Can someone please explain how to divide a point on the curve by 2?
I have been working on software for searching by public key, and I can divide by 2 by performing scalar multiplication by the inverse scalar, but this operation takes a long time. If anyone knows a faster way to divide, I can improve my code and release the tool for others to test.
There is no such a thing as division in EC math, there is only add, subtract and multiply, whatever you do, at the end you'll have to use * by inverse.
I wish there was a puzzle 161, so kalos could tackle it by finding rmd160 collisions, he seems to be interested in that.😅
