Types

type Ed25519Signer

type Ed25519Signer struct {
	// contains filtered or unexported fields
}

func (*Ed25519Signer) Sign

func (s *Ed25519Signer) Sign(message []byte) ([]byte, error)

func (*Ed25519Signer) Verify

func (s *Ed25519Signer) Verify(message, sig []byte) (bool, error)

type Signer

type Signer interface {
	Sign(message []byte) ([]byte, error)
	Verify(message, sig []byte) (bool, error)
}

Signer is the interface implemented by any value that has Sign and Verify methods. Signers are able to sign messages and verify them using a signature.

func NewEd25519Signer

func NewEd25519Signer() Signer

NewEd25519Signer creates an ed25519 signer from scratch.

func NewEd25519SignerFromFile

func NewEd25519SignerFromFile(privateKeyPath string) (Signer, error)

NewEd25519SignerFromFile creates an ed25519 signer using existing private and public keys. It also checks that keys are usable.
