Functions

func ParsePublicKeyFile

func ParsePublicKeyFile(filePath string) (*ecdsa.PublicKey, error)

func UnmarshalKey

func UnmarshalKey(publicKey []byte) (*ecdsa.PublicKey, error)

func Verify

func Verify(payload []byte, signature []byte, publicKey *ecdsa.PublicKey) (bool, error)

verify verifies a signed payload

Types

type Signer

type Signer interface {
	Sign(payload []byte) (signature []byte, publicKey []byte, err error)
}

func NewSigner

func NewSigner(privateKeyPath string) (Signer, error)

NewSigner returns a signer object. It requires a private key file path. To generate a valid key use openssl tool. Ex: openssl ecparam -name prime256v1 -genkey -noout -out ec.key

func NewSignerFromPKey

func NewSignerFromPKey(r io.Reader, pk *ecdsa.PrivateKey) Signer

NewSignerFromPKey returns a signer from a io.Reader and a *ecdsa.PrivateKey.
