Diffie Hellman (Ch 4)¶
The Diffie Hellman algorithm is interesting in its own regards. The fact that an algorithm can allow two people to devise a secret that is unknown to a third person who is listening to everything they say is a clever bit of trickery. But it is also important in that it introduces some of the mathematical tricks that more advanced encryption algorithms also make use of.
These pages have resources for exploring the algorithm and figuring out how the math in it works.
