Finding Mod-p Square Roots with the Tonelli-Shanks Algorithm

In this video we review the theory of quadratic residues of an odd prime and then implement the Tonelli-Shanks algorithm in Python to find a square root. We end the video by showing how we can use this algorithm to find points with given x-values on real world elliptic curves. Code: https://github.com/jacksoninfosec/ton...
