Another idea is to use MD5 or SHA algorithm to encode password which in this
situation could be very,very long as only short digest would be stored (or
digest crypted with old crypt() function would be even better)
This shouldn't be a problem for any programmer (not mention perfect ones
from Firebird developer group ;-) ) to include MD5 algorithm to FB1.5 final
Please,Firebird developers - take attention to this proposition and give us
an contrary drawbacks if exists.
