It is protected with SSL/TLS. Here's a couple theories I had on how it could be done: http://projectpokemon.org/forums/showthread.php?780-GTS-website-research&p=82435&viewfull=1#post82435.

I was actually planning to start work on a client (doesn't require hacking like a server would) but there are no events up for download right now on any of the servers. Horrible luck considering there was one going on for B/W until two days ago. Guess I could still get the framework in place but it won't be ready until I can observe a full transaction.

I was talking about a program that acts like it was the Wi-Fi server distributing the wondercards or a distribution ROM to send them directly to the DS, but a program like that would be really good for getting pure, unmodified .pcd and .pgt files to add to the Event Collection thread. Again, I would love to try it out during development so it works in other countries, not just the U.S.

As we said, making a distribution server would be very difficult.

Poryhack is talking about making a client, which would be easier because you can extract the games' certificates from the ROMs.

But of course, it wouldn't be able to send WonderCards; only receive them.

Was there a link posted in Guested's post and then taken off for some reason?

I think we're all confuzzled now.

It would be great to have something like this to download things like the Enigma Stone and pokewalker paths and so on. I had a friend of mine lose her Pokemon Silver and I think that'd be the only solution that would be acceptable to her, to get the stuff back that she lost.

If you have a means to edit her save file you'd be better off going that route.

I didn't realize before that before I can make any progress on a client or server I need to see one unencrypted transaction. I have a few ideas on how to go about that but it'll be a much bigger task then I thought to write a client.

EDIT: Decided to elaborate for the aid of my own memory as well as the public record.

Option 1 is to cut straight to the chase and try to make a functioning server with the methods (most likely #2) described here. Obviously if we have a functioning server we can see what the DS is requesting and use that information to complete the server and additionally make a client.

Option 2 is to set up a SSL man in the middle (MITM) to view the plaintext traffic. I have my doubts about this one because the obvious choice of validation on the DS end is to check that the server's certificate is signed by Nintendo CA, in which case we're pretty much SOL because while we can spoof all the fields of a certificate to their normal value we can only sign it with our own private key. If for some stupid reason they're just doing field-checking it might work. - Confirmed that this won't work. 12/21

Option 3 is a guaranteed success but requires another whole skillset to pull off. In this scenario we directly modify a client ROM through assembly hacking to neuter the encryption functions, leaving the all-important outgoing messages open to our perusal. Alternatively we could try to eavesdrop on the messages in RAM before they're encrypted but this seems like significantly more work.

After much fiddling with openssl I've got some goodies.

This is a certificate and private key pair that can potentially be used in a MITM attack:

http://dl.dropbox.com/u/258536/fakepk.pem

And here's the real certificate for reference:

http://dl.dropbox.com/u/258536/realcert.cer

No real private key for obvious reasons, which limits the uses of the certificate.

the url is sent to the client as

svchost=ZGxzMS5uaW50ZW5kb3dpZmkubmV0

decoding the base64 encrypted string gives you

dls1.nintendowifi.net

it would be possible to hex edit it to use http but, as you said

I've tried connecting to it without SSL before and it will refuse the connection, sadly.

the server itself does not use http.

one possible solution would be to make a dns and a fake https server working like a proxy that redirects any data to the actual server as its logging actions.

Edit: At 0x0014e4c4 -0x0014e4d6 it says

https://%s/download

which is the url it requests.

also, some lines below i found the string

Now we're getting somewhere!

one possible solution would be to make a dns and a fake https server working like a proxy that redirects any data to the actual server as its logging actions.

As you can see from my earlier post I was considering an SSL MITM and at the same time kind of doubting it would work. You finding the request URL in plaintext changes things though. If GAMEFREAK's code doesn't break upon modifying that URL to use plain HTTP we could set up a proxy server to log whatever comes from the DS, SSL-ify it, and relay it to the real server then do the same thing in reverse for what the server sends back. Once we know the protocol we could use some of the same techniques to set up a fake server. The catch is that it would require ROM hacking; I may try to focus on methods that wouldn't require ROM hacking first.

Edit: At 0x0014e4c4 -0x0014e4d6 it says

https://%s/download

which is the url it requests.

Awesome find. I've searched all over for this but I never thought to look for just a partial URL. This'll be very useful; we could probably have a working client without anything more then this.

which might be the private key

...

I've seen these before and they are definitely SSL/certificate related. They're not the private key though; I'm not sure how much you know about RSA but the private key never needs to leave the server for the whole SSL scheme to work, having it on the DS would be pointless and even more insecure than GF normally is.

However, I am noticing good things that I failed to see before. The dls1 server's certificate correlates with "US, Washington, Nintendo of America Inc, NOA, Nintendo CA, ca@noa.nintendo.com" (those are several of the fields on the certificate). Each of the bytestrings you copied looks to be a public key (it's the correct length for a 1024bit key) and some metadata. The metadata actually precedes the "name" part.

Like this:

01 00 01 00 E0 CA 20 02 80 00 00 00 30 CB 20 02 03 00 00 00 C8 CA 20 02 // metadata

Good news. The CA public keys aren't encrypted.

Because Nintendo CA doesn't publish their public key I had no way to verify that it wasn't encrypted, but I think it's a safe bet because the public keys listed for the other CAs are not encrypted. I specifically checked the key under Thawte Consulting against the root certificate found here (Thawte is a subsidiary of Verisign) and it's a match.

What this means is that at the very least we can snoop on transactions with the genuine dls1 server and subsequently create and run fake server(s) that will work with an edited ROM as well as write a desktop client program that will work with any server. I still prefer a solution which wouldn't require an edited ROM (thus allowing retail card users to take advantage of it) which is why I'm going to try forcing the DS into a nonencrypted ciphersuite first. Beyond that the only way I can think of that would be viable for retail cards is to use RNG prediction which is not something I particularly want to try ...even if it worked out the process would have to be repeated for every connection to the server which would just be a nightmare.

Aren't there homebrews for flash carts that let you rip saves from commercial games? I've been searching through the forums trying to find what use event downloads on the main page are. I still haven't found out what I'm supposed to do with an even after I've downloaded it--there should really be some instructions for those somewhere (or some easy to find instructions). But I'm assuming it's some kind of save editing that's needed. If that's so, couldn't a save from a commercial game be ripped, edited, then restored to get the event(s)?

The goal of this project is to get wondercards onto retail game cards without 3rd party hardware and/or create a desktop client program to download wondercards from the official server.
