DSi Common Key Bruteforcer

WB3000 · Apr 17, 2009

It's nearly impossible, but the DSi Common Key could be bruteforced. Since this is a large community, it would increase the odds of finding it if as many as possible ran this program.

Updated: (5/5)
Download: http://www.mediafire.com/?zjmtdybjlum
+ Speed increase by roughly 16-20 times previous.
+ Fixed writing of common key to file.

Source and binary included (Windows, .NET only). It works by attempting to decrypt NUS DSi content.

Modes described (Bold is recommended mode):
- Standard: Increments from 0. Not recommended unless you are part of a BIG organized attack.
- 'Secure' Random: Generates random, non-zero byte keys to verify with. A good choice.
- '1' Bit Mode: Secure Random, but knows that the first bit of the key is 1, and makes sure the keys follow that rule.
- Standard Random: Obsolete due to uselessness.
- Debug Mode: Use to check certain key validity.

If you should happen to discover the key, be sure to inform someone who knows how to use it; ie. someone at DSiBrew/Wiibrew.

Good luck.

hm... I doubt it would be of any use if it would take years like you say, why not post on more sites

We can run multiple at once on one computer, true?

I don't see why not, although it wouldn't be wise on say a single core PC.

So will it tell me if it finds something?

Prints the key to the screen, yes.

Standard mode is not recommended, and will take years. Random mode could find the key at any moment, so it might not take years, might never find it.

So lets setup a bot net so a shit load of people can run it at once.

Any chance for some server program who gives a range to calculate. Since no doubt Nintendo will try to counter it, multitudes of the same range could be given. At least there is some more direction then imo.

Also: Will it save which ranges it has done when you quit? So it won't do the same ranges again when you restart again? Or is it completely random (secure random mode))?

The binary should be updated such that:

1) If the key is found, then it outputs the key to a new file in the same directory. It would really suck if someone happened to get the key and they accidentally closed the program.

2) Instead of outputting random keys tested, instead output number of keys attempted.

Well, you can call the program with key parameters for standard mode.

"program.exe AA BB CC DD EE FF 11 22" etc.

I'm not going to do much more work on this. It does what it does. You could in theory make something like that, and create batch scripts to take the key range.

Both are things I am considering.

There should be a web host that logs every key that has been tried so far, and relays these keys to the other users programs so that the key is not tested again.
Might be hard. i dont know
Would be better than setting up a server/botnet so people don't start hacking each other..

Forgot to add, thanks for cooking this up. I hope it'll come through with a key.

Why not have a server that can list all the keys that have already been tried, this can cutback the time by a ton seeing that the ones that already have been calculated wont be calculated gain. Narrowing it down all the time.

Sonicslasher · Apr 17, 2009

So what do I do with the hundreds of keys it puts up?

This wouldn't work with the random generator scheme, since you'd be checking the key you just generated against all the keys already generated by others (or yourself). It'd be a waste of time in that respect.

It might work if all the possible keys were chopped up into segments and a PC was delegated a range of values to check, incrementally asking the master list for a new range of values to check. However, this would require a dedicated server and a server / client interface. It'd also require a painstaking chopping-up of all possible keys, which would make for a HUGE list. It might not be feasible for us poor folk.

The keys shown every 1000 are just random. In a future build it will not show them, rather more stats regarding the process.

I guess that's where the botnet comes in.

Euhm, it doesn't have to record every key tried ... how about random ranges of 1.000.000 or 1.000.000.000 per "package" logged? I have no idea how many there are in total, but it shouldn't be that hard to divide them into packages for a range checked.
There seems to be 16 "FF" parts, even on my slow server computer thingy it's doing 1000 per sec ... so 65.535 (16 bit, right?) per min ... 16.777.215 (if I remember correctly) should be about 4.7hours. Seems to be a nice size for a "package". Or even a bigger range and save where it stopped...once done it would upload the result.

Or we could all just calculate randomly and do 40% (just a guess

) of the same calculations.

fgghjjkll · Apr 17, 2009

well...this is a windows application.
if you could make it support unix [cos it can like support multiple cpu's]
i could get my dad to get his friend who works at some hot shot tech company to crack it.

commdante · Apr 17, 2009

Wasn't the source-code posted too? Just run it through a compiler...

(It's rather addicting to check ones in a while...any prizes for it yet?

)
