Functions ¶

func CheckIndexes ¶

func CheckIndexes(ec elliptic.Curve, indexes []*big.Int) ([]*big.Int, error)

Check share ids of Shamir's Secret Sharing, return error if duplicate or 0 value found

func Create ¶

func Create(ec elliptic.Curve, threshold int, secret *big.Int, indexes []*big.Int) (Vs, Shares, error)

Returns a new array of secret shares created by Shamir's Secret Sharing Algorithm, requiring a minimum number of shares to recreate, of length shares, from the input secret

Types ¶

type Share struct {
	Threshold int
	ID,
	Share *big.Int // Sigma i
}

func (share *Share) Verify(ec elliptic.Curve, threshold int, vs Vs) bool

type Shares ¶

type Shares []*Share

func (Shares) ReConstruct ¶

func (shares Shares) ReConstruct(ec elliptic.Curve) (secret *big.Int, err error)

type Vs ¶

type Vs []*crypto.ECPoint // v0..vt
