or Rijndael at least.

Thanks , but i am sure that the BFkey is 21 bytes in the loader (42 bits )
and this is my problem , i can't add it to another unprotected loader as it doesn't carry more than 16 bytes (32 bits ).

Then change the length of the bytearray and generate a shorter key.

How ? =D

It's simple if you understand even a tiny bit of C#.. lol
