1) Encryption of DATA -- gives penalty about 2-3% only.


2) If you encrypt only structure, then your DATA still can be catched,
generally speaking by HEAD EDITOR, right ?

    Yes Valentina's format is COLUMNAR, so it will be VERY HARD,
    I'd say impossible to get correct RECORD with all N fields,
    But who know, may be even LastName of some person in some db is
    huge secret.
