You could in theory have a digital safe that you yourself can open with one key, and a quorum set of 2 keys that require both. You distribute 1/2 combination keys to your kids and keep one yourself. When you die your 1/2 key is passed to the kids who can now open the data. The keys themselves are useless without the other keys so anyone in the chain of custody of the key until it reaches your kids wouldn't be able to open the data. No one would have to have your singular key.

- kirushik 7y agoI've wrote https://bs.parity.io/#/ https://bs.parity.io/#/ exactly for this; it also tries to avoid the most obvious opsec mistakes, like trusting your printer too much =) BananaSplit is of very experimental quality, it hasn't been battle-tested and independently reviewed yet. But at least it's there, it's FOSS, and I encourage you inspecting the code, contributing to it, or re-hosting the HTML.
