Speed Up Discrete Logarithm Calculations with Pohlig–Hellman Algorithm 🔍

About this video

Suppose a ≡ bˣ mod m and we know a, b, m. Can you find x, and find it quickly? This is the "discrete log problem" and we meet the Pohlig–Hellman algorithm for solving this problem more quickly than merely applying brute force.
