Hello, All.

  Is it intentional that database cannot be encrypted via remote connection if encryption plugin requires key obtained from application callback?
  I'm getting following error:

Statement failed, SQLSTATE = 42000
unsuccessful metadata update
-ALTER DATABASE failed
-Missing correct crypt key

  Everything works well if connection is embedded or key is provided from an internal source.


Encryption of database using key passed from application over the wire works well in at least 2 known to me plugins:
- DbCrypt_example/KeyHolder_example present in firebird distro
- one more closed-source plugin I've used to deal with
