[BNCS] SID_AUTH_CHECK [0x51]

[pianka]

I think you could make the argument that knowing VB6 well does in fact make you a competent programmer.  As a programmer is someone who writes programs, knowing VB6 is a pretty easy way to accomplish that.  However, you could also make the argument that only knowing VB6 doesn't mean you're a competent developer;  where a developer is someone who can work as part of a team building robust applications and systems for real users.

Also, is competency judged simply by the frameworks, languages and paradigms you use?  Would a proficient assembly programmer be incompetent because they don't know how to use .NET?

[MyndFyre]

It doesn't matter, what platform you're on or what library you're using.  You can be a competent programmer in VB6, Java, C#, C++, C, Ada, Pascal, Python - the list goes on. 

However, it's a pretty commonplace perception that VB6 enables you to program without being competent, very easily.  It forgives you SO MUCH for pretty much anything that you do.

Now, that's not to say that you can't be incompetent and program in other languages.  It's just with VB6 being so widespread, it's gotten into the hands of a lot of stupid people, and their search to be able to get work done has ended up with them infecting the web with a lot of crappy code samples, that happen to function, but nobody knows why.

[MyndFyre]

An interesting quote I just read applies here:

A lot of programmers that you might interview these days are apt to consider recursion, pointers, and even data structures to be a silly implementation detail which has been abstracted away by today's many happy programming languages. "When was the last time you had to write a sorting algorithm?" they snicker.

Still, I don't really care. I want my ER doctor to understand anatomy, even if all she has to do is put the computerized defibrillator nodes on my chest and push the big red button, and I want programmers to know programming down to the CPU level, even if Ruby on Rails does read your mind and build a complete Web 2.0 social collaborative networking site for you with three clicks of the mouse.

Hello

I have questions again...

What to specify in the field cd-key in SID_AUTH_CHECK packet if I play a piracy server and I have no cd-key?

I wrote:
   

Code Select Expand

packet = new BNetPacket(PacketIDs.SID_AUTH_CHECK);
packet.addDWord(clientToken);
packet.addDWord(results.getVerhash());
packet.addDWord(results.getChecksum());
packet.addDWord(0);
packet.addDWord(results.getChecksum());
packet.addString("");
logger.info("\n" + packet);
out.write(packet.getBytes());
out.flush();


How correctly to specify the password in SID_LOGONRESPONSE2?

I wrote:

Code Select Expand

packet = new BNetPacket(PacketIDs.SID_LOGONRESPONSE2);
packet.addDWord(clientToken);
packet.addDWord(serverToken);
int[] myPass = DoubleHash.doubleHash(password, clientToken, serverToken);
for (int i = 0; i < 5; i++)
    packet.addDWord(myPass[i]);
packet.addNTString(name);
logger.info("\n" + packet);
out.write(packet.getBytes());
out.flush();

Please help!

[rabbit]

First: any password that passes install checks will work on 3rd part servers.

Second:

Code Select Expand

packet.addDWord(results.getChecksum());
packet.addDWord(0);
packet.addDWord(results.getChecksum()); Why are you inserting results.getChecksum() twice?

Third: I don't know what library you're using for your hashing, but it looks fine?

I do not understand, it is possible more in detail?

I'm use this classes for hashing :

Hurrah!!!! I have come into a chat

[Hdx]

1) Dear gone someone butchered JBLS more than Joe/I did!
2) Your password must be double hashes jsut like normal for fake servers as well as real ones
3) For CDKey, you need to send it a valid cdkey IIRC 3333333333333 works.

He said it's a hacked version of a hacked version of JBLS, and it sucks.

To elaborate, it has to decode. It doesn't have to be accepted by [the real] Battle.net, or probably even have the right product ID.
