"WebIn the first meaning, a "generator" is defined to be an element that generates the entire group. That is, when we talk about DH (and thus the group Z p ∗ ), we say that g generates the entire group means g k mod p can take on any value between 1 and p − 1. In the second meaning, we say that an element g "generates" a subgroup. " - Cryptographic generator
