Simple Steps to Data Encryption: A Practical Guide to Secure Computing: summary, description and annotation
We offer to read an annotation, description, summary or preface (depends on what the author of the book "Simple Steps to Data Encryption: A Practical Guide to Secure Computing" wrote himself). If you haven't found the necessary information about the book — write in the comments, we will try to find it.
Everyone wants privacy and security online, something that most computer users have more or less given up on as far as their personal data is concerned. There is no shortage of good encryption software, and no shortage of books, articles and essays that purport to be about how to use it. Yet there is precious little for ordinary users who want just enough information about encryption to use it safely and securely and appropriately--WITHOUT having to become experts in cryptography.
Data encryption is a powerful tool, if used properly. Encryption turns ordinary, readable data into what looks like gibberish, but gibberish that only the end user can turn back into readable data again. The difficulty of encryption has much to do with deciding what kinds of threats one needs to protect against and then using the proper tool in the correct way. Its kind of like a manual transmission in a car: learning to drive with one is easy; learning to build one is hard.
The goal of this title is to present just enough for an average reader to begin protecting his or her data, immediately. Books and articles currently available about encryption start out with statistics and reports on the costs of data loss, and quickly get bogged down in cryptographic theory and jargon followed by attempts to comprehensively list all the latest and greatest tools and techniques. After step-by-step walkthroughs of the download and install process, theres precious little room left for what most readers really want: how to encrypt a thumb drive or email message, or digitally sign a data file.
There are terabytes of content that explain how cryptography works, why its important, and all the different pieces of software that can be used to do it; there is precious little content available that couples concrete threats to data with explicit responses to those threats. This title fills that niche.
By reading this title readers will be provided with a step by step hands-on guide that includes:
- Simple descriptions of actual threat scenarios
- Simple, step-by-step instructions for securing data
- How to use open source, time-proven and peer-reviewed cryptographic software
- Easy to follow tips for safer computing
- Unbiased and platform-independent coverage of encryption tools and techniques
- Simple descriptions of actual threat scenarios
- Simple, step-by-step instructions for securing data
- How to use open source, time-proven and peer-reviewed cryptographic software

. GnuPG works at the command line, so OS X and Linux users open a terminal window, Windows users open the command line window.
To encrypt a file ( example.doc ) with a secret passphrase, use this command:
Youll be prompted for a passphrase, twice (to confirm it) and then a file will be written called example.doc.gpg (WARNING: the original file is still there, in plaintext!). The encrypted file can be decrypted back (as example.doc ) with this command (plus the passphrase, when prompted):
The recipient will be prompted to enter the passphrase to decrypt the file.
To verify a digitally signed file, such as when downloading a piece of software from the Internet, given the download file named example.doc and a signature file named example.doc.sig both in the current directory, use this command:
If the file verifies, the resulting message will include the words Good signature, among much more information (which may include a warning that the signing key is not certified--dont worry about this, for now). If not, Good signature will not appear (other information will be displayed, depending on what happened).
Good luck--and if you want to know more about how this works, keep reading!
) for other options.
The monospace font and the $ character indicate this is an example of a command being entered at the command line. The $ indicates the system is ready to accept a command; the command is typed in and after you type it you press the Enter key to make something happen.

This book is about learning to protect data with encryption. Its a combination primer, story, guide, and handbook on how to use Gnu Privacy Guard (GnuPG) encryption software to protect data in motion (messages or files being sent over the Internet), followed by a brief discussion of how to protect data at rest by using full disk encryption (FDE) on modern operating systems (OSes).
You will learn to use cryptography in a practical way: to encrypt and to decrypt a message or file, to validate a digitally signed message or file, to manage encryption keys, and to work securely with encryption tools.
That means how and why to do it, but not how it works. If you are interested in the science and engineering aspects of how cryptography works--algorithms, acronyms, standards, and specifications--there are many good resources for learning about those topics online. Online is also where youll find the best information about installing encryption software, because online is where its most likely to be up-to-date.
The objective here is to get started doing encryption, not to know why it works or where it came from. However, just for the record--and to make sure were on the same page--here is a brief summary of what cryptography is and what it can do.
Cryptography is the science/practice of writing in secret (crypto=secret, graphy=writing). Cryptographic functions are generally defined as algorithms or protocols, rules that govern how data is processed to turn plaintext (unencrypted data) into ciphertext (encrypted data).
Encryption is what most people think about when they think about cryptography: taking plaintext and turning it into what looks like gibberish, a.k.a. ciphertext.
Done right, encryption protects private data by making it difficult (in some cases almost impossible) for an attacker to uncover plaintext. Depending on circumstances--such as whether the user creates a strong passphrase or whether the user is careful about leaving information vulnerable on their computer--it may be next to impossible--or trivially easy--for an attack to succeed, depending on a users choices.
The goal of using encryption is to make it harder for others to uncover our secrets. The idea is that whatever amount of expertise and computer time is needed to break our encryption should cost more than the perceived value of the information being decrypted.
