How to generate user passwords

[dunbarx at aol.com]

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.

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.
