Bitcoin Forum

Hello.

First for all this was only for fun. When i finished that i only used it 2 days for merely fun.
But, i spent so many days to develop that. I would explain:

Previous requirements:
-Ubuntu linux with Abe (Bitcoin open source database) full filled, mysql table address with all know public addresses. Migrate it to an SSD to fast performance.
-.Net framework 4.5 (or 2, 3.5, 4 if you get the code and wants to compile it).
-Oclvanitygen.
-Optional - AMD GPU +5xxx  for an acceptable performance at Oclvanitygen and x64 cpu for Oclvanitygen64

I mixed Abe and results of the Oclvanitygen in two types of "attack", absurds "attacks" for fun.

1) Try to generate with Oclvanitygen a priv key of the most rich address (extracted of Abe and stored in memory for fast performance) @20M/s with adjustable prefixes (4-8 chars, dont remember but the range is 1000checks/s for 4 chars and 1 check/minute for 8chars whit the 10 most rich addresses). If this find one, store it in mysql table automatically.

2) Try to pass max allowed number of prefixes of know addresses to Oclvanitygen and check te results in the full table of addresses.

3) Idea for future develop (i dont have motivation for this, is boring me): Dictionary attacks mixed whit Abe (a forum member try this time ago).


cheers and nice rally!

So you wrote a useless (and I agree trying to brute force 256 bit random keys is utterly useless) program for fun and want $300 to $600 for it.

Well you have confidence I give you that.

Yes.
And addition the code is not comented and dirty.

Thanks for the clarification you sold me.  The check is in the mail.

My first intention is not sell the code, is most share with bitcointalk my little "botched job" (Sorry for my english). Secondary if some wants to get the code for research and recicle it, have to donate some to me.

Casascius has the same software in C#, to calculate everything, with 5 minutes of work you could have it loop to find any given key. Why would someone not pay $20 to have his code modified and accomplish the same, impossible feat?

To save more of 100 hours of work. Not easy as you say, not only a loop.

The program execute oclvanity and process the results at runtime automaticaly, and is integrated with Abe database.

You took 100 hours, that is ok. But that doesn't mean someone that knows what he is doing will take more than 15 minutes.

If so, I challenge any programmer to get it (exactly the same processes. Oclvanity+Abe runtime comparisons) in less than two days, offer 0.2 BTCs.

AHAHAHAHHAHAHAHAHHAHAHAHAHAHA

you already had me at C#

 ;D

(Sql, Java and .Net)

And Sockets, don't forget Sockets!

Not really. 90% from this list is must-to-know for anyone who writes programs for business.

congratulations, you can compile a list of buzzwords.

Sockets are complex  ;D


Really? In five minutes?
Is a copy&paste of my linkedin

Thanks, but i already have a great job.

Please don't off-topic.

Can you show us some of your work? Or a github account, perhaps?

also:

>Microsoft Excel

That list was absolutely the biggest laugh i've had in a long time... It looks like a 16 year old collected a list of all the things he sort of came in contact with.

You have better chances of winning the lotto than break open an address in 10 years

Why would should do? (My works are not public, work for goverment administration intranet systems, healthcare systems...)



Correct.

How about a curriculum vitae then?

Also, if you agree on the fact that it's nearly impossible to get a private key, how do you expect people to buy this?

If you have a chance (now or in the future) to reach x1000 of the hash rate of one radeon 5xxx (20Mh/s) with oclvanitygen you will increase chances of get a collision and store it with the application.

Which still makes it absolutely useless.

You mean: If you converted the entire energy output of the sun to key-cracking in the most efficient way possible, you'd have a chance that's virtually indistinguishable from zero to find a private key for a given address if you run the program until the sun dies in 5B year.

Seriously: Check the numbers, this type of attack doesn't even come close to being feasible and you're asking people to pay for it?

Don't mess with him, dude! He's very experienced with Alfresco and Struts.
He's can SQL your socket in NO TIME.
I messed with a Java Nivel alto guy once... Biggest mistake ever. He Microsoft Excelled my Oracle.
He's an "31337 |-|4><0|9"

Ok, edited it at first post, dont have any interest on sell it...
