WebNov 30, 2024 · For example, suppose we want to generate a public-key cryptography system for a user with the initials “ABC”. We might choose two large prime numbers, p p p and q q q, and then compute the product n = p q n = pq n = pq. The user’s public key would then be the pair (n, a) (n, a) (n, a), where aa is any integer not divisible by p p p or q q q.
