Encryption

Abstract

From the time of Julius Caesar and the “Caesar shift” algorithm, people have been using encryption to protect information from prying eyes. To use encryption properly, you need to understand how data moves through systems, from storage to where the data is presented. If you are not careful, there will be places where encrypted data will spill out unencrypted. You also need to understand that encryption is just one part of securing your information. Even after you set up encryption, you need to concern yourself with ghost data that may be left behind in storage unencrypted.
