custom signature scheme: dial attempt failed: proto: can't skip unknown wire type 6 for crypto_pb.PublicKey

[helinwang]

Hi,

I wrapped a custom priv/pub signature scheme to implement the go-libp2p-crypto.PrivKey and go-libp2p-crypto.PubKey interface. But got the following error when running the chat example:

dial attempt failed: proto: can't skip unknown wire type 6 for crypto_pb.PublicKey

Is custom signature scheme currently supported?

The default chat.go works for me.

This two commits add support to the BLS signature scheme:

https://github.com/helinwang/go-libp2p-crypto/commit/e0b70571efc4c1424523637c01f89488c04133e0 https://github.com/helinwang/go-libp2p/commit/5025955d87a24cd0dd2aa642521ff43e7118115b

Any possibility for it gets merged? (adds a new dependency to "github.com/dfinity/go-dfinity-crypto/bls" though.)

Btw, I have not used gx before, I have published my own version of go-libp2p-crypto (hash is here: https://github.com/helinwang/go-libp2p-crypto/commit/e0b70571efc4c1424523637c01f89488c04133e0#diff-d95150d9db6fb31091770e6d6105b08dL1 ), will it be persisted on IPFS forever?

Thank you!

will it be persisted on IPFS forever?

Not unless someone pins it.

In your public and private key's Bytes() function, you'll need to wrap your serialized key in a github.com/libp2p/go-libp2p-crypto/pb.{PublicKey,PrivateKey} protobuf. Take a look at the Bytes() implementation for Ed25519 and RSA.

We'll probably want to take a close look at the BLS implementation but I'd love to include this if you make a PR.

@helinwang Any update on including BLS signature scheme in Libp2p?

Hi @aratz-lasa I don't have plan to spend time on this. Please feel free to use the code if you are working on this.
