Functions

func Reconstruct

func Reconstruct(shares []Share) ([]byte, error)

Reconstruct takes a set of shares and tries to recover the secret from those shares

Types

type Share

type Share struct {
	// X is the x value of the share
	X byte
	// RequiredShares holds the threshold this share was generated for
	RequiredShares byte
	// Index is the index of this share
	Index byte
	// Values contains a list of y values, that were computed using (a different) f(x) = y for each secret byte
	Values []byte
}

Share holds all information a share has
