)

Secure comparison result.

Deprecated: Since 0.11. Use "compare.Match..." constants instead.

Types

type SecureCompare

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

SecureCompare is an interactive protocol for two parties that compares whether they share the same secret or not.

func New

func New() (*SecureCompare, error)

New prepares a new secure comparison.

func (*SecureCompare) Append

func (sc *SecureCompare) Append(secret []byte) error

Append adds data to be compared.

func (*SecureCompare) Begin

func (sc *SecureCompare) Begin() ([]byte, error)

Begin initiates secure comparison and returns data to be sent to the peer.

func (*SecureCompare) Close

func (sc *SecureCompare) Close() error

Close destroys Secure Comparator.

func (*SecureCompare) Proceed

func (sc *SecureCompare) Proceed(data []byte) ([]byte, error)

Proceed continues the comparison process with peer data and returns a reply. Comparison is complete when this method returns nil successfully.

func (*SecureCompare) Result

func (sc *SecureCompare) Result() (int, error)

Result returns the result of the comparison.
