== The general algorithm ==
In this section, we presentpresentaddd the general case of the Pohlig-Hellman algorithm. The core ingredients are the algorithm from the previous section (to compute a logarithm modulo each prime power in the group order) and the [[Chinese remainder theorem]] (to combine these to a logarithm in the full group).
 
(Again, we assume the group to be cyclic, with the understanding that a non-cyclic group must be replaced by the subgroup generated by the logarithm's base element.)
