Schnorr signature on FourQ for Qubic

Usage

Important: Note that, in the context of Qubic, subSeed does NOT mean private key!
Key generation goes in this order:
seed -> subSeed -> privateKey -> publicKey
For more information on generating the different key types in Go see go-node-connector/wallet.go.

Signature generation

package main

import "github.com/qubic/go-schnorrq"
import "fmt"

func _()  {
	
	// Fill with your data
	var subSeed [32]byte
	var publicKey [32]byte
	var message [32]byte
	
	singature, err := schnorrq.Sign(subSeed, publicKey, message)
	if err != nil {
		fmt.Printf("Error: %s\n", err.Error())
	}
}

Signature verification

package main

import "github.com/qubic/go-schnorrq"
import "fmt"

func _()  {
	
	// Fill with your data
	signature := [64]byte{}
	messageDigest := [32]byte{}
	publicKey := [32]byte{}
	
	err := schnorrq.Verify(publicKey, messageDigest, signature)
	if err != nil {
		fmt.Printf("Error: %s\n", err.Error())
	}
}

Roadmap

• Signature Generation
• Signature Verification
• Tidy up code / tests
• Move order package somewhere else?
