Topic: Brute force private key tool? (Read 24340 times)

Mike, sorry to hear about your loss.

We have a service which is helping people recover lost crypto with Brute Force, Dictionary Attacks or through hypnosis (sorry, the last one was a joke)

For keys with no clue about the password, we do run a farm with "a couple of hundred" GPU's which is doing exactly this, scanning a couple of billion keys a second to see if we get a match with public addresses we have the approval from clients to do so. (From a few SATOSHI up to 10.000+ BTC's per address). We know the chance is very very small, but as an answer to above topic, YES, there IS a CHANCE.

If you would be interested to add your two public keys to our list and can confirm ownership, we would gladly have you as a client. We charge 20% if we do a match.

truth be told i have lost 2 keys many years ago, due to a RAID SSD failure which could not be rebuilt and even when i sent the drives to samsung for their review, the data was either missing or scrambled beyond use. I do not have those 2/3 drives anymore nor trust SSD based tech even today. i had established the raid due to a spindle failure back in 2011, and thought i had covered my ass when infact if it was spindle would of had a better chance.. the SSD just made things next to FML WTF ARGH ..etc etc.

I mean i remember some aspects about the keys but not the entire numbers.. i see people comment often on the odds of recovery and i sit here and wonder if they have ever lost their own keys, to where its a constant hinderance in their lives.. I lost 40-60million in current values 78xx btc over 2 accounts - granted i never assumed it would be worth this much but in 2013 it mattered never the less.

They were investment and business accounts so i had a partner also be invovled who reviewed it more than me as i was busy.. However i always assumed he made a physical back up as well, he didnt and its my own fault for not checking. So if there is anything even held in private i would love to recover my funds let alone  get the monkey off my back. its a constant thought daily almost.. which i really dont wish that upon anyone its horrid.

I was lucky to pull my money from mtgox before their mess and pulled from another platform as well prior to my loss... out of all the stuff that occured  its the dam raid which got me ... anyways when i read these and see the comments some of them are just snarky to say the least. As i said i bet most of these people didnt lose what amounts to a life change or many good things for alot of people; if i ever am able to recover my funds.. i can prove ownership well the best i can that is in 2013 .

JMO I think recovery is applicable from my own research over the years but im not a programmer and cant put it into practice.....  ps you can request quantum computer time from IBM if you have something you wish to research or run .. just be put on a wait list that inst really long at all..

Also i dont think the creator made this absoutely impossible to where legit people will lose their funds in a  event which is beyond their own control so in essence a back door or nitch needs to exisit.. (if it hasnt been removed by the programmers in recent years with the code revisions) whatever it is, its under lock and key and closely guarded i think.

well if anyone would like to assist or take a crack at it, i wouldnt mind and to me something even half is better than nothing at this point in the game let alone my life...
just wanted to share that i suppose..

anyways lesson learned the hardest way possible.. it has brought me to the conclusion that if there is a god it has to be a woman  *chuckle*
always wirte down your stuff.. or take a pic of it... *sigh*

It takes a lot of time that it looks really impossible. If you want to do it just for fun.. I think you won't get the fun that you expect.. 

Download this program:

and run it.  It does exactly that.  You can do billions or trillions of key pairs.  You will still not guess my key pair.  I am betting on that.

On a CPU, you can do 100 kkeys per second. That's many millions in a minute or in an hour.
On a GPU, you can do 30 mkeys per second. That's billions in a few hours.

Nothing prevents the key making and checking if any "click", but like you said, the odds are slim.

Slim = impossible, for all intents and purposes. Don't argue. You will sound like the guy that says "Soooo.. there is a chance?"

so  its *virtually* impossible to simply keep creating 30-character codes and checking to see if they are existing wallets with balances? I know the odds are slim, but what prevents making a million potential private keys, and checking them all to see if any "click"?

And this is an ideal point to link to The goddamn airplane on the goddamn treadmill

It will answer all your questions.

I hear this tool first time ever, what is the concept of these tool.

While we all sit around here arguing semantics, math, physics, etc.  Those of you that think it is possible can just do it.

You can download the program from here:  

https://bitcointalksearch.org/topic/2256-deep-space-vagabond-107172

The download link is back up!

Please report back here when you find your first few collisions and be sure and let us know how many BTC you are able to steal from the addresses you find!

Can't wait for your reports!

It's possible, but it's not possible in a human time frame.

You ruined the fun

This is fun to read because you are all arguing about, essentially, different things.

Some of you are arguing about semantics, in which possible fits the parameters of the mission.

Some of you are arguing about math, in which the probability approaches zero, such that the positive value above impossible cannot be expressed reasonably.

And still more of you are arguing about science, which I must say, is at least the most interesting of the arguments.

Keep going; I'll be back with a beer.

The "existence" of a possibility and the "likelihood" of a possibility are mutually exclusive properties. 

I'm going to claim that the possibility "exists" that my hands can dance around a keyboard and produce a 51 character, BASE 58, wallet import ready private key that's associated with an existing bitcoin address of my choosing.  5Kb8kLf9zgWQnogidDA76MzPL6TsZZY36hWXMssSzNydYXYB9KF

I'm also going to claim that the likelihood of such a possibility is so infinitesimally small that I will comfortably keep my bitcoin in a cold storage wallet and not lose a single wink of sleep.

This is the wrong argument, but I will use it anyway. I agree with Burt that brute forcing a randomly generated private key is impossible. As long as it has not happened yet, I stand by that statement.

Random means true or proper crypto random, not Android-broken-RNG random. (And it wasn't the key, it was the k or p or whatever value of the signature.)

Let me clarify that. Not able to occur, exist, or be done within the next one thousand years. For all practical purposes, truly impossible.

It's a lot easier to use a $5 wrench to extract the password from an unwilling interrogatee. Or to peek from above their should. Or to install malware on his computer. Or ... ... tell grandma that you're a computer repair technician and you got a call from the house to fix their unit.

og kush420:

I have already said exactly what I want to say:

If you do not understand what I am saying there or disagree with what I am saying then I no longer care.  Mostly because I am a cranky old fart who believes that if you cannot be bothered to press the damn shift key so that you can properly spell the first person singular pronoun then I (notice the spelling there) cannot be bothered to answer your posts.

As far as randomly selecting a private key that collides with another Bitcoin address goes your odds are better than you think.  There are only 2¹⁶⁰ possible Bitcoin addresses (not 2²⁵⁶) so smoke another bowl of kush 420 and give it a go, you might get lucky.

time travel to the past is impossible. to the future it is theoretically possible when you move fast enough.

please tell me what you define as 'impossible' as i agree that is likely where our confusion comes from.
we agree that a bruteforcer is not probable and almost certainly our universe would freeze/destroy itself before it could happen. however whether a private key can be cracked... yes it can. it can be typed into a computer by sheer 1/(2/\256) luck. i am not saying it will ever happen, not at all. but 1/2/\256 is a real number, is it not? you are essentially claiming it is not a real number or that when something passes a certain point of low odds, it is impossible. lets say there is a 49.999999999% that event X could occur before our universe destroys itself. do you say it is impossible event x could occur? because that is exactly what you claim with this example exact on a different scale.

impossible

    1.
    not able to occur, exist, or be done.

/\ notice it doesnt say 'extremely unlikely to occur'
do you say it is impossible that i can write a string of characters the length of a private key? do you say it is impossible that these characters could be a private key, even though we know it is possible just highly unlikely? do you say i cannot enter this string into a computer?

Totally agree, noobs should not use brainwallets. Gavin Andresen is firmly against brainwallets.

Here is an interesting post probing why brainwallets are a bad idea, the guy indeed made the scrypt.

Bitcoin is great but it's ease of use is poor and it's unforgiving nature... Well.. unforgiving.

Recommending Bitcoin to your grandmother would be a truly evil thing, the elderly are already prone to scammers even with the debt system babysitting them.
