/**
 * Encrypted (database like) table.
 *
 * The same like Table, but the file into which the data is stored is saved
 * encrypted with the symetric key. This implementation works with it in a
 * simple way: <br>
 * Open - decrypts the table, all operations then work on the decrypted file.
 * Close - encrypts the table.
