Hi all,

I've been working on a private-key backup system using Shamir secret sharing for security and redundancy.

Each secret is divided into n "shares", where k of n shares are required to recover the secret. The shares are put on a range of devices that you (or people you trust) control. If your secret is lost, just collect the shares to recover it.

The app makes this workflow easy.

FAQ

Doesn't spreading my key compromise security?
Shamir secret sharing is information theoretically secure. As long as k of n shares are not compromised, your key will be safe.

What if I don't own many devices?
Owning a few devices is a requirement. However, you can also use your friend's devices and cloud services. For example, you could keep a share on your laptop, on your phone and on Dropbox. You could even print one out.
