Web9 jun. 2024 · As all asymmetric algorithms go, ECDSA works in a way that’s easy to compute in one direction but mightily difficult to revert. In the case of ECDSA, a number on the curve is multiplied by another number and, therefore, produces a point on the curve. Figuring out the new point is challenging, even when you know the original point. WebAbout this update.
