What's new?

I've added a couple of new tools to the collection recently.

IP address analyser

Not as exciting as it sounds - just shows the class of a basic IP v4 address, plus the integer network number and host IDs for those once-in-a-blue-moon occasions when you really, really need that.

Base64 encode/decode

Does what it says on the tin.

OpenSSL and SSH keys

Generating RSA key pairs is a lot harder than it should be. On a Linux console, it's relatively straightforward but requires a "recipe" list of OpenSSL commands which are anything but and which I keep forgetting :/ For folk doomed to only use Windows, it's close to impossible. So, here's a simple key generator page!

Also, we had a need recently to convert an existing PEM-format public key into the equivalent format required by SSH for its access list; that proved rather trickier than you'd expect, and I ended up creating a (hopefully!) foolproof converter - maybe this can save some other poor soul turning their brain inside out too...

Data URI generator

We had a need to convert some binary files into data:-format URI strings recently, so as usual I ended up writing a little tool to do the job rather than fudge it yet again!
