WebMay 1, 2024 · For example: Bob and Alice agree on two numbers, a large prime, p = 29, and base g = 5; Now Bob picks a secret number, x (x = 4) and does the following: X = g^x % p (in this case % indicates the remainder. For example 3%2 is 3/2, where the remainder is 1). X = 5 ^4 % 29 = 625 % 29 = 16
