PassKey.Me: Securing Your Digital Identity (available at Amazon.com)
This book is decidedly distrustful of computers to transmit messages; for encryption methods are hidden within proprietary black boxes. These boxes, otherwise known as applications, are within operating systems. Both the boxes and the systems can be hacked.
In contrast, this book uses a simple calculator, a pencil and paper to encrypt messages. Advanced security professionals when attending conferences often do not communicate digitally. And so as these professional are suspicious so too everyday users should also be distrustful.
Although the book is addressed to professionals, it is written in everyday language of non-specialist Users. Much of what is written about security is written within the impenetrable jargon of computerese. I wish to distribute that knowledge more broadly. But make no mistake: although this book uses simplistic tools and language, its encryption is a dependable, but not faultless tool preventing Hackers from cracking messages.
The first part of the book deals with the creation of Credentials, known as a PassKey.Me. which are in fact encryption keys. The book focuses remembered three encryption keys using memory systems. The systems can range from very simple to complex systems depending on the needs of the User. Gladly, I can report that there is no need for a digital password keeper.
The second part of the book deals with encryption of messages. A code book is presented so that a number is matched to a set of letters. Typically, codebooks are almost never published, but held in secrecy allowing the sender and recipient to communicate in privacy. This book, however, presents methods of encryption of the code numbers using simple mathematical calculations that can be preformed with hand held tools. As a proof of concept, a cryptogram is published within the book and online in order to challenge readers to decode the message.
