[RELEASE] Yo-Gi-Oh! Online 3 Cryptography

They are using "Blowfish" in order to Encrypt/Decrypt their buffer.

here is the Blowfish code in C# , you would need "libeay32.dll"
Code:
public class Blowfish {
        private static readonly uint[] P = { 0x5EF6F472, 0x7D8186FD, 0x89922CDA, 0x29481716, 0x23C5A876, 0xD823BFAA, 0x40F87500, 0xECAA03CC, 0x97A3F6C8, 0xB2DA9755, 0x8DE04365, 0x33F5405B, 0xDFF19A4A, 0xAAD3F9A, 0xE2AE1496, 0xA81AA449, 0xB8FB4F9, 0x67223FE9 };

they are using "NetworkToHostOrder" to wirte/read their packets , you can use it or convert it to "HostToNetworkOrder" , if you are going to convert them as I did, here what you wanna do on Sending/Receiving:-

onSending():
Code:
public override void Send(byte[] buffer) {
            byte[] temp = new byte[buffer.Length + 4];
            int length = IPAddress.NetworkToHostOrder(buffer.Length);
            length ^= 0x77777777; // encrypt/decrypt length of the packet!
            Array.Copy(BitConverter.GetBytes(length), temp, 4);
            Array.Copy(buffer, 0, temp, 4, buffer.Length);
            bf.Encrypt(temp, 4, buffer.Length);
            base.Send(temp);
        }
onReceiving():
Code:
protected override void OnReceived(byte[] buffer) {   
	//get the correct length , TODO make a queue
	int len = IPAddress.HostToNetworkOrder(BitConverter.ToInt32(buffer, 0)) ^ 0x77777777;

	//you have to covert what ever you will read to NetworkToHostOrder, to be able to understand the packets!
	gameHandler.Handle(buffer,len);
}
that's it with sending/receiving packets!

sniffed packets:
in the attachment!

I really wanted to make a server , but I didn't have time , this codes could help someone making a base server, and with time and effort he could manage to make a full server.

oh man, this needs to happen. I have been waiting so long for a yugioh online 2 private server, if that can't happen, i hope at least duel accelerator is possible.

That's right... I decided to because everyone who shouldn't have it has already figured it out... and it's starting to spread quickly. There really isn't any reason to keep it secret anymore. Noobs that get hold of it can't code the patch anyways. Open where your Blowfish is... You'll see the "BF_set_key" and "BF_cfb64_encrypt" voids. Replace those with "CAST_set_key" and "CAST_cfb64_encrypt". The new key for it is "BC234xs45nme7HU9". Done.
