Diffie-Hellman Key ExchangeLive

a shared secret over an open line

Alice

secret a = 6

sends A = g^a = 8

key = B^a = 2

Bob

secret b = 15

sends B = g^b = 19

key = A^b = 2

Eavesdropper sees g=5, p=23, A=8, B=19 — but cannot find the key 2

Bob's secret b

Diffie-Hellman lets two strangers agree on a secret key while an eavesdropper hears everything. Both share public numbers g and p, each picks a private exponent, and they exchange g raised to it. Raising the other's public value to your own secret yields the same shared key — yet recovering it from the public traffic requires solving the discrete logarithm, which is infeasible.

Governing equation

K = g^{ab} mod 23 = 2, A = g^{a} mod 23 = 8

Reading this result: Both sides arrive at the same key 2 because (g^a)^b and (g^b)^a are the same value mod 23 — yet an eavesdropper who sees g, p, A and B must still solve a discrete logarithm to recover it.

About this simulation

The full Diffie-Hellman tool models a zero-knowledge proof with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
