9  * An implementation of Properties which stores the values encrypted.
10  *
11  * The use is transparent from the user point of view (use as any Properties instance),
12  * except that get, put and putAll do not handle encryption/decryption.
13  *
14  * This means that get returns the encrypted value, while put and putAll
15  * puts given values without encrypting them.
16  *
17  * It this thus recommended to void using them, use setProperty and getProperty instead.
