content: This book starts slowly but gets better and better as it goes along. Very complicated subjects are presented clearly. I finally know what the RSA conferences are about here in Silicon Valley (and I finally know what RSA means). The RSA algorithm is neat and I am determined to hack it (fat chance). Gotta be a way...And now I understand great uses for the modulus. Yep, this was a book that held my attention all the way and I am definitely not a math freak.Only nit was when the author used "prizes" instead of "pries".I highly recommend this book!
