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