SSSS is a slightly tweaked version of B. Poettering’s implementation of Shamir’s Secret Sharing.

SSS is a mechanism by which N people may each have a piece of of information, such that when any M people come together the pieces can be used to reproduce a secret – but if only M-1 pieces are brought together, you have zero bits of the secret.

My fork brings more consistent use of stdout/stderr (allowing for automation of the programs), the ability to make a failure to memlock a fatal error, and simplified build/install steps.
