Password is encrypted both on client and server.
If you want to add just option to firebird.conf, how would you
solve situation having one server using new algorithm,
second server usgin old algorithm, and client trying
to connect to both.
Or how would you solve upgrading ? i.e. after changing
configuration to use different algorithm, existing passwords
in security database would become invalid.
