Hi

EDB2 :

can i have a simple table encryption ?  ( like XOR  )

the internal encryption is too much complex and the file is not more
Compressible.

i need download ( dozens tables every day ) my encryption table compress
with ZIP.

example :

DBISAM :
STANDARD TABLE : 100 MB
ENCRYPTION TABLE : 100 MB
ZIPPED TABLE : 5 MB

-> all OK Smile


EDB2 :
STANDARD TABLE : 100 MB
ENCRYPTION TABLE : 100 MB
ZIPPED TABLE : 99 MB   Frown

->Not Possibile  Frown

is there a solution ?

Tim has built in a high strength encryption and a consequence of that is that it doesn't compress when zipped (the repeating patterns that allow compression are no longer there). He's indicated in other posts that this isn't going to change.

Mauro,

Yes, but you'll have to build it in yourself using triggers and an external
module that performs the encryption on any columns that you wish to have
encrypted.  However, there is a downside that the data won't be searchable
or sortable in any recognizable way.
