Hyperbacked

A clone of Superbacked, written in Rust.

Basically, it stores secrets securely using printable PDFs that contain encrypted QR-Codes. The encrypted backup can optionally be sharded, so that it can be distributed across many trusted people, with only a configurable subset of shards being required to decrypt the secret.

Features

• Written in pure, 100% safe Rust
• Free, open-source, and auditable
• Supports Plausible Deniability, Secret Sharing, and 256-bit AES-GCM encryption.
• Runs on Windows, macOS, and Linux with a native GUI using iced
