Starcraft Keys

[Tazo]

which makes a pattern finding program nonexistant, or impossible to make. If it did exist, I'm sure that everyone would have 5000 keys or whatever..

[Arta]

Extremely difficult. Not impossible. A discernable pattern may exist.

Let's see who else noticed that his 998-999 all begin with even numbers, and the rest begin with odd and even. That the 11th digit is always the second number in the private value. Also take notice on some of the private values on the odd number keys, you will notice something changes with the 11th digit in some of the keys. This DOES NOT happen with real Even working Keys. This only happens with odd keys. I have not noticed a difference in working and non odd keys.

When SCKMG generated all valid (by installer check) CD-Keys, the resulting file was about 4GB.

After further testing I have noticed something with all private values of 998, not only do all keys with a private value of 998 begin with even numbers, the 10th digit is always 1. I have tested this with 200 working bnet keys with a private value of 998, and every key has had the 1. I have not found any other key with something other than a 1 to work.

Note: The public value must be within a certain range. Any public value outside this range will be invalid.

10th digit of 2826835493962 isn't 1.

[LordNevar]

Didn't say it was improbable that it couldn't be something other than a 1, I just happened to notice that the 10th digit on the one's I had were 1. Although yours is a 3, it would be interesting to know if you have any with an even number there instead of an odd with the same public and private range.

On the subject of 'odd and even' numbers, maybe all valid ones have an odd number for the 10th digit?  I haven't tested this, i'm only suggesting.. Anybody care to test this?

Why are you looking at the digits of the encoded key?

[QwertyMonster]

Umm, i didn't say i was. I was just commenting on UserLoser's and LordNevar's post..

I got bored. Hopefully this helps someone. Merry Christmas!

Just so you know, there are also valid keys with product value of 2.
http://forum.valhallalegends.com/index.php?topic=13318.msg135710#msg135710

EDIT: Also I notice you're not even decoding the key. You have to actually decode the key to get the first 2 places of the key to determine the product value. Or is there something I'm missing?

Yeah, I didn't realize that until after I wrote that. =p

I have a program under development that is about 65% done, it is in C++ http://www.grimhosting.com/grim`mass - Check it out. I'm going to put the list of 1.39GB of keys I have (after using the check the installer uses and running 0000000000000-9999999999999 through it) and let it just run, it auto-refreshes proxies and i'm going to have a scanner running 24/7 outputting the the bot's proxie file. I'll post the results here.

On a Linux box, that 1.39GB list can be created by using the command "sckmg > /home/joe/keys.txt", after downloading and building sckmg.
