If you set an encryption policy on an empty database object, as blocks are written to that object, they are encrypted.

The following steps set an encryption policy on an empty Type I area, and then shows the status of the area after a table is defined and loaded with data:

1. Create an encryption policy for an empty area with EPOLICY MANAGE ENCRYPT:

   proenv>proutil t1demo -C epolicy manage area encrypt "DataArea100" OpenEdge Release 12 Encryption policy setting for Area DataArea100 in Area 100 Cipher specification setting to AES_CBC_128 completed.

2. Create a table in the area and load data into it (not shown).
3. Check the encryption status of the area with EPOLICY SCAN:

   proenv>proutil t1demo -C epolicy scan area "DataArea100" OpenEdge Release 12 AREA DataArea100 / 100 CURRENT AES_CBC_128 V:0 127 of 127 blocks encrypted

   As new records are written to the DataArea100 area, they are encrypted. The output shows that the area has grown from 1 block to 127 blocks and that they are all encrypted.
