At present officially not possible. You can try to experiment with the
services API that is already in code, however it is not officially
supported/tested.

Ask for the algorithm of password encryption (as far as I remember this is
simple Unix crypt algorithm). There are components in C/C++ that do this
(ask in Firebird-Support group). Then instead of writing password in plain
text put the en-crypt-ed one. It should work.

You can also fork a gsec command-line tool for this.
