Checking password

Hi,

Is there any way to check if user's password is correct without actually connecting to Oracle?

I'm interested in some PL/SQL function, that will to do this. It would look like:

function is_password_correct(username varchar2, password varchar2) return number is ...

Is there anywhere available source of function that codes the password into string as shown in DBA_USERS view?
