Sign and verify message by ed25519

[Ja7ad]

Description

Currently SignMessageWithPrivateKey and VerifyMessage support bls private key.

pactus/www/grpc/utils.go

Lines 22 to 43 in 2bcb8d6

	func (*utilServer) SignMessageWithPrivateKey(_ context.Context,
	req *pactus.SignMessageWithPrivateKeyRequest,
	) (*pactus.SignMessageWithPrivateKeyResponse, error) {
	prvKey, err := bls.PrivateKeyFromString(req.PrivateKey)
	if err != nil {
	return nil, status.Error(codes.InvalidArgument, "invalid private key")
	}
	sig := prvKey.Sign([]byte(req.Message)).String()
	return &pactus.SignMessageWithPrivateKeyResponse{
	Signature: sig,
	}, nil
	}
	func (*utilServer) VerifyMessage(_ context.Context,
	req *pactus.VerifyMessageRequest,
	) (*pactus.VerifyMessageResponse, error) {
	sig, err := bls.SignatureFromString(req.Signature)
	if err != nil {
	return nil, status.Error(codes.InvalidArgument, "signature is invalid")
	}

Ideal solution

Support BLS and ED25519 for sign and verify message.
