[ DEAD MAN'S SWITCH ]
Canary Vault
Encrypt sensitive files. Split the decryption key among trusted peers using Shamir's Secret Sharing. Check in regularly. If you go silent, your peers reconstruct the key and release the files.
01
ENCRYPT
Files encrypted with AES-256-GCM in your browser. Nothing leaves your device.
02
SPLIT
Decryption key split into N shares. K shares needed to reconstruct.
03
DISTRIBUTE
Give each share to a different trusted peer. Shares are useless alone.
04
CHECK IN
Regular heartbeat proves you're active. Miss it and the canary triggers.
