I knew an old guy who hid his keys this way.

Pretty neat. I guess then someone would have to accurately guess what the encrypted message is, along with your password if they want to know your secret. Each could be stored redundantly in various places. And these would appear much less conspicuous than a set of seed plates.

I wonder what the probably would be that someone could accurately get these compared with guessing your 12 word seed. Non-zero, one would think, but most highly unlikely.

It's like the DaVinci Code!
