Title: Help please find a short (I apologise not more 26-64 byts) privatekey ? Post by: COBRAS on February 11, 2021, 06:48:42 PM I need find a privkey for this address:

This is a screen of my progress :'( https://ibb.co/Xs5kP8r This public key differs from the base point of the SECP256k1 curve quite a bit, so I assume that the private key is very small. This private key is a necessary intermediate step in my task. If I manage to solve the whole problem in the future(it requires 1-2 additional actions after finding this private key) then I will thank three people who responded and helped with a some amount in bitcoins. Please, those who will be engaged in the search write in this thread about the beginning of the search. Thx a lot. Title: Re: Help please find a short (I apologise not more 26-64 byts) privatekey ?

I'm sorry friends, It turns out that the potential range for the calculation is larger than I told you. So. IF SOMEONE FOUD PRIVKEY I WILL GIVE 1 BTC TO 3 PEPLE IF TASK WILL BE SUCCESS p.s. I think all no so bad First candidates for the rages with respect to X: 10000000000000000 6386c0450946b9c00000 try this range please ;) Title: Re: Help please find a short (I apologise not more 26-64 byts) privatekey ? Post by: WanderingPhilospher on February 11, 2021, 11:49:28 PM I took 3 minutes and ran through your new range with Kangaroo (went 2.1 over expected ops)...key is not there, or is but program needs to run a lot longer. I know you are merely guessing where the key may be located but your figures are slightly off...better luck next time

It's not. A curve point being only a short distance away from the base point is not an indicator that it was multiplied only a few times. Doubling G, and adding G to some multiple of G, completely moves away the x and y coordinates. This is the math behind doubling at least, which is done a few several dozen times for a given private key number. First, take lambda = (3Bx2 + a)/(2By) , where (Bx, By) are the coordinates of the point B you are trying to double, and a is a parameter whose value is given along with the type of curve you are using. Since you are using the secp256k1 curve, a = 0. So for the secp256k1 this expression becomes lambda = (3Bx2)/(2By) (I'm using red to color x coordinates and blue to color y coordinates). Next you compute Cx = lambda2 -2Bx, then you compute Cy = lambda*(Bx - Cx) - By . And this is how you get coordinates (Cx, Cy) of the point C = B*2. Point addition does a similar warping of the x and y coordinates. The very fact that you're multiplying the new points with a huge lambda implies that public key ranges do not correspond to private key ranges. |
