Sofar, i figured out that you can divide any pub keys with infinite numbers, and still get infinite valid results which goes back to the original pub key which results in infinite amount of collisions which results in an a big blackhole loop, that will never let you escape from it.

That's why I love Math. I saw some guy describing this as POINT_AT_INFINITY which i really agree with. Very well and nice describing

Here is what I found, I'm not a mathematician but this should work and it can bend elliptic curve or rather straighten it.

56900346571233247÷5 = 11380069314246649.4 + n/5 + n/4 = 11380069314246649, I just couldn't find any meaningful result before, but I have tried the above method and it works.

It seems we can just divide it after all, but this won't help much if private key is unknown, these things are like fire for a child when they see it for the first time.

I wanted to say a monkey when you perform a magic trick in front of him, have you seen how excited they get? Lol.

n works like zero in real numbers, n/x = n, n+x = x and so on.

Here is a problem I'm facing, it seems really easy to figure out, but I can't.
Because there is no solution. You can always divide by 5. In 20% cases, you will reach smaller key, in 80% some bigger one, just because every fifth number is divisible by 5. You can always divide by any number in range from 1 to n-1. Always.

You can clearly see that when trying to reach 1/2. In real numbers, it is some value between zero and one. But in ECDSA world, it could be for example 7fffffffffffffffffffffffffffffff5d576e7357a4501ddfe92f46681b20a1. You won't get any error, like "this division is impossible". It will never be rounded down to zero, or rounded up to one.

Division, exactly in the same way as multiplication, is always possible for all numbers from 1 to n-1. If you explore it on some smaller values, for example n=67 from my avatar, then you can clearly see that. You will rotate like in a clock, always getting "some" result, and never getting to the point of "no answer". And this is the beauty of the finite field, this is what makes it strong, and when you understand it, you will see, why you cannot "just divide it".

Theoretically, if we could find a big number that by dividing it to the public key resulting in an exact number, we could solve the private key from public key.

But that's way too hard i guess, it's like guessing a whole 254-255 bits..

obviously, if some private key is not divisible by 5, then you won't reach smaller key, you could get some bigger one as well. However, all ECDSA equations will be preserved in a given modulo.
Here is a problem I'm facing, it seems really easy to figure out, but I can't. Maybe you could give me a solution considering you are really good with math.

I have this key :
Code:
02228c3cbe2d11af48c3b98bc2955cd2c293375f748e9aea9040ffba42c3f6be1e
When I subtract it from this key :
Code:
0000000000000000000000000000000000000400000000000000000000000000
I get this result :  *first result
Code:
0352a1087d5f64b39c33d54e02f678c50955770b736e2c7c646d0ee04e28fc83e7

Now here is another key :
Code:
038840d5318a6369971b6610cbef8a7cb998d8e106534881da28aabfefeec2f41b

If we subtract the above from this one :
Code:
0000000000000000000000000000000000000080000000000000000000000000
We will reach this key :  which is 1/8 of *first result.
Code:
037f32d1fbba6ec4ed91109538ea93afc9bb4f13e3052d319263c7bb05fcb109a7

Do you think there is a way to find any of the public keys above?

I tried inversion and it doesn't work
It has to work. Let's test it on some key, where none of us knows the private key:
Code:
03 678AFDB0FE5548271967F1A67130B7105CD6A828E03909A67962E0EA1F61DEB6   Satoshi
02 2959350037EACA04CF26538AECA4402432BC2DEC271496446A326B22B7E08742   Satoshi/5=first
02 E8C7430A125F8FDA5B3AEA1C2C6CF7E404EE902B7150FE18CE397F2B4759AEC8   (Satoshi/5)*2
03 E1A4232B81AEA764680A74DC0F6CF58B26CB61048F0F70923DFD2F199B3C986C   ((Satoshi/5)*2)*2=second
03 678AFDB0FE5548271967F1A67130B7105CD6A828E03909A67962E0EA1F61DEB6   first+second
See? I splitted the public key from the Genesis Block into the sum of two public keys, where the second one is four times bigger than the first one. That means, I reached 1/5th of that key, because (1/5)+(4/5)=1. And you can easily validate that on your side, you need only point doubling, and point addition, nothing else.

if you divide +n odd key by 5 and then add n/5 to the result, you won't get near the 1/5 of your +n key.
Well, let's see that on some private keys:
Code:
SHA-256("garlonicon")=272fc6644fedff1a897d6034bed23f61859e99440ee699033307976590316723
272fc6644fedff1a897d6034bed23f61859e99440ee699033307976590316723   d
a16ff47a7662cc9ee84c4670f2f6d97924556ffe6c267ebe16e623cf335da22e   d/5=first
42dfe8f4ecc5993dd0988ce1e5edb2f38dfc031629045d406df9e9119685031b   (d/5)*2
85bfd1e9d98b327ba13119c3cbdb65e71bf8062c5208ba80dbf3d2232d0a0636   ((d/5)*2)*2=second
272fc6644fedff1a897d6034bed23f61859e99440ee699033307976590316723   first+second
See? It works. Of course, obviously, if some private key is not divisible by 5, then you won't reach smaller key, you could get some bigger one as well. However, all ECDSA equations will be preserved in a given modulo.

Just use inversion:
Code:
   n=fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141
 n/2=7fffffffffffffffffffffffffffffff5d576e7357a4501ddfe92f46681b20a1
-n/2=7fffffffffffffffffffffffffffffff5d576e7357a4501ddfe92f46681b20a0
 n/4=bfffffffffffffffffffffffffffffff0c0325ad0376782ccfddc6e99c28b0f1
 n/5=66666666666666666666666666666665e445f1f5dfb6a67e4cba8c385348e6e7
 n/6=d5555555555555555555555555555554463c62c03cbc85871fd9f975582d3661
I tried inversion and it doesn't work, if you divide +n odd key by 5 and then add n/5 to the result, you won't get near the 1/5 of your +n key.
I always use inversion and I'd never divide by anything other than n/2.

By the way, last time you messed up 1/2 with -1/2

I might have, but I don't recall, as I said I'm like a student learning here.😉

Thanks for nice answers everyone,

Yes, though I thought i was smart and decided to try to keep dividing public key by 2  to the lowest point reaching base point but I Failed Everytime haha.

I think the only way is to guess ODD VS EVEN but that's impossible since private keys are random numbers.  

I think it's like guessing 0 or 1 256 times, since there are 5 odd numbers and 5 even numbers in each new value. So the complexity stays the same as before.

Unless of course someone finds a way to know Odd private keys from EVEN, then he can divide by exact reaching his targeting key.

I like your examples guys!

The result is not random at all, did you even read my first post and other posts?
Random in, random out. Unknown in, unknown out. Infinity in, infinity out. It is that simple. If you divide some public key, where you don't know the private key, the result is totally random from your perspective. It may be non-random for the key owner, but not for the attacker.

I have tried 4, 5, 6 etc, I couldn't get any meaningful result, I'm still learning.
Just use inversion:
Code:
   n=fffffffffffffffffffffffffffffffebaaedce6af48a03bbfd25e8cd0364141
 n/2=7fffffffffffffffffffffffffffffff5d576e7357a4501ddfe92f46681b20a1
-n/2=7fffffffffffffffffffffffffffffff5d576e7357a4501ddfe92f46681b20a0
 n/4=bfffffffffffffffffffffffffffffff0c0325ad0376782ccfddc6e99c28b0f1

By the way, last time you messed up 1/2 with -1/2. This is a common mistake, been there, done that. If you learn more about inversion, you will know why. And if you want a proof, then halve a point using your method, and then double it. If you reach points, where 02 and 03 prefixes are inverted, you will understand, why you need inversion, instead of relying just on standard division, provided by any BigInteger implementation.

Furthermore, there are ways to accurately divide your key by 2 without any division, but that rock is really big and I'm afraid the glass will shatter
This problem is called "discrete logarithm", that's why you have DL letters in ECDLP. You can always divide a number by two, and finally reach the base point. The problem is: if you try to halve some point in a loop, you will visit a significant portion of the elliptic curve, I guess something above 2^250, maybe n/6 or something like that. So, don't run brute force on that, because you will never reach that answer in any reasonable time.

Does dividing a public key by a non division number really result in a random unknown point in the curve? Why is that though? For me, this makes no sense  : Huh Huh
The result is not random at all, did you even read my first post and other posts?

Let me give you a solution in order to successfully divide an odd key by 2, I have tried 4, 5, 6 etc, I couldn't get any meaningful result, I'm still learning.

Now the example, you could either add 1 or subtract 1 from your odd private (public key) key and then divide by 2 or you could simply divide the odd key by 2 add n/2 to the result, you will get the same result.

If your key is divisible  by 2, 4, 8 etc but the last digit is 1, you could reach key 0x3 by dividing by 2 adding n/2 and dividing the result again by 2 adding n/2 till you reach the lowest point.

Demonstration :

Private key :
Code:
0000000000000000000000000000000000000000000000000000000000008001
Public key :
Code:
03a3dd9bdf806a8c86fa43fd7c8af5fe3949b9244d46cfdf42aa716e3168f8e67b
Divided by 2, result:
Code:
024d2432b7f67a3b25fe7f6a52164f1bf0235d3f6ce00569f4fc954b823c7c7607
Adding n/2 to above
N/2 =
Code:
7fffffffffffffffffffffffffffffff5d576e7357a4501ddfe92f46681b20a0

Result, private key :
Code:
0000000000000000000000000000000000000000000000000000000000004001
Result, public key :
Code:
03d7ec238cd058837f44315fb8db2134f01daea15c10320c9173e7d5f68ff2d9d0

And if you keep dividing you will eventually reach 0x3, dividing 3 by 2 will give you 0x2 then 1, and dividing 1 by 2 will give you half, aka n/2 and take a look at 0.5 = n/2, it is a number around 2^255.

Now to simplify it, imagine you have 23 as your odd key, dividing by 2 adding n/2 will give you 12, it's like adding 1 to 23 = 24/2 = 12. You have 2 options.

Furthermore, there are ways to accurately divide your key by 2 without any division, but that rock is really big and I'm afraid the glass will shatter, you should start with small rocks, learn from Musk throwing a big rock at E-truck's window claiming it won't shatter. Lol

Yes, of course. For that reason, ECDSA is secure, and simple tricks like "let's divide it" won't work.

Quote
Why is that though?
Because we are in finite field. And the beauty of finite fields is that they are, well, finite.

Quote
For me, this makes no sense
It makes perfect sense, if you know, how things are calculated.

In real numbers, you have things like sqrt(8). In finite fields, you have for example 18.
Code:
18*18=324
324=79*4+8
324 modulo 79=8
See? In finite fields, you can have "18" as a result of "sqrt(8)", and it is perfectly valid, because "18*18" gives you "8" in this field.

@digaran i didn't understand anything you wrote here, but could you please help me at least compile the ecctools that Alberto wrote? I will be greatful

I believe there is a makefile for the ecctools at the top level of the repository.

Then again, it's been some time since I last checked it so it's possible that you compile the programs by running GCC directly. Each (?) of the programs are self-contained in a single file.

I guess I was speaking arabic right? 😅 that is math right there, follow up on it to get some where.


About compiling, I'm the worst person to ask, because I have the same problem as you, when I for example open visual studio  it's like an alien world to me. In case you didn't know, I used WP's ready to use for windows tools.

Nono, you werent speaking arabic. You just explain a lot of good things but the way you explain them, nobody but einstein could understand it.
Your examples are good, but as i said the way you explain things are catastrophic.

Thank you for nothing. We probably need help of Wandering around the jungle, i think he is the only and other few who can compile codes. I asked him but unfortunately he ignored me

@digaran i didn't understand anything you wrote here, but could you please help me at least compile the ecctools that Alberto wrote? I will be greatful

I want to do some mathematics, maybe i can get near to #130

So no, key division does not decrease search time.

Hmm, i dont know if i agree with this statement. When you create 1 million key with the help of subtracting the public key, You have like created a million clones of the targeted public key, and with that, you increase the chance. When you find 1 of the 1 million pubkey, you get back to the original key. So the chances is higher. And so is very similar to dividing.

And if you are dealing with prime numbers, look at N of secp256k1, if you just subtract 1 from it you can divide it by dozens of already known divisor numbers.

@digaran, you are fucking smart with coming up with this idea, but it still wont help us a lot finding the targeted priviate key.

Teach me more tips like that though!  Grin Grin
Took me 4 mins to correct the quotes you misplaced lol.

I'm the last person you'd want to teach you something, I just share what I know, they might be incorrect sometimes.

What you need to know about public keys, ignore their size and char length, it's all smoke and mirrors, they are simply representations of private keys, and private keys are simply ordinary numbers but very big ones.

Hexadecimal keys can make our work easier, for instance, if you have a large number like 3637343230303931363537383831353435
By the time you can figure out how to extract a certain number out of that, you'd be spending a few minutes, but if you convert to hex  you will get this
b355b9d94ef43E58a7f80fe3b85b

And in seconds I can select my target and then by guess work I'd take b as my first char assuming we know the first char is b, so I'd go with b000000000000E00000000000000  then I subtract from target to get
355b9d94ef43058a7f80fe3b85b
Then I go with this
bffffffffffffeffffffffffffff  subtracting target from it to reach
caa4626b10bc0a75807f01c47a4  and then I add the last result to this  +  355b9d94ef43058a7f80fe3b85b to reach =
ffffffffffff0ffffffffffffff
And just like that I now know the E I guessed is really there otherwise I'd see something else instead of 0 in the middle of fs  =  ffffffffffff0ffffffffffffff . 😉

Fun fact, 99% of times when I share something I know with others, I learn something new then and later on, this is why we need to share our knowledge, we gain more than we already have by sharing.
