Have you ever used Java’s keytool? A simplistic command line tool that’s a pain if you use it only once in awhile.
But here comes KeyTool IUI to the rescue:
A great UI to create and manage keys and certificates and more . . .
I’m sad to tell you that Bob (yellowcat) the developer of KeyTool IUI told me that it’s no longer available. He sold the software and all you can do is try to download an old copy of it somewhere from the internet.
Good news! The tool is now open source: http://code.google.com/p/keytool-iui/
