"Super-useful one use tool"
Easy to use, gets the job done.
Some AntiVirus programs flag it as a trojan when the worst they should be flagging it as is a hacker tool, but even that is enough to put off people who don't know what's going on. Visit the developer's site for a post on this issue.
WirelessKeyView is the kind of utility that you'd only pull out if one of your relatives had lost the piece of paper with their WiFi password on it and then call you up to 'fix the problem'. I think i've used it something like 3 times in the space of 5 years, so it's not really a money spinner, but thankfully the author is giving it away for free.
In the end it's down to whether you trust CNet enough to have tested it and found it malware free.
