Create share

Split a secret into key portions (no account required)

Your secret is split using Shamir's Secret Sharing. Each portion is useless on its own; only when enough portions are combined can the secret be recovered.

End-to-end in your browser — the server never sees your secret

The value you want to protect (e.g. a password or key). It is split entirely in your browser; nothing is sent to the server.

How many key portions to create (e.g. one per person).

How many portions are required to reconstruct the secret (e.g. 2 of 3).
