Title: Huh?
Review: I was very suprised by this book. After reading some of the other reviews it seemed the author may have hit on a new idea or something midly profound. Unfortunately, no.This book is 13 chapters of Hashing functions and encryption functions. By hashing/or encrypting specific columns you can protect the data... Ok. No new concepts here. I could have read that in 3 paragraphs and saved myself an afternoon of reading and a few dollars.This book is *not* essential for DBA, developers or anyone else with a basic understanding of hashing or encryption functions.Perhaps this would be more appropriate in a college environment or for a beginer.
