Macromedia Flex and Password Encryption

I was researching some different text encryption algorithms at work and stumbled across one that works fairly well. If you want to enable a simple means of security then you might find this useful. This beats storing a user’s password in a SharedObject in plain text.

I stumbled across the following algorithm written in JavaScript:
http://javascript.internet.com/passwords/xor-encryption4.html. I decided to convert the code to ActionScript so I could run it in my Flex project. It turns out that I only to make one or two minor tweaks and everything ran flawlessly. You can view the results below. Leave the default text or add your own and then click “encrypt”.

and here’s the code that makes it all happen:

</p> <p> 10)<br /> {<br /> prand = (Number(prand.substring(0, 10)) + parseInt(prand.substring(10, prand.length))).toString();<br /> }</p> <p> prand = (mult * prand + incr) % modu;<br /> var enc_chr = “”;<br /> var enc_str = “”;</p> <p> for(var i=0; i 10)<br /> {<br /> prand = (Number(prand.substring(0, 10)) + parseInt(prand.substring(10, prand.length))).toString();<br /> }</p> <p> prand = (mult * prand + incr) % modu;<br /> var enc_chr = “”;<br /> var enc_str = “”;</p> <p> for(var i=0; i</p> <p>
