This asshole published my private key!

[Hohenn]

It is ''practically'' impossible for someone to bruteforce their way into getting your private key. There are way too many combinations for such a specific attack or even for one searching for a random wallet with coins in it. So yeah, your coins are safe unless someone gets direct access to that information through your pc.

Private keys exist as a series of alpha-numeric characters, and guess what? You could brute force your way in to someone's wallet, directory.io or not.

No, you cannot.

Technically, you can. It would just take 400 quadrillion years (give or take) to crack it.

Samr7 sums it up nicely here:

Can I use vanitygen to find someone else's private key from their bitcoin address?

Yes.  Vanitygen is a cryptographic brute-forcing application, and can be used to search for a complete address.  However, you will be unhappy with the amount of time required for it to find a match.

Good luck!

It will take years before anyone actually gets anything out of it finding each and every of those private keys.

[helloeverybody]

It will take years before anyone actually gets anything out of it finding each and every of those private keys.

I clicked through about 20 manually and then tried changing to random pages for example page 342142314124234341241234. guess what though, no dice. If you actually did have the computational power to bruteforce a private key then you would be better just using that power to mine or crack something else.

I realised that every few months some dude starts taking out this subject, it has been discused endless times, no no one has your private key.

ok so its been 400years and your family lineage has not even got passed the first 4 bytes of possibilities

but by this time everyone would have moved onto 2048bit encryption and your lineage would have to start again from 1, but this time with even less hope of getting them all in the next few eons

ok so its been 400years and your family lineage has not even got passed the first 4 bytes of possibilities

but by this time everyone would have moved onto 2048bit encryption and your lineage would have to start again from 1, but this time with even less hope of getting them all in the next few eons

Great demonstration that puts into context whats necessary to break Bitcoin. Cheers franky.

So there you go Rawdog. Really no need to run your mouth off at others, yet again. BTW, when did you remove the "1:1- Mastercoin/Bitcoin" nonsense in your sig?

[Jordan23]

You said Bitcoin was dead. Why do you care? Get some pussy (I see ur pic), if you can and cheer up.

[From Above]

Yeah man nice thread pointing out da beauty of cryptography and Bitcoin in particular.

It's some nifty tech, and pretty dope, don't ya think my nifty boyz

~CfA~

Crisis!!! Oh well, he can do what he wants but he is just wasting his time. Good luck for finding one collision.

That picture misleading, bitcoin has only 128 bit security not 256.

But even then performing intensive operations is not feasable for 2^128 operations + other operations.

So it is secure, but not as secure as the picture shows, see here:

It contains EVERYONES private keys.

Yes. BTW, Pi number also contains your private key, check it going from the end to the beginning.

[BillyBobZorton]

This is mental masturbation. No one has ever cracked any private key. OP is obviously trolling.

[MFahad]

It is ''practically'' impossible for someone to bruteforce their way into getting your private key. There are way too many combinations for such a specific attack or even for one searching for a random wallet with coins in it. So yeah, your coins are safe unless someone gets direct access to that information through your pc.

Private keys are not like passwords and bruteforce can only works on the password. The private key is safe unless you have written it on a piece of paper and that paper is stolen or lost.

Guys just see here my thread, it's minimum 128 bit security for your bitcoins, we already had experts telling this:

https://bitcointalk.org/index.php?topic=1523431.0


The minimum is 128 bit, and maximum is 160 bit , end of discussion.

So, it's only 80 bits of security against a quantum adversary, isn't it?

How did you calculated that? The minimum security a spent bitcoin address gives you is 128 bits, how did you get to 80 bits?

Hey, RawDog is the Master Troll and Bitcoin hater around here... He will do anything for a bit of attention. Just ignore the statement that everyone's private key is on that site, because it's impossible.

Just watch this little video and see for yourself ---> https://www.youtube.com/watch?v=ZloHVKk7DHk ... RawDog likes to confuse the newbies in the hope that they too would turn against Bitcoin for

some stupid reason.  

It is not impossible you fucking jackass.  It is totally possible.  Just because that guy limited his algorithm to a few prefixes from which an address can start, there is nothing at all to prevent someone from making an identical site which lists ALL bitcoin keys.  'impossbile' is a very big word dumbass.  Maybe you should stick to words with just two syllables so you'll be sure to understand the meaning of those.

Yea, and even if it was possible, you would have to take the rest of your sorry life to work through 1% of that to get a valid private key with some coins in it. Then you do not factor in the pass phrase

you have to solve on top of that. You are a damn fool, who has to resort to swearing and name calling to make your point. I have a good mind to add you to my ignore list, if it was not for the foolish

entertainment value of your posts. Sometimes I need to laugh at idiotic behaviour like yours, or I would end up like you.  

You are the fool my friend.  You don't need anything.  No passphrase.  Once you've got the private key - that is all you need.  I am surprised a guy with a big swinging dick that goes around explaining things to people would make such a mistake.  

How does it feel to be the idiot now, moron?  lolololol.  hahahahahaha.  You don't know what the fuck you are talking about.

I didn't say 'I'd work through it'.  That thought could only come to a moron, like you.  I merely said the guy published my key.  By the way, it take many more than a million lives to work through 1%, just in case you'd like to understand some facts.  

People as dumb as you shouldn't be posting.  Especially when calling others a fool.  Get a book moron, before you use a keyboard again.

Good you spotted it, I figured you would have missed that and I could school you.   .... You obviously studied the material before you started spreading fud and confusion and trolling a forum for

attention. I guess the most important victory for you would seem to you that you managed to place doubt in the minds of a few newbies that this would be possible, but the math is against you. This

whole thread serve as a educational tool for the newbies on how impossible this is... so it seems as though the troll thread has bounced back in your face, and it served the opposite purpose. If it was

mere trolling, it has served it's purpose and I have stepped into that again... lolololololo hahahahahahahah.

He who laughs last .......
