Section 6.5-6.7 and 7.1

It was interesting to read about real examples of the RSA system, and I understand that it is widely used still but reading about it is interesting.  It was cool to see that in some situations it is able to be broken, and that you could win all of $100 for doing so...  Also it was interesting to read about the different "trapdoors" that are built into public key systems, and they are necessary but also scary.  That's what all the allegations against the NSA are about right?

Discreet logs look like they are going to be almost as much fun as factoring large primes... Cryptography moves from one tricky thing to the next.  I guess thats the whole point of it thought isn't it.
