August 07, 2007 How To Get Your WPA Key Onto Your S60 Device Posted by Dameon Welch-Abernathy at 12:37 PM | Categories: Tips and Tricks

Security and convenience are often at opposite ends of the spectrum. One of the challenges security-conscious people have is configuring mobile devices to use the insanely complex WPA keys we use for our WiFi access points. Imagine typing something like the following with a typical 12-key phone keyboard:

6t/~:w]k528U'm2PIV}_W(|]SE~^BcM"2|\+UHc`F2g2$IdI}rcFG_ovGF9hg6a

While this random gibberish ensures your WiFi access point is not going to be broken into anytime soon, that's hard to type on a regular keyboard, much less a 12-key keypad!

The solution I came up with might be heresy to some security folks, given that you essentially have to communicate your WPA key in the clear. The likelihood of anyone knowing what that random bit of gibberish goes to--assuming they're listening--is probably pretty small. In my mind, it's an acceptable risk.

I SMS my WPA key (without any explanatory text) to myself. Some operators provide a way to SMS their customers over the web. Others provide an email interface--my preferred method. Check with your operator. This gets the WPA key into a text message on my phone. I use the Copy and Paste feature in S60 phones, as Johanna demonstrates in her latest blog entry, though she uses a haiku she wrote. Same idea, except you paste that blob of text where you enter the WPA key.

Try it out and let me know what you think by leaving a comment.

Ciao

why don't you just save it to a txt file, copy the file to the phone and then open it, copy and paste and that's it? then delete the file.

Have a look at Devicescape (www.devicescape.com)

Welcome to the S60 browsing team, Dameon! This is a great little tutorial. If anyone's using Firefox (as I would imagine they are) there's a GREAT little Google Plugin available from labs.google.com called "Send2Phone". It puts a little cellphone icon in the top right of your browser that you can click to open up an SMS interface. It's easily the handiest thing that I have on my browser.

I just create an iCal entry with the random data I want to send, sync it and then get it from the calendar.

The text file/ical stuff also works as ways to get the data across.

I use the Google Send2Phone plugin frequently. Same idea, but I think that only works in North America. Could be wrong.

Okay, fewer key presses - check, secure - check.

Install QuickMark mobile barcode reader.
Goto http://www.quickmark.com.tw/En/diy/?qrEncrypt and enter your WPA key and an encryption key and click on generate.
An encrypted QRcode will be displayed, then you just capture it with your S60 device, enter the decryption key and you will then be able to copy and paste the decrypted text.

Do I win a prize?

That website is useful. However, the Barcode reader on the N95 won't offer to decrypt, so all I end up with is gibberish. It also doesn't offer to let me save the data it scans in a useful format (e.g. for the clipboard) either. Nice thought in theory, but doesn't seem to work in practice.
