Open Source Tool Uses Shamir's Secret Sharing For Distributed File Recovery

TL;DR

Rememory splits encrypted files across trusted friends using threshold cryptography, requiring any N-of-M shares to decrypt without trusting any single party.

Key Points

  • Implements Shamir's Secret Sharing to distribute decryption keys—e.g., 3-of-5 friends required to recover file
  • Self-contained browser-based recovery tool (recover.html) works offline with zero server dependency
  • Uses age encryption with open-source code and cryptographic audit documentation available on GitHub
  • Each friend receives isolated bundle; no single person or service can access encrypted data alone

Why It Matters

This addresses a real security problem: how to enable trusted access to critical files without creating a single point of failure or trusting a centralized service. For developers, sysadmins, and security-conscious users, it provides a practical implementation of threshold cryptography that's actually usable—no complex setup, no servers to compromise, and verifiable open-source code.
