Encrypted_share.t list * Commitment.t list * proofLets a dealer share a secret with a set of participant by breaking it into pieces, encrypting it with the participant's public keys, and publishing these encrypted shares. Any t = threshold participants can reconstruct the secret. A zero-knowledge proof is produced showing that the dealer correctly followed the protocol, making the protocol publicly verifiable.
