sounds like a really fun concept that should be shared here too :D
You're viewing a single thread.
I always thought this was such a cool concept when I was administrating a Hashicorp Vault server. I made 7 fragments for 7 keyholders, and required that 4 or 5 of them (can't remember) enter their fragments to unlock the Vault server.
This is probably implemented with Shamir's secret sharing algorithm or similar.
From the git repo;
Q) How does this work?
A) This uses the Shamir Secret Sharing Scheme to break an encryption key into parts that can be recombined to create the original key, but only requiring a certain threshold to do so. I've adapted Hashicorp's implementation from their vault repo
