API Docs

This package provide secret sharing schemes which are publicly veriable and recoverable using a simple t out of n (t,n) threshold system.

A secret value can be escrow to N encrypted shares.

This secret value can be recovered by decrypting at least t amount of shares, and combining them.

Publicly Verifiable Secret Sharing (PVSS) scheme implemented:

Crypto
