I love the way I would keep my stuff safe:

Now you just need to disperse the horcruxes around the house on various USBs or online locations and hope you can recall where they all are!

This is cool! This could be a handy way to store important private keys like internal root CA keys in known locations that are distributed across an infrastructure. Oh man, maybe even in a vault file for secrets you don’t need often like break glass credentials and the like. Such a cool and unique idea!

that’s super cool, almost zero use case but if you have a super sentqtive string (such as a bank or wallet code) I guess it’s a good layer of offline security

Incredibly cool, will def try this

Cool project :D probably not a real use case, but funny enough to try it out !!!

I’ve always liked this, it has pretty much everything you could want in a personal project: a catchy name and a whimsical idea that is just on the edge of being actually practical.

This basically just means the files themselves become the authentication.

I don’t see a singe use-case, where you couldn’t just use normal private-key encryption and just save the private key to a file somewhere else. And if you want to distribute it to multiple locations, so that you need all of them, then there are also encryption methods for that.
