Nope
I don't ask users to key in their GUID (they never see it), it just
identifies something about them about which they need know nothing (as you
well know a key to some database info).
I've written my own basic random (so called) number generators and failed. A
lesson learned (at least for me).

I don't think this is a good use for a GUID. Do you really want your users
to have to type in a different 32 character security code every time they
use a particular feature of your site? Typically, more than 8 characters
starts becoming a burden.

Hi Nathan
Just curious myself, how does your version stand up to .NET
Function GUID() As String
GUID = System.GUID.NewGuid().ToString()
End Function
Regards
Maurice

Subject: [WEB400] Random String Generator
Last week's discussion on CAPTCHA made me curious about random number
and random string generation because random codes are harder to break
than say a fixed collection of codes or derived images.
So I set about to write a couple RPG procedures that could be used for
random number and random string generation. For example, the following
screen shows a program for generating random strings of 4-8 characters
based on the lower-case English alphabet.
http://www.radile.com/rdweb/temp/random.html
I found that with even a limited alphabet, the procedure can generate
thousands of unique strings of 4-8 characters. It was just interesting;
A curiosity.
I don't have an immediate use for something like this, but I think it
will come in handy sometime in a toolkit.
Nathan.
