I also used "make" command for KeyHunt and it compiled and worked perfectly.

OK, i see that, please edit the gmpecc.h file and add the next line at the begging of the file

Code:

#pragma once

And try to recompile it again

More info here: https://docs.microsoft.com/en-us/cpp/preprocessor/once?view=msvc-160

if that works please let me know for make that change too in the next update

This did not work...I will work on it more later today. Thanks for responding!

Yes you are totally right, my logic in the first version was was the next:

if the target publickey was at the middle of the range, the subtracted keys will land from the beginning of the bit range up to the end of the same bit range.
if the target publickey was at the begging of the range, the subtracted keys will land in the first half of the bit range and the other half will land in the previous bit range
but if the target publickey was at the end of the range, the subtracted keys will land in the last half of the bit range and the other half will land in the next bit range
Obviously those are perfect cases, but the reality is that we don't know where is the target publickey, so my orignal idea was just increase the probability to have near a subtracted key in anywhere in the selected keyspace

But I repeat you are right i will add the option of select only make a subtract or addition.

Also think in the next one:

if you are working with targets in the 256 bit space, any addition may end in a lower bit space due to cyclical behavior of the eliptic curve

I think it is good the way it is. Your logic is different that mine but your program works just fine for the way some would use it. Like I said, I can generate millions of offset keys with -b 100 and all of those offset keys will be in the original 119 keyspace for pubkey #120. You can also pre-subtract pubkey down to a specific range and then use keysubtracter, which is what I do. So I have millions of pubkeys in a 116 bit range, but only 1/8th of those new offset keys will be within that range.

I do like the option of selecting just subtract or addition, but not 100% necessary. A great, fast program that I have been looking for, for a long time. Many thanks!

Yes i see that error before, is some re-declaration of that G variable (gmpecc.c load the gmpecc.h but also keysubtracter is loading that header file, i manage avoid that with the Makefile), maybe adding some header directive like #prama once can be useful , but i don't know if it can work for you.

Are you using the command "make" in Mingw64 ?

If not, can you add the command that you are using to compile it?

Yes, I am using the "make" command in Mingw64.

I also used "make" command for KeyHunt and it compiled and worked perfectly.

If you see the number after the # char, is that the number that is being substracted or added to the original given publickey.

I am not sure if I understand the reason to add and compare.

It makes total sense to subtract from the 120bit key and compare it with a smaller range.

I know you mainly build for Linux but wasn't sure if this was something you have seen/experienced before.

You can use this program in many ways. But if you generate millions of offset keys say with a -b 100 flag, then all of those keys, whether added or subtracted, will still all be within the 8000... through ffff.... range that the 120 key lies in. In this way, you have created millions of keys to search in the original range. You can use this program to reduce/subtract down to a given range and extract just the subtracted keys, but you will have many keys generated that do not lie in your reduced range.

Github page: https://github.com/albertobsd/keysubtracter

I publish this code on github in April 5, but i never update it until now, this is a small tool to make some substracted publickeys, address or hashes rmd160 from a target publickey.

This can be useful to increment our chances of hit some privatekey of the puzzles.

For example to make 100 copies of the puzzle 120 you need to execute the next command:

Code:

./keysubtracter -p 02ceb6cbbcdbdf5ef7150682150f4ce2c6f4807b349827dcdbdd1f2efa885a2630 -n 100 -b 120

Output

How many bits does it subtract it by?

It will subtract by however many bits you tell it to.
In his example:

Code:

./keysubtracter -p 02ceb6cbbcdbdf5ef7150682150f4ce2c6f4807b349827dcdbdd1f2efa885a2630 -n 100 -b 120

He is telling the program to add and subtract up to 120 bits. You could change -b 120 to whatever; -b 50, -b 74, and that would be 50 and 74 bits. You can spread the bits out over a range as well using the -n 2048 -r 0:fffffffffff option as well. That will generate 2048 keys spread out evenly over the range of 0 through fffffffffff

I have built the KeyHunt for Windows using Mingw64 -make, but I receive this error when trying to use the make for keysubtracter:

Hello Alberto,

Can you make the mapping from the list by converting all extracted keys to HASH160?

I think it would be more effective than Pub2RMD feature.

Edit : I just checked. You made an update today, exactly what I wanted. Thank you very much.
