[sci.crypt] Password choices

jbn@glacier.STANFORD.EDU (John B. Nagle) (07/07/88)

      About five years ago, I posted to the net an "obvious password detector",
a few pages of C intended for use in places such as "passwd" to detect an
attempt to use a password that could be guessed by the usual techniques.
(The algorithm worked by using the fact that the space of letter triples in
English is only 20% populated.)  

      If anyone still has this code, I would appreciate a copy; I no longer
have one.

Choosing good passwords is also aggravated by password aging.
The problem is that the user is suddenly told to choose a new
password immediately.  A local program (which I can't share
but someone out there could write easily) gives you a reminder
when you login if your password is going to expire within a
week.  This gives you plenty of time to cook up a good password.
