I have a login page that uses will be accessing through a Pocket Windows 2003 PDA/Hand Scanner. I am wanting to make Badges that they can scan to authenticate them. Right now i have them assigned a username and password. I want to make a VERY simple encription so they cant easily get others ID and Pass out of these badges.
I want this to contain the username and password. This will be one barcode in a badge (3 of 9 barcode).
I was thinking something like this string here:
BadgeID = Username & "+" & Password
So the final string would look like this:
i just dont know how i can easily encript this on the badge.
I need to encript this, because they can (if they wanted to) open a notepad on the device, and scan another badge and get their information.
The only way i know how to do this, is get the ASC equvilent, and add like +5 to that...
Any better ideas?
