Web UI
Good for one-off workflows and visual confirmation.
Getting started
Safeparts splits one secret into recovery shares so recovery requires cooperation, not one perfect backup.
Mental model
Section titled “Mental model”Safeparts turns one secret into n shares. Recovery requires any k shares.
- Fewer than k shares: an attacker learns nothing useful.
- Any k shares: you can reconstruct the original secret.
Practical limits: 1 <= k <= n <= 255.
Pick a recovery plan
Section titled “Pick a recovery plan”The hard part is logistics: who holds which share, how you contact them, and what you do when someone is unavailable.
Start with Use cases to choose k/n and a distribution you can actually run.
Pick an interface
Section titled “Pick an interface”CLI
Good for automation and repeatable runbooks.
TUI
Good for offline machines and interactive terminal workflows.

Do a practice run (recommended)
Section titled “Do a practice run (recommended)”Do this once with a fake secret so you learn the flow before you trust it with a real key.
- Pick k=2, n=3.
- Split a synthetic secret such as example-secret.
- Store the 3 shares in 3 different places (even temporarily).
- Recover using any 2 shares.
- Delete the synthetic shares.
Before you split a real key
Section titled “Before you split a real key”Read Security and follow the storage rules there. Safeparts can remove single points of failure, but it can’t fix a bad distribution.
Use cases
Pick k/n and a realistic share distribution.
Encodings
Choose between machine-friendly and human-friendly share formats.
Security
Threat model and safe handling rules.
Troubleshooting
Common failure modes and fixes.
