Well I somewhat understand how to configure tokenlist and am cracking at about 10,000 checks per second now on the GPU so I'm not sure why I'd need to switch to hashcat. I think I just need to refine my tokenlist now.
Ah, ok, good luck then! I think you have many hints, so your chances are really big! |

Exchange Reward Points for WoF Free Spins at FreeBitco.in and win Free BTC, Golden Tickets, Rolexes, iPhones, and more... every 24 hours! Does anyone ever won a watch? Again interesting time for betting on BTC price. Goes up and down, up and down. Today ranges looks very interesting, odds are really high (3.19 for 45-50, 4.33 for 42.5-45 and 5.67 for 40-42.5). Looks like time for bulls. |

-snip- I am wondering how to enable GPU?
Add --enable-gpu argument to your command. That's assuming that you've successfully installed pyopencl and your GPU is supported. b2352351, could you paste here the command you launch? In which mode you use btcrecover? Maybe in the one where GPU is not supported (or gives very limited performance improvement). What is "password"? Is it for a seed or brainwallet? |

so, question is your code working for without private key tell me
No, it is not possible, like others said before. I have one more remark: you take two random private keys, do a weird operation (“reverse”), calculate public keys from both and you expect to have correlation. It is a mistake from the beginning. You use hexadecimal representation, so you expect that key “abc” has something in common with key “cba”. The same key “12” in hex would be somehow correlated to key “21”. But on other hand, hex 12 is 18 in decimal system, which, if you reverse characters is 81, which is “51” in hex  do you see it makes no sense at all? If you represent private key in binary format, you will receive again completely different results. |

Forget about GPU for now, focus on correct configuration. We may help you build the token file, but you should tell clearly what do you know / what do you suspect. Do you know address for which you want to find private key? How the private key is build - is it kind of "brain wallet"? Or what you have is a password for custodial service/exchange? How the text is composed? From your first post I understand it could be: Uppercase letter
Uppercase or lowercase letter
Uppercase or lowercase letter
Uppercase or lowercase letter
1234567890 or symbols : !#$%&^*? etc...
1234567890 or symbols : !#$%&^*? etc...
1234567890 or symbols : !#$%&^*? etc...
Uppercase letter
Uppercase or lowercase letter
Uppercase or lowercase letter
Uppercase or lowercase letter
Right? just 11 characters or something extra in the middle, like dash (-) between sections? |

So, how can you build a firmware using a source code? How can you verify that it doesn't generate predictable entropy or that it's malicious in another way?
I am not sure if I understand you correctly, but in my opinion you ask 2 different questions: 1) technical problem - to build code you would probably need some documentation from the code authors, description how to do it, how to sign it, load into device etc. Trezor has a quite good documentation about that, they describe what you may do with a device with "non-original" firmware etc. 2) logical problem - here the problem is more complicated, because as I understand it requires the knowledge about all the touched aspects. Personally I think I would not be able to answer the question if entropy is predictable or not, if result is "good enough" etc. But on the other hand, I think it would be quite obvious or at least "visible" for someone with programming experience to find that there is a try to influent the result. Every part which has impact on seed, random number generation etc. could be suspected. And of course the other issue is if the whole code is written "in house" or if it depends on external libraries, which audit could be even more complicated. |

Here you are, a small program in java, uses bitcoinj library. I had 4 minutes to kill, so why not. BTW there are dozens of way how to reverse string, it is probably one of the most popular tasks for the 1st programming lesson  import org.bitcoinj.core.ECKey;
import java.math.BigInteger;
public class Reverse {
public static void main(String args[]){
//String originalKey = args[0];
String originalKey = "1234";
BigInteger originalBI = new BigInteger(originalKey, 16);
ECKey ecKey = ECKey.fromPrivate(originalBI);
System.out.println(originalBI.toString(16)+" -> "+ecKey.getPubKeyPoint().getXCoord().toString()+" "+ecKey.getPubKeyPoint().getYCoord().toString());
StringBuilder sb = new StringBuilder(originalKey);
sb.reverse();
BigInteger reversedBI = new BigInteger(sb.toString(), 16);
ecKey = ECKey.fromPrivate(reversedBI);
System.out.println(reversedBI.toString(16)+" -> "+ecKey.getPubKeyPoint().getXCoord().toString()+" "+ecKey.getPubKeyPoint().getYCoord().toString());
}
} Produced output: 1234 -> 37a4aef1f8423ca076e4b7d99a8cabff40ddb8231f2a9f01081f15d7fa65c1ba b96ced90a1b8f9b43a18fc900ff55af2be0e94b90a434fca5b9e226b835024cd

btcrecover in gpu mode works on Windows 10 without any problems, just follow the instruction how to install additional dependencies.
But let's move that aside. Are you sure you know how to read/understand the information you have?
Are you able to configure btcrecover to decrypt the data you have? I would first focus on proper configuration for your problem (to create a token file etc), not on GPU.
First try to launch in on CPU, maybe the performance will be good enough.

Every software developer knows that removing (unused) code makes software less vulnerable because it reduces the attack surface. That's a fact. Strange that some people defend extra features (extra code) even if they are not using them...
Even if i don't use that feature, someone else does and there's developer willing to implement and maintain it. But if no one willing to maintain it, i agree it's time to remove it gradually (starting from deprecation warning to actual removal after some time). Electrum's coverage is around 60%, which is not very bad ( https://coveralls.io/github/spesmilo/electrum?branch=master) I did not check exactly which lines are uncovered, but knowing developers and product's reliability we may assume all the critical parts are sufficiently tested. Everyone may use SonarQube to see quality of code and make their own opinion about it. I do not know if OP is mentioning features which are not (or rarely) used by end-users or pieces of coda which are not called/not used. It is true that code cleaning is always a good idea, but if there is code which is never used, I do not see why it could be dangerous (creating a new attack vector). It would be just annoying for developers. |

@slaman the guy who won this time had more than 4000 tickets
Ah yes, I have checked published table, but my sheet was sorted alphabetically, stupid me. So in fact yes, there were GT "whales" and today one of them won. Idea about pool is interesting, but requires users who trust each other but I think at the end it will be difficult to force someone to share the prize. |

I also have 1 Golden ticket from WoF. And there was fun bug related to it. When I checked few days ago how many golden tickets I have, they were showing 100% win chance with just 1 ticket. Unfortunately didn't made screenshoot. I already started to prepare place for Lambo in my garage. But now my chance to win become same like yours :/. I have seen "100% bug" in the daily email too, so I believe you. 93834 users had at least one ticket, with 2 users having max (989 tickets). 58155 single-ticket users. |

 only 7 and the win chance is very low, but the chance to win the lambo is still there. I am in the game too Just in the very last moment, daily WOF gave my GT:  and with 0.00008670% chance to win I will be waiting impatiently for the results  |

Mówisz o tym narzędziu co wysyła wiadomości na telegram, który podlinkowałem wyżej, czy o podobnej opcji wbudowanej w bitcointalk o której nie wiem? Jak ta pierwsza opcja, to pewnie szybko to zostanie poprawione. Sam autor jest online na forum prawie codziennie. Nawet dzisiał był online. BTW. Aż tak dużo ludzi ignorujesz ? Mi się jeszcze nie zdarzyło Nie, chodziło mi o zwykły email o nowej wiadomości w wątku. Chodziło o jedną osobę ;-) zdziwiło mnie tylko że niby ignorowana, a jednak triggeruje email z zawartością posta. |

It has been a really long time since I had won the high reward. Today I won 4100 Satoshis and I can't tell you how happy I am.
Now the question is how did you spend them ;-) I did not place any bet that week, I wait for next weekend for F1 GP and BTC price. I haven't spent the amount yet. I am still holding it in my freebitco.in account. I think I will either buy FUN tokens or use it for BTC/ETH price betting for this month. I don't think there's any better way to use these coins. What do you guys think 150 FUN tokens is not an amount which would change a lot I guess, so probably it is better to place a bet.\ |

Hi colleagues.
This is just for a CTF and I am not familiar with secp256k1 and hpw EC works.
I know 2 public keys (from Local and Server). I want to know how to obtain private keys for Local and server.
Can you please provide me any hint on how to do it?
What is Local, what is Server? In general, you ask for a very difficult subject. Knowing public key you may find corresponding private key only with huge cost of time and computational power. In other words - it is doable in reasonable time only for a limited number of private keys, in the range which is just a fraction of the full range used by Bitcoin / secp256k1 etc. We may say that there are some methods to solve the problem you ask for (like https://arxiv.org/pdf/1501.07019.pdf) and even there exists programs for that, but all that works only in some cases. Imagine that you look for someone, and to find him you must check manually every apartment, every house on the planet. Clearly you will not be able to find that person in reasonable time - but if it is just a test for your method and given person will be in the same building you start your search, or even on the same street, it confirms the method is mathematically correct. In other words - yes, it is possible that you find private key if you know public key only (it is not impossible), but the chance is so low that we say it is improbable. |

I think it is not too easy to do. And I think that in general you create your account because you already have link or you create the account just like that, without looking for side benefits. I have created my account without smy ref link - I honestly just didn’t think about it snd about possible benefits.
You need two accounts if you want to create an account with your own referral link. One of them will be main account and the second one would be referral of the main account. There is a risk involved in that case. Your account will be blocked as an abuser if their system catch the multiple accounts activity. Still a lot of people has done it, and some of them come here to complain when freebitco team block those users account. I have a feeling what you described is the easiest way to be banned ;-) That's not what I was talking about, I have my account with FUN tokens etc. and I am happy with that, too late to start everything from the beginning, just to have referral link. |
