psst is a new implementation of Shamir's Secret Sharing: https://github.com/Sjlver/psst

From the README:

`psst` is a system for storing secrets without a single point of failure. `psst` helps the user to split a secret into up to four parts. Each part in isolation reveals nothing about the secret (except its length). Any two parts combined allow the secret to be restored.

The main goal of `psst` is simplicity. It is a system that can be used with just pen, paper and a six-sided dice. `psst` is great for people who want to deeply understand what they do and verify every step, and for anyone who has fun with information theory and cryptography.

This question will resolve "YES" if any security flaw is reported in the next 30 days (before this market closes). I will use a generous definition of security flaw, and count everything that makes the system less secure than it might have been intended.

This question works like a bug bounty. You can buy cheap YES shares and earn Mana for finding a problem in psst.
