README

Merlin is a STROBE-based transcript construction for zero-knowledge proofs. It automates the Fiat-Shamir transform, so that by using Merlin, non-interactive protocols can be implemented as if they were interactive.

For more details, see dalek-cryptography/merlin.

Types

type Transcript

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

func NewTranscript

func NewTranscript(appLabel string) *Transcript

func (*Transcript) AppendMessage

func (t *Transcript) AppendMessage(label, message []byte)

Append adds the message to the transcript with the supplied label.

func (*Transcript) ExtractBytes

func (t *Transcript) ExtractBytes(label []byte, outLen int) []byte

ExtractBytes returns a buffer filled with the verifier's challenge bytes. The label parameter is metadata about the challenge, and is also appended to the transcript. See the Transcript Protocols section of the Merlin website for details on labels.
