type DefaultMessageAuthenticator ¶
type DefaultMessageAuthenticator struct {
// contains filtered or unexported fields
}
DefaultMessageAuthenticator is an HMAC based MessageAuthenticator
func NewDefaultMessageAuthenticator ¶
func NewDefaultMessageAuthenticator(hashFn func() hash.Hash, key []byte) *DefaultMessageAuthenticator
NewDefaultMessageAuthenticator returns a newly initialized DefaultMessageAuthenticator
func (*DefaultMessageAuthenticator) AuthenticateMessages ¶
func (a *DefaultMessageAuthenticator) AuthenticateMessages(data []byte) ([]byte, int, error)

func (*DefaultMessageAuthenticator) GetMessageAuthenticationHeader ¶
func (a *DefaultMessageAuthenticator) GetMessageAuthenticationHeader(data []byte) ([]byte, error)
GetMessageAuthenticationHeader returns a header produced for the given data
func (*DefaultMessageAuthenticator) GetMessageAuthenticationHeaderLength ¶
func (a *DefaultMessageAuthenticator) GetMessageAuthenticationHeaderLength() int
GetMessageAuthenticationHeaderLength returns the length (in bytes) of headers produced by the MessageAuthenticator
func (*DefaultMessageAuthenticator) ReadNext ¶
func (a *DefaultMessageAuthenticator) ReadNext(r io.Reader) ([]byte, error)
ReadNext reads and verifies HMAC on a single messages
func (*DefaultMessageAuthenticator) WithHashFn ¶
func (a *DefaultMessageAuthenticator) WithHashFn(hashFn func() hash.Hash) *DefaultMessageAuthenticator
WithHashFn modifies the hash function and hash length on a DefaultMessageAuthenticator and returns it
type MessageAuthenticator ¶
type MessageAuthenticator interface {
GetMessageAuthenticationHeaderLength() int
GetMessageAuthenticationHeader([]byte) ([]byte, error)
ReadNext(io.Reader) ([]byte, error)
AuthenticateMessages([]byte) ([]byte, int, error)
}
MessageAuthenticator represents a message authentication service
