Diffie-Hellman Example Calculator

Example: Diffie - Hellman

Define Public Values:

n =

g =

Both Alice and Bob each pick a private x and compute a public X = g^x mod n

Alice	Bob
Alice chooses a Private Value a =	Bob chooses a Private Value b =

- or - - or -

Alice computes Public Value: A = g^a mod n (Public) A =	Bob computes Public Value: B = g^b mod n (Public) B =

Alice and Bob exchange Public Values
Alice and Bob each compute Same Master Value M

Alice computes M = B^a mod n = g^b^a mod n	Bob computes M = A^b mod n = g^a^b mod n
Alice computes M =	Bob computes M =
