func Verify

func Verify(pubkey *PublicKey, message []byte, sign []byte) bool

Verify verifies the provided message

Types

type EdSigner

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

EdSigner represents an ED25519 signer

func NewEdSigner

func NewEdSigner() *EdSigner

NewEdSigner returns an auto-generated ed signer

func NewEdSignerFromBuffer

func NewEdSignerFromBuffer(buff []byte) (*EdSigner, error)

NewEdSignerFromBuffer builds a signer from a private key as byte buffer

func (*EdSigner) PublicKey

func (es *EdSigner) PublicKey() *PublicKey

PublicKey returns the public key of the signer

func (*EdSigner) Sign

func (es *EdSigner) Sign(m []byte) []byte

Sign signs the provided message

func (*EdSigner) ToBuffer

func (es *EdSigner) ToBuffer() []byte

ToBuffer returns the private key as a byte buffer

type PublicKey

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

PublicKey is the type describing a public key

func NewPublicKey

func NewPublicKey(pub []byte) *PublicKey

NewPublicKey constructs a new public key instance from a byte array

func (*PublicKey) Bytes

func (p *PublicKey) Bytes() []byte
