Auto Generator

[Brian K. White]

You get uniqueness by just putting the few lines of generator code in a loop
that keeps trying until the result is not found in your password database.
Rarely will it have to re-try even once, but it could loop at least hundreds
of times in a second so it's not a loop you'd ever be stuck waiting for.

this will use rand to generate 8 completely random alpha-num characters,
that is, it makes no attempt to produce something pronounceable. I imagine a
database of syllables could be found or created fairly easily and instead of
generating random characters, you pick random records from the syllable
file.

This is off the cuff, so I haven't tested it. probably it won't work
immediately but this is the idea.

With a decimal ascii chart that shows all the plain alpha-numeric characters
fall between ascii 48 and 122 in decimal, and the following example from
Laura's Help Files:
then: x = int(RAND() * "100"/"32768") ' Will return numbers 0 to 99.

I come up with:

@keyp  :   if:
       : then: pw(8,alnum) = ""
nxtc   :   if:
       : then: pw = pw { chr(int(rand()*"76"/"32768")+"48")
       :   if: pw co " "
       : then: goto nxtc
       :   if:
       : then: msgbox pw ; end


I was originally going to have
nxtc   :   if:
       : then: x = ...
       :   if: ":;<=>?@[/]^_`" co x
       : then: goto nxtc
       :   if:
       : then: pw = pw { x
       :   if: pw co " "
       : then: goto nxtc

before it occurred to me about the alnum edit. that's why the rand even
bothers to limit it's range from 48 to 122 instead of the simpler 0 to 127:
x = chr(int(rand()*"128"/"32768"))
but since I already had it worked out, it doesn't hurt to use it. In fact it
optimizes the loop so that it needs to re-try less often.
