Random password

Sun. Sep. 9th, 2007 12:15 PM If you're using passwords of any type on your site, it is best to keep them random. That way they cannot be easily guessed at by intruders.
First, it's good to know a little about ASCII characters. Every character your keyboard can type is actually represented by a number. So the letter A is represented by 65. The letter Z is represented by 90. So all you need to do is generate a series of random numbers, each number between 65 and 90. That would give you a way to find the equivalent letters.
If you want to include numbers too, those are found between spots 48 and 57. I wouldn't use the spots between 57 and 65 - those are odd characters like colons.
So let's say you want to create a 7 character password that contains a random assortment of letters and numbers. You could do something like this:
Randomize()
PassLen = 0
CurrPass = ""
do while PassLen < 7
CurrLtr = Int((42 * Rnd()) + 48)
if CurrLtr < 57 or CurrLtr > 65 then
CurrPass = CurrPass & Chr(CurrLtr)
PassLen = PassLen + 1
end if
loop
