Layman's Guide to Elliptic-Curve Digital Signatures (2014)
Great guide but I run into a question almost immediately when it says "This line always intersects the elliptic curve at a 3rd point" and then subsequently "This line always intersects the elliptic curve at a 2nd point."Both of those statements seem false, since it's possible to pick points such that you get a vertical line near the left, like by putting the point on the X-axis (0 on the Y-Axis) in the second interactive example. Sure enough, doing so crashes the page.Is there just, like, limitations to where you can place the points? As in, you can place them anywhere so long as you're not creating a vertical line?
