6.1, due on October 5

The Interesting

- I am amazed that using the quadratic equation could yield p and q so easily. I don't think I would have ever thought to apply it in that way
- I loved the PGP method of encrypting emails. I never stopped to think about how the email messages were sent, I guess I just assumed they were sent in plaintext. Now that I think about it, though, this is such a cool and safe method and I'm glad that email companies do this. 

The Challenging

- I think I have a pretty basic understanding of RSA after reading this section, however, I had a hard time understanding how to figure out what d should be. It said to use the extended Euclidean algorithm, but with what?
- I don't particularly understand how to plug numbers into the different formulas on page 168 to get p and q because I'm having a hard time keeping all of the numbers straight.
