Hello.

I hope someone knows. 🙏 What does it mean that the R value starts with 0?
My other question is, what is the way to find the msb bits for lattice attack?

In elliptic curve digital signature algorithm (ECDSA), there are three (r,s,v) integers for every curve. The R [1...n-1] represents the x-coordinate on the elliptic curve based on a random point R on the curve which is created randomly thus results in starting with leading zero.
