def check_pohlig_hellman(curve, generator=None):
"""
The Pohlig-Hellman algorithm allows for quick (EC)DLP solving if the order of the curve is smooth,
i.e its order is a product of multiple (small) primes.
The best general purpose algorithm for finding a discrete logarithm is the Baby-step giant-step
algorithm, with a running time of O(sqrt(n)).
If the order of the curve (over a finite field) is smooth, we can however solve the (EC)DLP
algorithm by solving the (EC)DLP for all the prime powers that make up the order, then using the
