Functions

func BatchVerify added in v0.12.0 

func BatchVerify(msg []byte, keys []*Key, sigs []*Signature) bool

func HashScalar added in v0.9.8 

func HashScalar(k *edwards25519.Point, outputIndex uint64) *edwards25519.Scalar

func KeyMultPubPriv added in v0.5.0 

func KeyMultPubPriv(pub, priv *Key) *edwards25519.Point

Types

type BatchVerifier added in v0.12.1 

type BatchVerifier struct {
	// contains filtered or unexported fields
}

BatchVerifier accumulates batch entries with Add, before performing batch verification with Verify.

func NewBatchVerifier added in v0.12.1 

func NewBatchVerifier() BatchVerifier

NewBatchVerifier creates an empty BatchVerifier.

func (*BatchVerifier) Add added in v0.12.1 

func (v *BatchVerifier) Add(publicKey *Key, message, sig []byte)

Add adds a (public key, message, sig) triple to the current batch.

func (*BatchVerifier) Verify added in v0.12.1 

func (v *BatchVerifier) Verify() bool

Verify checks all entries in the current batch, returning true if all entries are valid and false if any one entry is invalid.

If a failure arises it is unknown which entry failed, the caller must verify each entry individually.

Calling Verify on an empty batch returns false.

type CosiSignature added in v0.5.0 

type CosiSignature struct {
	Signature Signature
	Mask      uint64
	// contains filtered or unexported fields
}
