I'm still learning Keyhunt and I have another question...

https://github.com/albertobsd/keyhunt?tab=readme-ov-file#xpoint-mode

In that documentation for "xpoint mode" he says that you can add/subtract values from the public key of a puzzle to fill the search file with the public key itself plus a bunch more that are (what I'm going to call) small jumps away from the actual public key, in order to (if I'm understanding this all correctly) increase the changes of hitting a match...

The problem is that I can't figure out how to correctly do the addition/subtraction... Anyone know exactly how to do this?

His example is for puzzle #40... and I can take the (now known) private key, get the X/Y point from it, and make the correct public key from that... I then tried subtracting the number 453856235784 from the X value, the X & Y, and from the public key itself, but none of those attempts yielded the same result that he shows ("034eee474fe724cb631d19f24934e88016e4ef2aee80d086621d87d7f6066ff860")

Also, I assume the numbers chosen to add/subtract aren't important or special, correct? Like, they don't have to be multiples of 256 or anything, right...?

Any help would be much appreciated, thx

there are also more topics on this that you can find if you search for them.

Also in this topic you can a python script by Etar for public key division.
