/**
 * This class provides a tool for encrypting configuration properties.  It can be run using the
 * script that comes with the distribution bundle (.tar.gz file).  The result will be the encrypted
 * and base 32 encoded property value with the required encryption prefix.  For example:
 *  * {@code
 * $ encrypt-property.sh mypassword
 *   Property Value: mypassword
 *   Creating and initializing the encryption engine...
 *   Creating a special output stream to do the work...
 *   Reading from the input and writing to the encrypting output stream...
 *   Purging any plaintext hanging around in memory...
 *   Encrypted Value: {AES-128}UqlfuKDglzWM7VamTIb8XA==
 * }
