Resilient Activation Codes with Safe32

There's nothing worse than trying to type in an activation code that's written down or spoken over the phone. Was that a "0"? an "O"? a "V"? a "U"? Is it case sensitive?

Safe32 handles all that.

Edit: Bleh, HN strips out the anchor. https://github.com/kstenerud/safe-encoding/tree/master/refer...
