# go-dleq

This repo contains an implementation of cross-group discrete logarithm equality as specified in [MRL-0010](https://www.getmonero.org/resources/research-lab/pubs/MRL-0010.pdf). In addition to what's specified in the paper, it contains an additional proof of knowledge of the witness ie. a signature on both curves. Currently, secp256k1 and ed25519 are supported. The library is written such that other curves can be added.

## Usage

```go

import (

    "github.com/athanorlabs/go-dleq"

    "github.com/athanorlabs/go-dleq/ed25519"

    "github.com/athanorlabs/go-dleq/secp256k1"

)

curveA := secp256k1.NewCurve()

curveB := ed25519.NewCurve()

x, err := dleq.GenerateSecretForCurves(curveA, curveB)

if err != nil {

    panic(err)

}

proof, err := dleq.NewProof(curveA, curveB, x)

if err != nil {

    panic(err)

}

err = proof.Verify(curveA, curveB)

if err != nil {

    panic(err)

}

```
