Use at your own risk!
This iOS/Android app will allow you to make a distributed and redundant backup of your nostr private key.
- Enter your nostr private key (nsec...), the app fetches your nostr contacts.
- Choose as many contacts as you want (mininum of 2). For example: select 7 contacts.
- Click backup, now your private key is split in 7 pieces (using Shamir's Secret Sharing)
- On the next page, you must indicate how many of the pieces are needed to reconstruct your full private key. For example: 3.
- The app sends an encrypted DM to your 7 nostr contacts, each receive a piece of your private key
- Ask your 7 contacts for the piece they received.
- Tell the app how many pieces you received from your contacts, for example 4. If you have less than the minimum you indicated during backup, the recovery will fail.
- Enter the pieces (for example: 4)
- The private key is recontsructed, the app logs you in with the private key and shows your list of contacts.
- Swipe right to see you profile, where you have the ability to copy your private key.
