Really nice finding, good job.

Also, I do know Nexon is using the following method to obtain the login auth token when logging in:

http://www.nexon.net/api/v001/account/login [userID=ragezone&password=ragezone]

EDIT: To easily get the values, I made a simple program in C# that gets them using RestSharp client.

Tagline and chat stuff are related to the Nexon Launcher.
http://games.nexon.net/nexonlauncher/

There are mentions of a chat system in NXL and there is a profile with a place for a tagline in it.

So what can this be used for? What applications can be created from this? I understand it gives account data, but that appears to be it.

This is just something "cool" to mess with. This is what Nexon's using to get data on their website / the auth token for the game. Nothing special.

I see, figured as much, shame it couldn't be put to use in an effective way.

Well, this can be useful if you want to get some data on an account easily by using it's ID and Password (e.x. checking an old account of yours for a certain amount of NX Cash before logging in into the game, checking an old account's email easily, etc...).

Why would they translate it? They are koreans (note: nexon.com)

that code gave me a seizure just from looking at it

write some nice clean groovy code instead

Since he's using C++ he probably wants to stick to native code, which means he'd be better off using Rust.

use std::io::net::tcp::TcpStream;
use std::io::{IoResult, BufferedWriter};
fn do_stuff() -> IoResult<String> {
    let username = "foo";
    let password = "bar";
    let nexon_host = "passport.nexoneu.com";
    let nexon_uri  = "/Service/Authentication.asmx/Login";
    let mut nexon_sock = try!(TcpStream::connect(nexon_host, 80));
    let mut nexon_writer = BufferedWriter::new(nexon_sock.clone());
    let body = format!(r#"{{"account":{{"userId":"{}","password":"{}","accessedGame":"MapleStory","captcha":"","isSaveID":true}}}}"#, username, password);
    try!(write!(nexon_writer, "POST {} HTTP/1.0\r\n", nexon_uri));
    try!(write!(nexon_writer, "User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)\r\n"));
    try!(write!(nexon_writer, "Content-Type: application/json\r\n"));
    try!(write!(nexon_writer, "Content-Length: {}\r\n", body.len()));
    try!(write!(nexon_writer, "Host: {}\r\n\r\n{}", nexon_host, body));
    try!(nexon_writer.flush());
    nexon_sock.read_to_string()
}
fn main() {
    println!("{}", do_stuff());
}

Unfortunately I seem to get the same request timeout error.
