) [ scheme to encrypt all probable passwords with all seeds ]
Given a password file for a machine with fewer than 4096 users, a
considerable savings of resources may be had by simply encrypting
all probable passwords with only the seeds actually present in
the password file.

For a system with 10 legitimate users, you should need at most
10 encryptions \(em less if two or more passwords share a seed.


For a system with 4000 legitimate users, this doesn't work out
as well.  Concentrate on password-guessing for "root" or the owner
of the files in which you are interested.
