func SignECDSA

func SignECDSA(message VerifiableMessage, keyID KeyID, rand io.Reader) error

SignProto signs a proto that has a proto field Signature.

func SignPKCS1v15

func SignPKCS1v15(message VerifiableMessage, keyID KeyID) error

SignProto signs a proto that has a proto field Signature.

func SignProto

func SignProto(message VerifiableMessage, key []byte) error

SignProto signs a proto that has a proto field Signature.

func ValidateECDSA

func ValidateECDSA(message VerifiableMessage, keyID KeyID) (bool, error)

func ValidateHMAC

func ValidateHMAC(message VerifiableMessage, key []byte) (bool, error)

Check the signature embedded in the protobuf message is correct for the message by recalculating it using the secret key.

Types

type KeyID

type KeyID string

type VerifiableMessage

type VerifiableMessage interface {
	proto.Message
	GetSignature() []byte
}

VerifiableMessage a proto message that has a Signature field. Using the extension interface pattern so that I can read the Signature.
