Query: Little more than a manual

This book gives a very poor guide to the context of SSL/TSL such that there is effectively no security guide to help orient the reader. Perhaps the author is not good at teaching. It reads rather like a manual, which is what it is IMO, except that it is not quite as formal. Perhaps the book could have redeemed itself if it were a little more engaging than a dead fish, perhaps a few red-herrings to keep us going. I was very disappointed. I expect books to be more than just manuals.All in all this book may be useful only to SSL implementors with an already excellent understanding of security/encryption. There is nothing else here, in my opinion. If you don't intend to write your own SSL implementation, or your understanding of encryption/security is weak, then don't buy this book.What was I looking for : I wanted to take the next step in understanding security/encryption after reading the original PGP security guide. In other words this is an outsiders perspective.
