I was in Malaysia in 1998 programming the Petronus Towers concert hall with a
HC based control system for a large fiber optic project.
The client still owed us quite a bit of money, and I knew if I left town, we
would have a time getting paid. It was that sort of job.
So while the general contractor was on the concert floor calling light patterns
back to me via walkie-talkie, I would take a few seconds here and there to add
a small counting routine, such that after 30 sessions the system would erase
the stack script, and ask for a password from then on (the system was shut down
each night). The stack script was saved in a button.
We got nowhere with collections, and a month after I got back I answered a
frantic call from the client. Long story short, we had a wire transfer in two
days, and I sent them the password that disabled the "virus" and restored the
stack script. The password was "357".
My point is that unless you are defending against the KGB, or are worried that
an LC-savvy agent might be called in, you don't really need a lot of fancy
protection.
Not that there is anything wrong with fancy.

Subject: Re: How to generate user passwords
Bill,
I made this as part of another discussion about speakable passwords.
function speakablePassword theLength
put "bcdfghjklmnprstwyz" into myConsonants
put "aeiou" into myVowels
put "" into myPass
repeat myPasswordLength
if char -1 of myPass is in myConsonants then
if char -2 of myPass is in myConsonants or \
length(myPass = 9) then
put any char of myVowels after myPass
else
if any item of "true,false" then
put any char of myVowels after myPass
else
put any char of myConsonants after myPass
end if
end if
else
put any char of myConsonants after myPass
end if
end repeat
return myPass
end speakablePassword
Since you didn't say what you want to use the passwords for, I don't know if
this will be helpful, but I'm posting it anyway.
