Kaitiaki Guardian Backup
Split one secret into guardian bundles. Each guardian holds the encrypted payload and one key share. Any threshold of guardians can recover it. Nothing leaves your browser.
One secret, sealed
Kaitiaki encrypts your secret in the browser. The plaintext never leaves your machine.
N guardian bundles
Each guardian receives one bundle. A bundle holds the full encrypted payload plus one key share.
Any k recover
Bring any threshold of guardians together and their shares rebuild the key and decrypt the secret.
Client-side, offline
The pages are fully self-contained. Save them to disk and run the whole process with no network.
Kaitiaki as a service
The tool is free, forever. The service is the practice. A Butler guides your placement session over video: your files, your guardians, your machines — we see screens, never bytes, and we never hold a bundle. Every year, a one-hour drill rehearses the recovery with your guardians so the plan works before it is needed. Offered globally, delivered remotely.
