1  Bitcoin / Development & Technical Discussion / Re: Pollard's kangaroo ECDLP solver on: December 11, 2023, 12:09:02 PM
Hi, i'm studying Kangaroo Software made by JeanLucPons and I'm trying to know if there is a possibility to compute more pubkeys during an attack.

Searching in the official git I've found that Jean said:

Yes,
I will add some note about this on the readme. It is a bit tricky.
Multi key support is not yet supported, for this you will need first to create a large tame array for a given range and then attack keys with it.

What does it mean? large tame array? Means maybe doing an one pubkey attack in a specific range complete that range using save.work and use it for other keys to attack? If I wanna do multi pubkey attack?

Thank you guys for replies.

Already exists ETC... Ethereum Classic can be in my opinion a re-ethereum pow based. (And only if the price goes up)

12 GPU's 3xxx series available, we have hashtopolis.

We are searching people we divide % we every verified member. We also check if wallet.dat are real..

Yeah .. He, most likely, generated 256 keys and manually updated the first character on the left whenever necessary.
You really think he just changed 1 digit? Some one who is an expert in cryptography would know better, but maybe he didn't want to make it very difficult and really used randomly generated keys. But if I were him, I'd have changed a few characters to make it really really hard, for example having a few 0s in a key will make it hard to reverse engineer a key manually, and brute force/kangaroo, well they have their limits.

One other thing could be placing a key outside a bit range, I'm curious did Satoshi ever confirmed that the keys are truly in the assumed bit ranges or we just hope the amounts of transactions are enough of a proof that the keys are exactly there?

But you know what I'd like to see? A large amount in a key with no exactly known bit range, somewhere between 160 and 180 bit not lower and not higher, then solving that key would be a global challenge, though not any amount which someone could spend half of it to use special tools and grab it, something which could only be solved by math and new methods.

For example, I haven't seen any tool/ algorithm capable of  adding or subtracting 1 to a key and then divide it by 2, kangaroo  engages square root calculations, BSGS looks for a match after adding/subtracting calculations, but no tool does + or - 1 then divide!

Now I look at it from a different angle. In binary, the program is more practical, for example, I know the last 8 bits of the private key anyway, because 8 bits equals a maximum of 256 digits. There was a friend who said that if the curve math is 0, multiply, if 1, add, knowing the last bit means solving ecdsa, the last 8 bits are 1 in 256, you can find the rest. If you say the last 16 bits, there is 1 possibility in 65536, these numbers can be tried, you will reduce 125 bits -16 bits =109bits.

This is the code

Code:

from sympy import mod_inverse
import secp256k1 as ice

k=mod_inverse(2,N)
neg1=ice.point_negation(ice.scalar_multiplication(1))

def ters(Qx,Scalar):
     ScalarBin = str(bin(Scalar))[2:]
     le=len(ScalarBin)
     for i in range (0,le):
        if ScalarBin[le-i] == "0":
            Qx=ice.point_multiplication(k,Qx)
        else:
            Qx=ice.point_addition(Qx,neg1)
            Qx=ice.point_multiplication(k,Qx)
     return ice.point_to_cpub(Qx)

for x in range(65536):
         print(ters(pub,x))


If the last bit is 1, it moves the point forward when divided by (2).

7fffffffffffffffffffffffffffffff5d576e7357a4501ddfe92f46681b20a1 +

if the last bit is 0 then normal divides

You trying to do mod_inverse using N. But N what is?

What are you trying to tell us?
What you wanna know?

Why have you published fake privs?

Ok next time i will publish real privatekey... why you all always take things so seriously? its just for fun And as far as I know, there are enough sensible people here who at least understand the difference between a joke and spam.


true, you are very good at joking, please do it more often haha ​​Wink

Hello,
is there any pool where we can combine all our gpus to bruteforce a puzzle?


hi yes we're working on a pool based with kangaroo write me on telegram @rickpwn

Dear @WanderingPhilospher please tell me what happened with stride in VanBitCracken, I have absolutely no idea how difficult this task is. But I hope that you will definitely be able to do it.
I have yet to figure it out. Therefore, I had to create my stride function with the help of python lol...python creates next stride; but this is not as fast as if it were built into the program.

program, python stride, program, python stride, etc.
is there a pool or group chat for 125? id love to toss my fire power with yours at this.

Hi, yes there is in development a pool for #125 puzzle. If you want to follow me, DM me.
i cant dm because im a newbie to this group you would have to pm me.

my telegram: @rickpwn

  And i have the domain name and hosting ready. Domain is 21 years old so it's solid. SSL certificate already setup
What domain do you own/have?

I had a pool running over 2 years ago, for #64. People say they will run their GPUs but we only had around 2-4 people running consistently.

What would be nice is to know everyone’s fire power, and then decide what tools to use, and best setup. But most get excited in the beginning and then fizzle out a week or so later when the key hasn’t been found lol.



I own cesr.net

Let's do it one more time. With that much money at stake, we should grow a huge community.

If do you have the idea of building a GPU pool, i'm here. I can join together with someone else.


DM so i can add you to the telegram group.




write me on telegram i'm @rickpwn
I cant DM to you cuz you dont accept newbie

Ciao ragazzi possiedo un vecchio wallet risalente al 2011... ma ho dimenticato la password per sbloccarlo. Ve la faccio breve. In sostanza sto cercando di crackare la password utilizzando strumenti avanzati di cracking mediante bruteforcing e wordlist. In mancata assenza di tanto hardware chiedo a voi se sareste interessati a unirvi a me e magari provare a sbloccarlo insieme per ricevere una parte del ricavo.
