4.0 out of 5 stars Introductory but not essential, 26 Jan. 2013
This review is from: Cryptography For Dummies (Kindle Edition)
This is more a book about how to use cryptography (especially in the workplace) rather than what cryptography actually is (no real technical details of the algorithms). I was hoping for the latter but settled for the former. It is successful in providing an introduction and broad overview that you would expect from such a title.

I think this book is probably suited for those that are required to understand encryption protocols and procedures in the workplace, and as a lay-person's reference guide. It is simple and written in plain English so don't expect anything advanced, the information here is correct but not up-to-date. I'd also say that all of this information is widely available on the web in several places, the positive point to reading this book would be that it contains all the relevant information in one place.

This book names and describes the (very) basics of encryption algorithms, where/ how/ why they are used, as well as related concepts such as digital certificates, digital fingerprints, hashes, checksums. It also list many products that were widely available on the market (when the book was first published) so you can potentially follow up reading this book by investigating what's on offer. Microsoft, Cisco and RSA still exist but whether the exact same products are on offer I couldn't say as I'm not an expert and perhaps an update for this book is over-due.

Perhaps the most important point to learn from this book is that the cryptographic algorithms are probably the strongest part of information transfer and the weakest link is the failure to use good procedures: for example, there is no point having the strongest encryption code possible if the passwords/keys are publicly available.
