BLS GoDoc

Boneh–Lynn–Shacham (BLS) signature scheme implemented in Go. https://en.wikipedia.org/wiki/Boneh%E2%80%93Lynn%E2%80%93Shacham

This package uses the BN128 Pairing Go implementation from https://github.com/arnaucube/go-snark/tree/master/bn128

Usage

bls, err := NewKeys()
assert.Nil(t, err)

fmt.Println("privK:", bls.PrivK)
fmt.Println("pubK:", bls.PubK)

m := []byte("test")
sig := bls.Sign(m)
fmt.Println("signature:", sig)

verified := bls.Verify(m, sig, bls.PubK)
assert.True(t, verified)
