Work. Project scope has expanded again. But it's a good thing.
Still trying to figure out how to implement partial key escrow in a safe deposit box. Almost every data storage medium that has been invented in my lifetime is now difficult or impossible to find a reader for. So I can't just toss a thumb drive in the box and expect people to be able to read it and run whenever software may contain when I die. Then again, there's nothing to prevent me from replacing it every so often with something newer. But I think I should still include paper directions for how to implement the algorithm, if not actually make it possible to implement it /on/ paper.
And the next step after that, of course, is to buy some fancy paper and design a wax seal.
