Received your script! Give me a day to check it out and I'll get back to you. Appreciate it. By the way, if anyone wants my Nonce Recurrence Attack script, I’ve got it here. It uses a generator, not the enhanced…

Hey everyone, I'm trying to improve the Nonce Recurrence Attack. I checked out a paper on it, but I wanna take it a step further. I need to figure out how to make some fake signatures that still link to the same public…

Yeah, I could see that happening. If they ever drop S2 upgrade kits with the original specs, S4+ and S5 won’t sell at all.

No point in running this. The RSZ generated won’t link to the correct private or public key. I tried it ages ago and it didn’t work.

Just tweaked the gen_data.py script. Now it displays the K_Nonce value along with R, S, Z(HASH) Signatures right in the terminal. Not in the json file tho, guess that’s something to fix later. You have to put your…

Step 1: That’s a libelous claim. Step 2: There’s no magic involved. It’s just math; it’s not that complex. It’s been discussed here already. Check out this link, it's a good read but consider it carefully. Step 3:…

Hey all! Appreciate the messages and links you sent me. I found a solution to this method. One of you here suggested using SageMath's built-in function for the discrete logarithm problem. I tried it on real public keys…

So I figured out we can't just hit SECP256k1 straight on but we can create a twist on the curve by finding another Y coord on it. I checked this for the public key xy I'm working with. I had to identify the right curve…

I was warned about this just yesterday. Totally slipped my mind while coding. Thanks for the heads-up! Really appreciate it.

Just stumbled upon this research. The author managed to extract a private key by exploiting less than 4 bits of nonce leakage through multiple signatures. Crazy, right? I’m kinda stuck though. I have no k nonce, no…

I added this part: k = (r * i + z) * modinv(s, n) % n R = E.lift_x(Integer(r)) P = k * G print("K:", hex(P.xy()[0])) It worked! Found k but... ecdsa123 says nonce is 6, not the value I got.

Dude, try testing your code with this data. I ran your previous script and couldn’t find k! Test data: r = 115780575977492633039504758427830329241728645270042306223540962614150928364886 s =…

So I got this error: line 12 SyntaxError: Non-ASCII character in file nonce9.sage.py on line 12. No encoding declared; check the Python docs.

Just made some tweaks to my code. Would love some feedback on whether my approach is more efficient or even makes sense.
